The PIE 525 Plus Thermocouple & Milliamp Calibrator 3-in-1 thermocouple, RTD, and full function milliamp calibrator. The 525 Plus includes a full function diagnostic milliamp calibrator that sources and reads 0.000 to 24.000 mA, simulates two wire transmitters, powers & measures transmitters with its internal 24V supply, has a built-in 250 ohm resistor for HART compatibility and PIE's patented Ground Leak Detection. Competitive calibrators allow you to calibrate temperature transmitters but don't have the ability to test other instruments in a 4 to 20 mA loop. The two parts of the calibrator sources and reads both 14 thermocouples types and 12 RTD types to 0.01°F & °C.
The milliamp, thermocouple & RTD sections were designed with state of the art components that are the most accurate and stable found in a handheld calibrator. The internal cold junction is accurate to ±0.05°C and is traceable to NIST. These instruments measure RTD sensors with a pulsed excitation current that is too fast for many calibrators to lock onto which causes errors in calibration. The PIE 525Plus has unique circuitry designed to accurately calibrate smart and multivariable transmitters, PLC inputs, and multichannel recorders.
