The Practical Instrument Electronics (PIE) Model 525 Dual T/C & RTD calibrator is the best on the market. It provides direct temperature calibration to all types of instruments such as transmitters, recorders, controllers, alarms, data acquisition, and computer systems. Also, the Model 525 reads RTD & T/C outputs and displays temperature. It is compatible with pulsed systems and transmitters (like the Rosemount 3144). The PIE 525 has a PATENT PENDING feature for trouble shooting. The Auto Detection of 2, 3, or 4 wire connections will tell you if you have the wires correctly connected or misconnected. You can also select Auto Stepping which offers selectable step sizes and time in-between steps. The Model 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.
