PIECAL 520B & 521B
• Easy to use
With the PIECAL 520B or 521B you can check & calibrate all
your thermocouple instruments. Connect via a miniature
thermocouple jack on the top end of the source. Use your own
thermocouple wire connectors or order one of the wire kits for easy
operation out of the box.
• Take it into the shop, plant or field
Carry it without worry - protect it with an optional rubber boot and
rugged, low profile switch. Easy to operate even in the dark areas of the
plant with the backlit display.
• Source one or fourteen thermocouple types
Choose the PIECAL 520B if you have only one type of
thermocouple connected to your instruments or the PIECAL
521B if you have multiple types of thermocouples.
Thermocouple Source
• Calibrate directly in temperature (°C & °F)
Stop carrying around a millivolt source and thermocouple
tables. The PIECAL 520B/521B works with the thermocouples
you use including types J, K, T, E, R, S, B, N, G, C, D, L
(J-DIN), U (T-DIN) and P (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 EZ-CHECK™ switch. Or calibrate from -13.000 to
+80.000 mV.
• Compatible with ALL process instruments
No competitor’s calibrator is compatible with as many
process instruments! Connect directly to the thermocouple
inputs of smart transmitters, PLCs, DCS and multichannel
recorders and verify their outputs or displays. Works with
older instruments and newer multichannel instruments that
switch between input channels.
• Evolutionary design
PIECAL Calibrators are designed and built by members of the
same team that designed and built the calibrators manufactured
by Fluke* under the Altek* label. The PIECAL 520B/521B
improves upon other brands by including backlit display with
larger digits, rugged switches and a battery compartment for
fast battery changes. Add an optional rubber boot with tilt
stand for extra protection on the plant floor or in the field.
* PIECAL Calibrators are not manufactured or distributed by Fluke
Corp or Altek Industries Inc, manufacturers of Altek Calibrators.

Simulating thermocouples requires the use of thermocouple
or extension grade thermocouple wire.
Plug thermocouple wires into the female miniature
thermocouple connector mounted in the top end of the housing.
The PIECAL 520B/521B has two banana jacks mounted in
the top end of the housing. These are not temperature
compensated and are to be used only for millivolt signals.
