The OMEGA® CL20 handheld
calibrators/thermometers simulate,
measure, and record RTD, Ω,
thermocouple, and thermistor
signals—all in one. Featuring an
accuracy of 0.3ºC (0.5ºF) at ambient
temperatures from
18 to 28ºC (64 to 82ºF) and a
host of powerful keypad functions,
these low-cost meters outperform
the competition.

The 5-digit LCD indicates all
active functions and has 0.1ºC/
ºF resolution. Operating mode and
sensor type are also displayed.

Programming is a snap. The user
can enter setpoints directly on the
keypad or from an outside source.
Ten memory locations allow for
instant recall of any programmed
value, and the step function lets the
user navigate the test points
with the push of a button.

Simulates, Measures,

and Records Thermocouple,

RTD, Thermistor, and Resistance

Signals—All in One Meter!

The ramp function of the
CL25 and CL27 makes calibration
easy. When the user enters the
upper limit, lower limit, and step
size, the meter automatically ramps
between the limits. Ramping can
also be performed manually.

No matter what the input type, one
of these meters can handle it. The
possibilities include 100 and 1000 W
RTDs and 2252 W transistors.

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 (NIST). OMEGA
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 (0.5°F) 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.
