The 1502A is calibrated digitally using the front-panel buttons. You never have to open the box to calibrate it. It goes where you go and works the way you want it to. There are two more Tweeners for specific applications, including the Model 1503 High Temperature PRT Readout and the Model 1504 Thermistor Readout. If you need more accuracy in a limited temperature range, the Model 1504 Tweener gives it to you as a thermistor readout.
Thermistors are less fragile than PRTs and less likely to be impacted by mechanical shock.
Thermistors are more sensitive to temperature, have faster response times, and come in many shapes for different applications. Log Ware , all three Tweener models may be used for real-time data acquisition. Collect data and analyze it graphically or statistically. Additionally, Tweeners may be used as reference thermometers with our Calibrate -it software. If you want freedom from AC power in the field or on the plant floor, order Model 2502 and we ll install a DC power board in your Tweener.
