Description

Description

The trodeks CL20 series calibrator/thermometers simulate, measure andrecord RTD, ohm, thermocouple andthermistor signals–all in one meter.They outperform the competition in thelab and on the factory floor with 0.3°C(0.5°F) accuracy and in ambienttemperatures from 18 to 28°C(64 to 82°F).

This powerful handheld meter allowsthe user to calibrate in the field as wellas in the lab and offers many additionalfunctions that translate into costeffectiveness,increased productivityand long-lasting versatility andreliability.

The 5-digit LCD display indicates allactive functions and allows users tohave 0.1° resolution in both Celsius andFahrenheit. This convenient displaytakes the guesswork out of whichsensor has been selected, displaying°C or °F and operating mode.

Programming a CL20 series calibratoris a snap. The keypad allows directentry of calibrator setpoints. Setpointscan also be entered from an outsidesource by inputting temperatures orvoltages through the thermometermode. There are no reprogramminghassles. The program won’t be lostwhen the meter is shut off. All valuesare retained and can be retrieved forfast repeat use.

These calibrators feature 10 memorylocations that can instantly recall anyprogrammed value, and the stepfunction lets the user run through thetest points at the push of a button. Thisefficient feature saves time by allowingthe user to simply enter the outputvalue and calibrate.

The ramp function of Models CL25 andCL27 makes calibrating switch andalarm setpoints quick and easy. Byentering the upper limit, lower limit andstep size, the meter automaticallyramps between the limits. There is alsoa manual ramp function.

No matter what thermocouple type isused, one of these meters can handleit. Features to choose from include 100ohm and 1000 ohm RTD and 2252 ohmthermistor capabilities.

 
Need to comply with ISO-9000 reporting specifications? These meters can help! All conform to the temperature/voltage tables of the National Institute of Standards and Technology (N.I.S.T.). trodeks provides a free NIST Traceable Certificate of Calibration for your records. Since ISO-9000 requires that calibration be done at the equipment site, these meters are a perfect choice. With 0.3°C (0.5F°) accuracy in an ambient temperature range of 18 to 28°C (64 to 82°F), you’re not confined to the lab. Take it everywhere. The ABS plastic case protects it from dust and dirt.
