• Easy to use
With the PIECAL 322-1 you can check & calibrate all
your thermocouple instruments and measure
thermocouple Sensors. Automatic indication of
connections on the display for simple hookups.
• Take it without into the shop, plant or field
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.
• Calibrate directly in temperature (°C & °F)
Stop carrying around a millivolt source and
thermocouple tables. The PIECAL 322-1 works with
the T/Cs you use including types J, K, T & E. 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 EZ-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. Select the step time to
match your system from 5, 6, 7, 8, 10, 15, 20, 25, 30
and 60 seconds.
• 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.
• Measure Thermocouple Sensors
Trouble shoot sensor connections and find broken wires or high resistance junctions. Connect
your sensor and the PIECAL 322 automatically measures the thermocouple in degrees C or F.
