• Easy to use -With the PIECAL 422 you can check & calibrate all your thermocouple instruments and  measure thermocouple sensors.
• 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 422 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 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. The PIECAL 422 measures the thermocouple 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.
• 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 422 improves upon other brands by including a rubber boot,  tilt  stand,  backlit  display  with  larger  digits,  rugged switches and a battery compartment for fast battery changes.

Advantages of the PIECAL 422 over the Altek 422

Automatic Stepping & Ramping Larger Display with Backlight Easy viewing in dark locations More Resistant to Accidental Damage Rubber Boot and Stronger Switches Separate Battery Compartment No more removing housing with screwdriver to replace batteries Calibration seals remain intact Easily Change Thermocouple Types Reconfigure without resetting calibrator Verify Cold Junction Temperature & Output Secondary display of compensated millivolt setting and cold junction temperature
