The Chub-E4 has four inputs for reading four different sensors simultaneously, and we’ll configure those inputs in any of three different ways according to your preference. Choose four channels of thermocouple inputs, four channels of PRT/thermistor inputs, or two channels of each. With this thermometer, reading thermocouples, PRTs, and thermistors accurately from the same device is no problem.

100-ohm, 25-ohm, or 10-ohm PRTs and RTDs are read using ITS-90, IEC-751 (DIN), or Callendar-Van Dusen conversion methods. Typical accuracies include ±0.004 °C at –100 °C and ±0.009 °C at 100 °C. Thermistor readings are converted using the Steinhart-Hart polynomial or standard YSI-400 curve and are as accurate as ±0.0025 °C at 25 °C with resolution of 0.0001 °.

Thermocouple inputs read all the common thermocouple types, including B, E, J, K, N, R, S, T, and Au-Pt, and allow you to choose between internal and external reference junction compensation. Typical accuracy for a type J thermocouple at 600 °C is ±0.35 °C using internal reference junction compensation and not including the thermocouple. (Support for C and U type thermocouples is available. Download the application note Using Fluke Calibration Readouts with Tungsten-Rhenium and other Thermocouples.)
