Model CL27EC Shown

The OMEGA CL20EC Series calibrator/thermometers simulate, measure and record RTD, ohm and thermocouple signals all in one meter. They outperform the competition in the lab and on the factory floor with 0.3°C accuracy. The 5-digit LCD display indicates all active functions and allows users to have 0.1° resolution in both Celsius and Fahrenheit. This convenient display takes the guesswork out of which sensor has been selected, displaying °C or °F and thermometer or calibrator mode. Programming a CL20EC series calibrator is a snap. The keypad allows direct entry of calibrator setpoints. Setpoints can also be entered from an outside source by inputting temperatures or voltages through the thermometer mode. There are no reprogramming hassles. The programme won't be lost when the meter is shut off. All values are retained and can be retrieved for fast repeat use. These calibrators feature 10 memory locations that can instantly recall any programmed value, and the step function lets the user run through the test points at the push of a button. This efficient feature saves time by allowing the user to just enter the output value and calibrate. The ramp function of Models CL25EC and CL27EC makes calibrating switch and alarm setpoints quick and easy. By entering the upper limit, lower limit and step size, the meter automatically ramps between the limits. There is also a manual ramp function. Because these meters combine so many functions, they eliminate the need for expensive, single purpose meters. All temperature simulating and measurement can be done with one meter, instead of using one for thermocouples, and another for RTD applications. No matter what thermocouple type is used, one of these meters can handle it. Features to choose from include 100 and 1000 ohm RTD, and 2252 thermistor capabilities.
