The OMEGA CL20 series calibrator/ thermometers simulate, measure and record RTD, ohm, thermocouple and thermistor signals–all in one meter. This handheld meter outperforms the competition in the lab and on the factory floor with 0.5°F accuracy and in ambient temperatures from 18 to 28°C (64 to 82° F).

This powerful handheld meter allows the user to calibrate in the field as well as in the lab and offers many additional functions that translate into cost-effectiveness, increased productivity and long-lasting versatility and reliability.

The 5-digit LCD display indicates all active functions and allows users to have 0.1° resolution in both Fahrenheit and Celsius. This convenient display takes the guesswork out of which sensor has been selected, displaying °F or °C and operating mode.

No matter what thermocouple type is used, this handheld meter can handle it. Features to choose from include 100 ohm and 1000 ohm RTD and 2252 ohm thermistor capabilities.
