Source and measure 8 thermocouple type devices J, K, T, E, C, R, S, and N

The Extech 433201 Thermocouple Calibrator Thermometer sources and measures 8 thermocouple types: J, K, T, E, C, R, S, and N. Displays output in terms of mV or-Degrees F/-Degrees C based on its built-in thermocouple tables. Five stored calibration values for quick calibrations. Oyster case with “flip-up” display is ideal for handheld or benchtop applications.

Complete with 9V rechargeable battery, Type K Thermocouple cable, Copper calibration cable, and 115-Volt AC Adaptor/Charger.

Extech 433201 Thermocouple Calibrator Thermometer Features:

  • One model for multiple thermocouple types with precision output displayed as mV or °C / °F
  • Microprocessor assures maximum accuracy to 0.15% of reading over wide ranges
  • High Accuracy Calibration function simulates precision thermocouple outputs for use in calibrating thermometers, transmitters,controllers or recorders.
  • Complete with universal AC adaptor for Australia

In the ‘Measurement’ mode, a millivolt (mV) signal is accepted from a thermocouple and is displayed on the 4-digit LCD display. A built-in temperature offset feature can be used to compensate for variations found in standard thermocouples. By adjusting the offset, measurement accuracy for a particular thermocouple can be optimized for a particular temperature.

In the ‘Source’ mode, a millivolt signal is output to an external device with the corresponding temperature (according to standard temperature tables) displayed on the LCD display. Preset temperature settings (source mode only) according to thermocouple type are stored in five memory locations for easy recall.

If desired, the meter can be switched to the mV mode where Measurement and Source values can be displayed in millivolts rather than temperature.
