Quick answer. With fifty-one records and many subjects repeated, the first decision is one code per experiment, each with its calibration reference. Displacement by linear variable differential transducer appears under IT-0009, IT-0045 and IT-0052, and temperature in six places, so ask which single code covers each subject on your syllabus and check you are not buying the same experiment twice. Then ask, for every transducer code, what known input is supplied to calibrate against - a micrometer or slip gauges, masses or a dead-weight tester, a temperature bath or reference thermometer - because a trainer without one can demonstrate a sensor but cannot teach calibration.
Fifty-one records are catalogued here across six pages, numbered IT-0001 to IT-0052. They cover three distinct subjects: transducers and measurement, classical control systems, and programmable logic controllers with their industrial applications. One thing to know before you read any further: several subjects appear under more than one code in this listing, with displacement measurement by linear variable differential transducer appearing three times and temperature measurement in six places. Quote codes rather than names when you enquire, ask for the specification against each code, and check you are not buying the same experiment twice. The list of overlaps is set out near the end of this page.

A measurement trainer with no reference standard can demonstrate a sensor but cannot teach calibration, which is usually the point of the experiment. For each transducer code ask what known input is supplied to calibrate against: a micrometer or slip gauges for displacement, a set of masses or a dead-weight tester for load and pressure, a temperature bath or reference thermometer for temperature. Then ask whether that reference is itself calibrated and traceable.
Beyond that, the questions differ by sensor type:
Two codes in this group name themselves simulators (IT-0029 and IT-0030), so ask of every control trainer whether the plant is physical hardware or an electronic analogue of one, since the two teach different things and cost differently. Then ask:
Four PLC trainers are listed (IT-0016 to IT-0019) and six application modules (IT-0020 to IT-0025). Programmable logic controller trainers arrive unusable more often than any other kind, almost always for the same three reasons. Settle all of these in writing before ordering:
Where an application module drives a real motor, conveyor or heater (IT-0023, IT-0024, IT-0025), ask about the supply, the earthing, the guarding of moving parts and an emergency stop within the student's reach.
Ask the supplier which single code covers each subject for your syllabus, because this listing offers several of them more than once and the differences are not stated:
The experiment manual with expected readings and worked calculations; the quantity per student group; which instruments each experiment assumes, since almost all of them need a meter and most need an oscilloscope; spares, in particular strain gauges, lamps and sensors; the supply voltage, frequency and plug type for your country; and the warranty. Product names in this range carry the phrase "For Instrumentation Electric Labs", which is a naming convention on this site rather than a specification. Any performance figure quoted is confirmed in writing on the quotation; ask for its basis.
Measurement at mains level, machines and metering are under Electrical Engineering Trainers and Power and Instrumentation Lab. Converter and drive circuits are under Power Electronics Trainers. Amplifier and filter foundations are under Basic Electronics Trainers, conversion and logic under Digital and Analog Trainers and Kits, microcontroller-based instruments under Embedded System Trainers, physiological measurement under Bio Medical Technology, and instruments themselves under Testing and Measuring Lab Trainers. Parent range: Electronics Lab Trainer Kits.
Send your instrumentation and control practical list and ask for a quote that names, against each code, the reference standard supplied for calibration and, for the PLC items, the controller model, the software licence and the cable. For example LVDT Trainer (IT-0009) and Load Measurement Using Strain Gauge Kit (IT-0047), eight benches, with the calibration references confirmed in writing. Contact Ray Export for prices, manuals and lead times.
Several subjects appear more than once with no stated difference. Displacement by LVDT: IT-0009, IT-0045 and IT-0052, with IT-0045 listed twice. Temperature: IT-0008, IT-0033, IT-0034, IT-0048 and IT-0049, plus IT-0023 under PLC control. Pressure: IT-0013 and IT-0046. Load and strain: IT-0010 and IT-0047. Position control: IT-0028 and IT-0036. Relay control: IT-0011 and IT-0038. Potentiometric error detector: IT-0012 and IT-0031. Compensation: IT-0027 and IT-0039. PID control: IT-0026 and IT-0029. Light: IT-0006, IT-0043 and IT-0050. Ask which single code covers each subject.
For the strain gauge trainers (IT-0010, IT-0047), ask the bridge configuration and whether quarter, half and full bridge can all be tried, the excitation voltage, the amplifier gain, and whether a shunt calibration facility is provided. Ask whether spare gauges are available, since a gauge damaged by overload cannot be repaired. For the LVDT trainers (IT-0009, IT-0045, IT-0052), ask the stroke range and linearity, whether the oscillator and phase-sensitive demodulator are accessible at test points, and whether the core can be positioned by a micrometer so output can be plotted against known displacement.
For the thermocouple trainer (IT-0048), ask whether cold junction compensation is provided and whether it is visible to the student, because a thermocouple experiment that ignores the reference junction gives wrong readings, and understanding why is part of the lesson; ask which thermocouple types are supplied. For the resistance thermometer (IT-0049), ask whether two, three and four-wire connection can all be shown, since lead resistance is the whole difficulty with this sensor, and whether self-heating can be shown by varying the excitation current. For both, ask what temperature reference is supplied.
Ask of every one. IT-0029 and IT-0030 name themselves simulators, and a physical plant and an electronic analogue of one teach different things. Ask whether both step and frequency response can be measured, whether controller gains and time constants are adjustable, and how the response is recorded, since a step response on a slow plant cannot be read off a conventional oscilloscope. For the position and servo trainers (IT-0028, IT-0036, IT-0037, IT-0040, IT-0042), ask the motor rating, feedback device, whether load can be varied, and whether the motor guard is supplied.
Almost always for three reasons, so settle them in writing for IT-0016 to IT-0019. First, which make and model of controller is fitted, and is it a current product that can still be bought and serviced? Second, which programming software, which version and what licence: included or not, how many seats, node-locked or floating, and does it run on your laboratory computers' operating system? Third, which programming cable or interface, and do its drivers work on your machines? A serial-only cable on computers without serial ports stops the laboratory before it starts.
Ask explicitly, because the listing does not say whether the water level, elevator, traffic light, temperature, conveyor and DC motor speed modules fit all four trainers or only one, or whether the cabling between module and trainer is included. Ask too whether example programs come in editable source form, so students can modify them rather than only run them, and whether a wiring and programming manual is included. Where a module drives a real motor, conveyor or heater (IT-0023, IT-0024, IT-0025), ask about the supply, earthing, guarding of moving parts and a reachable emergency stop.
