Technical Training Kits Lab Equipment Manufacturer, Supplier and Exporter in India

Fifty experiment boards are catalogued here as TTK-0001 to TTK-0050, with four further items that belong to other code series and appear to be filed here by mistake. Almost everything in this listing is a single-experiment board: one board, one practical, one bench. That changes how you buy. The question is not which board is best but which experiments your practical sheet sets, how many benches must run each one at the same time, and whether the parts on the board can still be bought when a student destroys one.

What is in the listing, by subject

Boards named after a specific integrated circuit: ask whether the part still exists

Six of these boards name the device they are built around, and that is a real advantage when a syllabus specifies a particular part, because a board built around the named device teaches exactly what the paper asks. It also creates a risk the listing does not mention: when the named device fails, the board is only as repairable as that part is obtainable, and several of the parts named here belong to logic and memory families that have been out of production for a long time. Before ordering any board whose name contains a device number, ask:

• Is the device socketed? A socketed device can be replaced by a technician in a minute; a soldered one means the board goes away for repair or into the bin.
• Are spare devices supplied with the board, and at what price? Order spares with the board rather than after the first failure, because that is when the part is still being stocked.
• Is the part still in production, and is there a current equivalent the board will accept if it is not?
• Would a functionally equivalent modern part satisfy your syllabus, if the paper names a function rather than a part number? Ask the supplier what they would build instead.

The same question applies to the input protection. Ask whether inputs and outputs are current-limited and protected against a reversed supply or a shorted output, because on single-experiment boards student wiring errors are the main cause of failure and protection is the difference between a board that lasts ten years and one that lasts a term.

Device-characteristic boards: what makes one worth buying

Eight boards here plot the characteristic of a component, and they all live or die on the same four points. Ask, for each:

• Current limiting on the device under test. A diode or transistor characteristic is measured by sweeping towards the limits, so the board must protect the device from the student rather than relying on the student to protect the device.
• Whether the device under test is socketed and replaceable, and whether a set of different devices is supplied so the characteristic can be compared across types rather than measured once.
• Which meters the experiment assumes, whether they are built in, and their ranges and resolution, since a characteristic plotted from coarse readings shows nothing in the interesting region.
• The measurement conditions. For the solar cell board (TTK-0023), the illumination source, whether its irradiance is measured, and the cell temperature, because the characteristic moves with both. For the band gap (TTK-0022) and Planck constant (TTK-0013) boards, how the temperature is produced and measured, since in both experiments the temperature measurement dominates the error. Ask whether the oven or lamp is included.

Modulation and optical boards duplicate fuller ranges elsewhere

Six modulation boards here, covering amplitude, frequency, pulse amplitude, pulse width, pulse position and differential phase shift keying, cover ground that the fifty-board Communication and RF Trainers range covers in sequence, and the two fibre optic boards and the antenna board likewise have counterparts there and under Fiber Optics Communication Trainers. If you are building a communication laboratory, start from those ranges. If you need one or two boards to fill a gap in an existing laboratory, these are the right size of purchase, and the questions to ask are whether the carrier and modulating frequencies are adjustable, whether both modulator and demodulator are on the board, whether test points are brought out at each stage, and what instruments the experiment assumes. Ask the supplier to confirm you are not being quoted the same board under two code series.

Four items in this listing belong to other categories

CNC-0006 is a milling machine retrofit kit, CNC-0017 a computer-numerical-control teaching lathe and CNC-0032 a named lathe; all three belong with CNC Trainers, and they are the three codes missing from that listing's sequence. SDS-0003 is a soldering station and belongs with Soldering and Desoldering Stations, where it is likewise the missing code. They are machine tools and bench equipment rather than experiment boards, and they carry their own installation, guarding and extraction requirements, so follow those two pages rather than this one when buying them.

Also worth confirming

Quote the code rather than the name on anything from this listing. Several names in it are near-duplicates distinguished only by a trailing digit, one pair covers the same multiplexer experiment under two codes, two codes cover the same adder and subtractor experiment, and some names carry spelling and formatting faults, so a name alone is not enough to order from. Ask also for the experiment manual with expected readings for every board, the quantity per student group, the supply arrangement and whether each board self-powers or needs a base unit, the socketed devices and spares kit, the supply voltage, frequency and plug type for your country, and the warranty, including whether it covers a device destroyed by a wiring error. Any figure quoted is confirmed in writing on the quotation; ask for its basis.

