The Practical Instrument Electronics Model 512S RTD Calibrator provides direct temperature calibration to all types of instruments such as transmitters, recorders, controllers, alarms, data acquisition, and computer systems. Also, the Model 512S reads RTD outputs and displays in temperature. It is compatible with pulsed systems and transmitters (like the Rosemount 3144.) 2, 3, or 4 wire connections are detected automatically. The Model 512S is a superior replacement for decade boxes, eliminating the need for lugging around large equipment and the possibility of misreading RTD tables.

Select from 8 RTD types to source/read in °C or °F with 0.1 ° resolution. Or, select Ω for direct resistance source/read capability.
Use the EZ-Check Switch to quickly switch between three stored temperature / Ω outputs. The Auto step mode allows the end user to select the high, mid and low test points along with step size and time. 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 512S offers the highest performance and functions in its class by exceeding the accuracy and functions of many higher priced RTD calibrators. It is a low cost solution for checkout and calibration of all RTD instruments in the field, shop or control room.
