The PIE 525 T/C & RTD calibrator provides direct temperature calibration to all types of instruments such as transmitters, recorders, controllers, alarms, data acquisition, and computer systems. Also, he Model 525 reads RTD & T/C outputs and displays temperature. It is compatible with pulsed systems and transmitters (like the Rosemount 3144) 2, 3, or 4 wire connections are detected automatically. The Practical Instrument Electronics 525 is a superior replacement for decade boxes, and eliminates the need for lugging around large equipment and the possibility of misreading RTD tables.

Use the EZ-Check™ Switch to quickly switch between three stored temperatures, Ω/mV outputs. It’s easy to customize these values to your application. In read mode, the EZ-Check™ Switch recalls minimum and maximum readings. Store/Clear memory with a press of the EZ-Dial™ Knob.

The Practical Instrument Electronics Model 525 offers the highest performance and functions in its class by exceeding the accuracy and functions of many higher priced T/C & RTD calibrators. It is a low cost solution for checkout and calibration of all T/C & RTD instruments in the field, shop or control room. Contact Practical Instruments Electronics for custom T/C & RTD curves, ranges, or special requirements not provided by the PIE CAL 525.