Related ranges on this site

For a whole laboratory rather than individual boards, start from Basic Electronics Trainers, Digital and Analog Trainers and Kits, Communication and RF Trainers and Power Electronics Trainers. Physics apparatus of the kind several of these boards duplicate is under Other Engineering Lab Trainers. Components are under Electronic Components, the assembly bench under Soldering and Desoldering Stations, and instruments under Testing and Measuring Lab Trainers. Parent range: Training Kits.

Request a quote

Send your practical sheet with the number of benches that must run each experiment at once, and ask for a quote by code with the socketed devices and spares listed. For example Semiconductor Diode Characteristics (TTK-0020) and FET Characteristics (TTK-0025), eight benches each, with the current limiting, the device sockets and a spares kit confirmed in writing. Contact Ray Export for prices, manuals and lead times.

Frequently asked questions

How do we work out which boards and how many to buy?

Start from your practical sheet, not the listing. Because almost every board here carries one experiment, count how many benches must run each experiment at the same time and buy that number of that board. Quote by code rather than name, since several names are near-duplicates distinguished only by a trailing digit, one multiplexer experiment and one adder and subtractor experiment each appear under two codes, and some names carry spelling faults. Ask also whether each board self-powers or needs a base unit, and for the experiment manual with expected readings.

What should we ask about boards named after a specific integrated circuit?

Six boards name the device they are built around, which helps when a syllabus specifies a part, but a board is only as repairable as that part is obtainable, and several named parts belong to logic and memory families long out of production. Ask whether the device is socketed, so a technician can replace it in a minute; whether spare devices are supplied, ordering them with the board while the part is still stocked; whether the part is still made or a current equivalent fits; and whether a functionally equivalent modern part would satisfy your syllabus.

What makes a device-characteristic board worth buying?

Eight boards here plot a component characteristic, including diode and zener, FET, thyristor and optoelectronic devices, and they all depend on four points. Current limiting on the device under test, because the sweep runs towards the limits and the board must protect the device from the student. A socketed, replaceable device, ideally with a set of different devices so characteristics can be compared. The meters assumed, whether built in, and their ranges and resolution, since coarse readings show nothing in the interesting region. And the measurement conditions under which the characteristic is taken.

What should we check on the solar cell, band gap and Planck constant boards?

Measurement conditions decide these experiments. For the solar cell board TTK-0023, ask what the illumination source is, whether its irradiance is measured, and how the cell temperature is known, because the characteristic moves with both. For the band gap board TTK-0022 and the Planck constant by light-emitting diode board TTK-0013, ask how the temperature is produced and measured, since in both experiments the temperature measurement dominates the error. Ask whether the oven or lamp each experiment needs is included.

Should we build a communication laboratory from the modulation boards here?

Probably not. The six modulation boards (TTK-0008, 0010, 0016, 0017, 0019, 0027) cover amplitude, frequency, pulse amplitude, pulse width, pulse position and differential phase shift keying, ground the fifty-board Communication and RF Trainers range covers in sequence; the fibre optic and antenna boards likewise have counterparts elsewhere. Start from those ranges for a whole laboratory. To fill one or two gaps, these are the right size of purchase: ask whether carrier and modulating frequencies are adjustable, whether modulator and demodulator are both on the board, and whether test points are brought out at each stage.

Why are CNC machines and a soldering station in this listing?

They are filed here by mistake. CNC-0006 is a milling machine retrofit kit, CNC-0017 a computer-numerical-control teaching lathe and CNC-0032 a named lathe; all three belong with CNC Trainers, where they are the three codes missing from that listing's sequence. SDS-0003 is a soldering station and belongs with Soldering and Desoldering Stations, where it is likewise the missing code. They are machine tools and bench equipment with their own installation, guarding and extraction requirements, so follow those pages when buying them.

Key takeaways

• One board, one practical, one bench: buy by practical sheet and the number of benches that run each experiment at once.
• Named devices must be obtainable: ask for sockets, spare devices with the order, and a current equivalent.
• Protection decides board life: ask whether inputs and outputs are current-limited and protected against reversed supply and shorted outputs.
• Characteristic boards need current limiting: plus replaceable devices and meters with enough resolution.
• Temperature dominates two experiments: ask how TTK-0022 and TTK-0013 produce and measure it.
• Quote the code, not the name: near-duplicate names and two experiments listed under two codes each make names unreliable.
