What Is the Thermistor Characteristics Apparatus Used For?
A thermistor is a semiconductor resistor whose resistance changes strongly with temperature; in a negative temperature coefficient (NTC) thermistor the resistance falls as the temperature rises. This apparatus lets undergraduate physics and electronics students measure that change: the thermistor is warmed in the oven, the temperature is read on the thermometer, and at each temperature the voltage across the thermistor and the current through it are noted, so that its resistance follows from R = V/I. Plotting resistance against temperature shows the falling curve, and plotting the natural logarithm of resistance against the reciprocal of absolute temperature gives a near straight line whose slope is used to find the thermistor’s material constant.
Keep the current low so that the thermistor is not heated by its own current, and let the oven temperature settle before each reading. Take readings while the oven heats and again as it cools, then compare the two sets.
What to Specify When Ordering
- Quantity — the minimum order is 10 units; plan one for each student group running the experiment.
- Companion temperature experiments — a thermocouple or platinum resistance thermometer can be added to the same enquiry, as listed below.
- Delivery details — destination country and city or port, preferred delivery terms (for example FOB or CIF) and any tender reference.
Frequently Asked Questions
What experiment does this apparatus perform?
It plots the negative resistance coefficient characteristics of a thermistor, showing how its resistance falls as the temperature rises.
What is included in the apparatus?
A regulated DC power supply, two meters for voltage and current, one thermistor, an oven and a thermometer, with the supply, meter and thermistor connections brought out to terminals.
How large is the unit?
It measures 10 x 8 x 5 inches.
Who manufactures the apparatus?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes it at its works in Ambala, Haryana, India, and quotes for it directly.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a physics lab equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The apparatus is assembled in JLab’s own works rather than bought from a trader, so colleges, universities, dealers and importers can buy it factory-direct; each unit is visually inspected before dispatch, and repeat orders and replacement parts are handled by the manufacturer. JLab exports worldwide and ships to every region — Iraq in the Middle East, Botswana in Southern Africa, Japan in East Asia, Kyrgyzstan in Central Asia and Bhutan in South Asia are some examples. For tender enquiries, see the JLab lab tenders page.
