Thermocouple Calibrator

The easy to use 820 allows you to calibrate thermocouples directly in C/F. Quickly set any value to within 0.1C with the adjustable digital potentiometer EZ-DIAL plus recall any 3 temperatures for instant recall with the EZ-CHECK switch. Measure thermocouple sensors; trouble shoot sensor connections to find broken wires or corroded connections. Connect your thermocouple with a mini thermocouple connector and the PIE 820 measures the probes in C/F.

RTD, Resistance Calibrator

With the 820 you can check and calibrate all your RTD instruments and measure RTD sensors and show automatic indication of connections on the display for simple hook-ups. The PIE 820 works with the RTDs you use including Platinum 100 (alpha = 3850, 3902, 3916, 3926) & 1000 (alpha =  3850) Ohm, Copper 10 & 50 Ohm, Nickel 100 and 120 Ohm. Easily set any value quickly to within 0.1C with the adjustable digital potentiometer EZ-DIAL plus store any 3 temperatures for instant recall with the EZ-CHECK switch. Or use like a decade box from 0.0 to 401.0 and from 0 to 4010 Ohms. The 820 is compatible with all process instruments. Connect directly to the RTD inputs of smart transmitters, PLCs, DCS and multichannel recorders and verify their outputs or displays. The 820 works with older instruments with fixed excitation currents and newer multichannel instruments that switch the excitation current between input channels. And with the PIE 820 you can measure RTD sensors and trouble shoot sensor connections to find broken wires. Connect 2, 3 or 4 wires RTDs and the 820 measures the RTD in C/F.

Milliamp Calibrator

Check, calibrate and measure all your current signal instruments in a 4 to 20 milliamp DC loop. Access any point in the loop. Source & Read 0.00 to 24.00 mA. Simulate a 2 wire transmitters or use the 820 to simultaneously power your 2 wire transmitter and measure its output. Source milliamps; calibrate recorders, digital indicators, stroke valves or any instrument that get their input from a 4 to 20 mA loop. Easily set any value quickly to within 0.01 mA with the adjustable digital potentiometer EZ_DIAL or use preset 4.00 mA (0.0%) and 20.00 mA (100.0%) EZ-CHECK settings. The 820 can read loop current, calibrate using loop power and power and measure 2 wire transmitters.

Voltage Calibrator

You can check, calibrate and measure all your voltage, millivolt and pH signal instruments. Source 0 to 10.25 V dc and -10.00 to 80.00 mV. Read DC volts; You can measure from 10.25V, -10.00 to 80.00mV and 0.0 to 60.0 VDC. Use the  PIE 820 to check loop power supplies, I/V converters, 1 to 5 volt signals.

Frequency Calibrator

Calibrate flow meters and frequency instruments; generate zero crossing square wave to check, calibrate and measure all the frequency signal instruments in your facility. Source and read frequencies from 1 to 2000 CPM, 0.01 to 999.00Hz, 0.1 to 9999.9 Hz and 0.001 to 20.000kHz. The PIE 820 has a green LED that flashes in sync with the output frequency. Select a frequency and hold the calibrator up to the optical sensor.

Continuity Checker

Troubleshoot wiring and connection problems; use the built-in continuity checker to look at wiring and connections during installation or to locate shorts. 820 will beep from 0.100 Ohms.
