Product Highlights

• Easy to use -  With the PIE 422Plus you can check & calibrate all your thermocouple instruments, measure thermocouple Sensors, and calibrate 4 to 20 milliamp instruments. Automatic indication of connections on the display for simple hookups. Calibrate all your 4 to 20 milliamp instruments with the built-in milliamp calibrator.
• Take it 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 dark areas with the backlit display.
• Calibrate directly in temperature (°C & °F) - Stop carrying around a millivolt source and thermocouple tables. The PIECAL 422Plus 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.
• Checkout all your 4 to 20 mA loops & instruments - With the built-in milliamp calibrator you can check, calibrate and measure all your current signal instruments in a 4 to 20 milliamp DC loop. It can be used at any access point in your loop. Source & Read 0.000 to 24.000 mA, Simulate a 2 Wire Transmitter or use the PIE 422Plus to simultaneously power your 2 Wire RTD Transmitter and measure its output while simulating the RTD sensor input. Powers HART™ transmitters with built-in 250 ohm resistor simplifying hookups with HART communicators.
• Troubleshoot loop problems - Quickly diagnose ground fault and current leakage with the patented loop diagnostic technology (US Patent# 7,248,058).
• Fast calibration 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, 9, 10, 15, 20, 25, 30 and 60 seconds.
• Calibration Lab Accurate & Stable - The internal cold junction thermistor is accurate to ±0.05°C and is traceable to NIST. The Actual Size 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. It has an extremely stable voltage reference and low drift components which make it more accurate than most other handheld & benchtop thermocouple calibrators.
• Perform Heat Treating Uniformity Surveys and System Accuracy Tests - The PIECAL 422 meets or exceeds the requirement of AMS 2750 as a Field Test Instrument.
• Measure thermocouple sensors - Connect your thermocouple and the PIE 422Plus measures the probe in degrees C or F. Secondary display shows the millivolt value corresponding to the thermocouple temperature.
• Evolutionary design - PIE 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 422Plus 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.
