The OMEGA CL20 series calibrator/
thermometers simulate, measure and
record RTD, ohm, thermocouple and
thermistor signals–all in one meter.
They outperform the competition in the
lab and on the factory floor with 0.3°C
(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 costeffectiveness,
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 Celsius and
Fahrenheit. This convenient display
takes the guesswork out of which
sensor has been selected, displaying
°C or °F and operating mode.
Programming a CL20 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 program 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 simply enter the output
value and calibrate.
The ramp function of Models CL25 and
CL27 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.
No matter what thermocouple type is
used, one of these meters can handle
it. Features to choose from include 100
ohm and 1000 ohm RTD and 2252 ohm
thermistor 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.). OMEGA 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.
