PIECAL 525B

The PIECAL 525B from Practical Instrument Electronics (PIE) , which replaces the PIE Model 525. This moves their Dual Thermocouple & RTD calibrator to the rugged Evolution style enclosure with a rubber boot and tilt stand for bench use.

The PIECAL 525B combines features from the PIECAL 311 Automated RTD Calibrator & PIECAL 422 Automated Thermocouple Calibrator.

Other features include:

  • 14 Thermocouple types 

  • RTD types for Platinum 10, 50, 200 & 500 Ohm for the 1.3850 (IEC 751/DIN) curve

  • More accurate & stable cold junction compensation 
    NIST Traceable Cold Junction Sensor in isothermal block

  • Large, backlit display 
    Shows millivolts and cold junction temperature while displaying thermocouple temperature. 
    Shows ohms while displaying RTD temperature

  • Troubleshoot RTD Sensors & Instruments
    Automatic detection of 2, 3 or 4 wire connections indicates when individual wire connections are open. Verify proper instrument operation by measuring the excitation current

  • Calibrate Thermocouple instruments to 0.1 & 0.01 °F & °C
    Types J, K, T, E, R, S, B, N, G, C, D, L (J DIN), U (T DIN) & P (Platinel): -13.000 to 80.000 mV

  • Calibrate RTD instruments to 0.1 & 0.01 °F & °C
    Pt 10, 50, 100, 200, 500 & 1000 Ohm (3850)
    Pt 100 Ohm (alpha=3902, 3916, 3926)
    Cu 10 & 50 Ohm and Ni 120 Ohm

  • Calibrate with Confidence
    Resolution to 0.01 °F & °C; Accurate to 0.2°
    Cold Junction Sensor Accurate to 0.05°C

  • Perform Heat Treating Surveys & Accuracy Tests
    Meets or exceeds the requirement of AMS 2750 as both a Secondary Standard Instrument and as a Field Test Instrument

  • Troubleshoot RTD Sensors & Instruments
    Automatic detection of 2, 3 or 4 wire connections indicates when individual wire connections are open. Verify proper instrument operation by measuring the excitation current.

  • Easily find trip points with
    Instantly select three outputs with EZ-CHECK switch
    Faster Calibrations
    two speed EZ-DIAL knob & Automatic Stepping

  • Easily Change Thermocouples and RTD Types & Scale
    Double click to select Thermocouples or RTD type & °F & °C

  • Use in the Plant, Field or Shop
    Includes Rubber Boot and mV Test Leads
    Low profile switches resist accidental damage
    Brass screws for Thermocouple wires plus mini Thermocouple socket

  • Easy-to-Read Display
    Turn on the backlight to read in dark areas of the plant

  • Simple “No Tool” Battery Changes
    Four inexpensive “AA” batteries

  • Verify Resistance, Cold Junction Temperature & Output
    Secondary Display of Resistance for RTDs and compensated millivolt setting and cold junction temperature for T/C.
