The CL-355A is a small, lightweight, portable dry block calibrator,
that offers fast heat-up and
cool-down times with excellent
performance specifications at a wide
operating temperature range. It’s a
good choice for standard bench lab
work or as a portable
field unit.
The unit covers the temperature
range from 5°C (9°F) above ambient
up to 400°C (752°F) using a large
multi-well machined aluminum insert
block as the heat transfer medium to
the sensors under test. The
CL-355A uses the same aluminum
inserts as the CL-740A calibrator.
See CL-700A series at omega.com/
cl-700a for a list of inserts.
This calibrator is designed to
work safely under the following
conditions: ambient temperature
range: 5 to 40°C (9 to 104°F),
up to 95% relative humidity,
non-condensing.
