CL950 hot point® dry block calibrator, shown smaller than actual size with
MDSS41-TC benchtop thermometer (see omega.com) calibrating multiple
thermocouple probes (see omega.com).
OMEGA’s hot point® calibrators
allow calibration of thermocouple
and RTD probes quickly and
easily with accuracy to 0.9°C
(1.5°F). An integral RTD sensor
assures high measurement
accuracy and repeatability. A
built-in microprocessor-based
PID digital controller assures
exceptional stability. Setpoint and
actual temperature are displayed
simultaneously. Temperature can
be set in one-degree increments
from 22°C (40°F) above ambient
to 482°C (900°F).
The CL900 calibrator accepts a
variety of standard and metric
optional inserts which are available
in 4 and 6" depths and for probe
diameters from 1⁄8 to 3⁄8". An undrilled
insert is also available. The CL900
comes complete with a 1⁄4" diameter,
6" deep insert well and insert block
tongs. Additional inserts can be
ordered separately as required for
other diameter probes. 6" depth
inserts are used for probes 7" and
longer; 4" depth inserts are used for
probes 5" and longer.
The CL950 calibrator features a
built-in well with 5 ports sized to
accommodate a 1⁄16, 1⁄8, 3⁄16, and
two 1⁄4" diameter probes. The multi-
port design allows for the use of a
calibrated or NIST-traceable probe
and meter to be used as a standard
while calibrating other probes.
The 5 port design also allows for
calibration of more than 1 probe at
a time, and eliminates the need for
separate insert wells.
Caution: To avoid fire hazard or damage to
your calibrator, always allow your calibrator
to cool down to ambient temperature before
returning to storage.
