Quick answer. Settle one dedicated board per experiment, or a development platform, before anything else, because it shapes the whole order. A dedicated BET board has the circuit pre-built, so students get a reliable result inside a fixed session, but a full syllabus means many boards. The project board trainer and development platforms (BET-0032, BET-0046, BET-0048) let students build the circuit themselves, so one platform serves many experiments, at the cost of longer sessions, a component stock and more supervision. Most departments buy both. Then ask, for every board, whether it is self-contained or needs the base unit and external instruments.
Ray Export lists around 47 basic electronics trainers in the BET series, BET-0001 to BET-0050 across five pages. Each board is built around one experiment from a first and second year electronics syllabus: device characteristics, rectifiers and regulators, oscillators and multivibrators, AC bridges, amplifiers, digital logic, and the base units and development platforms the rest of them sit on. The range is best read as a syllabus checklist, so the table below groups it that way.
| Topic | Codes | Experiments covered |
|---|---|---|
| Device characteristics | BET-0003, BET-0004, BET-0011, BET-0022, BET-0023, BET-0028 | Diode, transistor, FET, DIAC, TRIAC and LDR characteristic curves |
| Rectifiers and regulation | BET-0005, BET-0009 | Rectifier trainer, Zener diode voltage regulator |
| Oscillators and multivibrators | BET-0006 to BET-0008 | Hartley and Colpitts oscillators, Wien bridge oscillator, astable and monostable multivibrators |
| Amplifiers | BET-0029 | BJT amplifiers and emitter follower |
| AC bridges and measurement | BET-0024, BET-0026, BET-0027, BET-0030 | Maxwell bridge, Hay bridge, dielectric constant measurement, Lissajous pattern trainer |
| Digital logic | BET-0043 to BET-0045 | BCD adder and subtractor, arithmetic and logic unit, sum-of-products and product-of-sums implementation |
| Development platforms and workstations | BET-0032, BET-0046 to BET-0048 | Project board trainer, digital circuits development platform, digital workstation, analog-digital circuits development platform |
| Base units and test | BET-0001, BET-0002, BET-0031, BET-0050 | Electrical safety demonstrator, electricity lab trainer, power supply base unit, transistor analyzer |
The sequence is not continuous: BET-0010, BET-0025 and BET-0049 do not appear among the items listed. Every product name ends with the phrase "For Electronics Teaching Labs", which is a naming convention on this site rather than a specification.
This is the decision that shapes the whole order, and it is worth settling before you price anything.
| Approach | What you get | What it costs you |
|---|---|---|
| A dedicated board per experiment | The circuit is pre-built and labelled, students get a result inside the session, and a class can run the same experiment on twelve identical boards. Little can go wrong and little needs setting up. | You buy one board per experiment, so a full syllabus is a large number of items. Students see a working circuit rather than building one, which teaches the measurement but not the construction. |
| A development platform or project board | BET-0032, BET-0046 and BET-0048 let students build the circuit themselves from components, so one platform serves many experiments and supports project work. | Sessions take longer, more goes wrong, and you need a stock of components and more supervision. Fault-finding becomes part of the lesson, which may be the point or may be the problem. |
Most departments buy both: dedicated boards for the experiments that must produce a reliable result in a fixed session, and a few platforms for project and design work.
The BET series stops at the foundation level. For later-year and specialist work, the relevant ranges on this site are Digital Analog Trainers and Kits, Microprocessor Trainers and Kits, Embedded System Trainers, Communication and RF Trainers, Power Electronics Trainers and Instrumentation Trainers. Loose components to stock a project platform are under Electronic Components, and the test instruments the boards are measured with under Testing and Measuring Lab Trainers.
Send your practical syllabus with the number of student groups per session, and ask for the quotation to state for each board whether a power supply is integral and which external instruments are needed. For example Transistor Characteristics Trainer (BET-0004), twelve units, with the manual and a spares kit, and confirmation of whether the base unit is required. Contact Ray Export for prices, manuals and lead times. Parent range: Electronics Lab Trainer Kits.
It depends on what the session must deliver. A dedicated board has the circuit pre-built and labelled, so students get a result inside the session and a class can run the same experiment on identical boards; the cost is one board per experiment, and students learn the measurement rather than the construction. The project board trainer and development platforms (BET-0032, BET-0046, BET-0048) let students build circuits from components, so one platform serves many experiments, but sessions take longer and need a stock of components and more supervision. Most departments buy both.
Ask before you order, because this is the question that most often changes the quotation. Some boards may carry their own power supply; others may need the power supply base unit (BET-0031). Ask too whether the experiment needs an external oscilloscope, function generator or multimeter, and whether measurement points are brought out to labelled sockets or built-in meters are fitted. A board quoted without the instruments it depends on is not a working experiment, so ask for the quotation to state both for every code.
Decide the student group size first. Characteristic-curve experiments, such as the Transistor Characteristics Trainer (BET-0004), are usually run one board per group of two or three students. If the whole class runs the same experiment in one session, you need a board for every group; if groups rotate through different experiments, you need one of each board per station. Send your practical syllabus with the number of student groups per session and ask for the codes to be mapped against it, so the quantities follow from the timetable.
Ask for the experiment manual and a sample set of results or curves. If the manual sets out the procedure, the theory and the expected readings, the board will teach; if it is only a wiring diagram, it will not. Check also whether test points are brought out to labelled sockets and whether meters are built in or assumed. Sending your practical list and asking for the codes to be mapped against it usually shows both gaps and duplication faster than reading five pages of listings.
It covers foundation-level work: diode, transistor, FET, DIAC, TRIAC and LDR characteristics; a rectifier trainer and a Zener diode voltage regulator; Hartley, Colpitts and Wien bridge oscillators and multivibrators; BJT amplifiers and an emitter follower; Maxwell and Hay bridges, dielectric constant and Lissajous patterns; and digital logic such as a BCD adder and subtractor and an arithmetic and logic unit. Later-year work sits in the separate Digital Analog, Microprocessor, Embedded System, Communication and RF, Power Electronics and Instrumentation trainer ranges.
These boards are handled by successive year groups, so ask two things. First, whether the active devices are socketed, so a blown transistor can be replaced without soldering. Second, whether a spares kit can be supplied with the order. Confirm the supply voltage, frequency and plug type for your country, and for the electrical safety standard the boards are built to, contact us for the latest copies of the relevant certificates. The electrical safety demonstrator (BET-0001) is worth adding to any teaching lab order.
