Automated Thermocouple Calibrator

• Easy to use

With the PIE 422 you can check and calibrate
all your thermocouple instruments and measure
thermocouple sensors.

• Take it into the shop, plant or field

Carry it without worry - it comes protected with a rubber boot and
rugged, low profile switches. 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 PIE 422 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.

PIECAL 422

•

Fast calibration with automatic output stepping

Choose between 2, 3, 5, 11 steps and ramp 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, 9, 10, 15,
20, 25, 30 and 60 seconds.

• Compatible with ALL process instruments

No competitor’s calibrator is compatible with as many process
instruments! Connect directly to the thermocouple inputs of transmitters,
PLCs, DCS & multichannel recorders to verify their outputs or displays.

• Measure thermocouple sensors

Trouble shoot sensor connections and find broken wires or corroded
connections. Connect your thermocouple and the PIE 422 measures
the probe in degrees C or F. Secondary display shows the millivolt
value corresponding to the thermocouple temperature as well as
the cold junction temperature measured by the calibrator.

Actual Size

• Calibration Lab Accurate & Stable

The internal cold junction thermistor is accurate to ±0.05°C and is traceable to NIST. The sensor is thermally
bonded to an isothermal mass which includes brass blocks with screw terminals for connection of bare
thermocouple wires along with a miniature thermocouple connector for fast connections. The circuitry uses an
extremely stable voltage reference and low drift components which make the PIE 422 more accurate than most
other handheld and benchtop thermocouple calibrators.

• Perform Heat Treating Uniformity Surveys and System Accuracy Tests

The PIE 422

can meet the requirements of an AMS 2750 Field test instrument when certified by an accredited lab.

• 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 PIE 422 improves upon other brands by including a rubber
boot, tilt stand, backlit display with larger digits, rugged switches & a battery compartment for fast battery changes.

* PIECAL Calibrators are not manufactured or distributed by Fluke Corp or Altek Industries Inc, manufacturers of Altek Calibrators.

Connections

Simulating or reading thermocouples requires the use of
thermocouple or extension grade thermocouple wire.
Plug thermocouple wires into the miniature thermocouple jack
or place bare thermocouple wires onto the brass block under
the screws.

The PIECAL 422 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.
