Thermocouple and Millivolt Multifunction Handheld Calibrator

Multifunction Thermocouple Calibrator

Item# CL300A

Multifunction Thermocouple Calibrator CL300A CL300A
  • Please refer to the CL940-Series for possible replacement.

  • Measures Inputs from 10 Common Thermocouple Types plus mV
  • Accepts Miniplugs and Bare Wires
  • Simple Decade Control of Output
  • 3 Setpoints for Each Thermocouple Type
  • Min/Max Recall
  • Input Protection to 240 Vac
  • Certificate of Calibration

The CL300A multifunction thermocouple/mV calibrator combines high accuracy with ease of use. Its accuracy of ±0.3°C (±0.5ºF) includes all errors, at resolutions of 0.01°C or °F in measure mode and 0.1°C or °F in source mode. Features include min/max recall in measure mode, 3 setpoints per thermocouple type, a large knob for decade control of the output in source mode, and compatibility with both bare-wire and miniplug inputs.
