With the Practical Instruments (PIE) PIECAL 525B automated T/C and RTD calibrator, you can check and calibrate all your thermocouple and RTD instruments and measure temperature 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 thermocouple instruments to 0.1 & 0.01 °F & °C The PIE 525B 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). Or calibrate from -13.0000 to +80.0000 mV. Calibrate RTD instruments to 0.1 & 0.01 °F & °C

Stop carrying around a decade box and RTD resistance tables. The 525B works with the RTDs you use including Platinum 10, 50, 100, 200, 500 & 1000 Ohm (alpha = 3850), Platinum 100 Ohm (alpha = 3902, 3916, 3926), Copper 10 & 50 Ohm, and Nickel 120 Ohm. Or calibrate from 0.000 to 400.000 and 0.00 to 4000.00 Ohms. For RTDs the fixed or pulsed sensor current is measured by the calibrator.

Fast calibration with automatic output stepping Easily set any value quickly to within 0.1° or 0.01° with the adjustable digital potentiometer "DIAL" plus store any three temperatures for instant recall with the EZ-CHECK™ switch. Choose between 2, 3, 5, 11 steps and ramp to automatically increment the output in 100%, 50%, 25%, 10% or 5% of span. Select step time from 5, 6, 7, 8, 9, 10, 15, 20, 25, 30 & 60 seconds.

Compatible with ALL process instruments: No competitor's calibrator is compatible with as many process instruments! Connect directly to the temperature inputs of transmitters, PLCs, DCS & multichannel recorders to verify their outputs or displays. RTD simulation works with older instruments with fixed excitation currents and newer multichannel instruments that switch the excitation current between input channels.

Measure thermocouple & RTD sensors: Trouble shoot sensor connections and find broken wires or corroded connections. The PIE 525B measures probes to 0.1 or 0.01 °C or °F. Secondary display shows the millivolt or resistance value corresponding to the sensor temperature as well as the junction temperature measured by the calibrator. Trouble shoot sensor connections and find broken wires with patented technology. Connect your two, three or four wire RTDs and the PIE 525B automatically detects the connections.

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 525B more accurate than most other handheld and benchtop thermocouple calibrators.

Perform Heat Treating Uniformity Surveys and System Accuracy Tests: The PIE 525B meets or exceeds the requirement of AMS 2750 as a Field Test Instrument.

Evolutionary design: The PIE 525B includes a rubber boot, tilt stand, backlit display with larger digits, rugged switches & a battery compartment for fast battery changes.

12 RTD and 14 T/C types, high accuracy with .01 Degree resolution. Includes RTD wire kit, mV leads, rubber boot, Hands-Free carrying case and FREE NIST Traceable Certificate of Calibration.
