The CL510A Series can check and
calibrate all your RTD instruments.
Take it into the shop, plant or field
without worry. It’s easy to operate
even in the dark areas of the plant
with the backlit display. Stop
carrying around a decade box
and RTD resistance tables, with the
CL510A you can calibrate directly in
temperature (°C and °F). Choose
between a single RTD type model,
CL510A-1 (Pt100, 0.00385), or a
CL510A-10 for multiple RTD types.
The CL510A-10 works with a wide
variety of RTD curves including
Platinm 100 (alpha = 3850,
3902, 3916, 3926) and 1000
(alpha = 3850, 3750) Ω, Copper
10 and 50 Ω, Nickel 100 and 120 Ω.
Easily set any value quickly to
within 0.1° with the adjustable
digital potentiometer "DIAL".
Connect directly to RTD inputs of
smart transmitters, PLCs,
controllers and multichannel
recorders and verify their displays.
