Thermistor Characteristics with power supply and 1 digital meter (C.R.) Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12172
Indian Lab Suppliers supplies the Thermistor Characteristics with power supply and 1 digital meter (C.R.) (Product ID: 12172) as part of its electronics engineering lab equipment range. It is a self-contained set-up for plotting how the resistance of a thermistor changes with temperature.
Quick Answer
The thermistor sits in an electrically heated oven with a 0–110 °C thermometer. A band switch selects a 1 V, 2 V or 5 V DC supply (10 mA), and a 3½-digit digital milliammeter on its 2 mA range reads the current, so resistance follows from R = V/I at each temperature. Students draw the resistance-temperature curve, find the temperature coefficient from the graph and compare it with the theoretical value. The oven and thermometer get hot and the thermometer is glass, so handle both with care.
