With the CL542-PLUS you can
check and calibrate all your
thermocouple instruments and
measure thermocouple sensors.
Calibrate Directly in
Temperature (°C and °F)
Stop carrying around a millivolt
source and thermocouple tables.
The CL542-PLUS works with the
thermocouples you use including
Types J, T, E, K, R, S, B, N, G, C,
D, L (J-DIN), U (T-DIN) and Platinel
II. Easily set any value quickly to
within 0.1° with the adjustable digital
potentiometer “DIAL” plus store any
three temperatures for instant recall
with the check switch.
Calibrate Quickly with
Automatic Output Stepping
Choose between 2, 3, 5, 11 and 21
steps to automatically increment the
output in 100%, 50%, 25%, 10% or
5% of span.
Compatible with All
Process Instruments
Connect directly to the
thermocouple inputs of
smart transmitters,
PLCs, DCS and
multichannel recorders
and verify their outputs
or displays. Carry it
without worry—it comes
protected with a rubber
boot and rugged, low
profile switch. Easy to
operate even in the dark
areas of the plant with
the backlit display.
