Product Description

The Practical Instrument Electronics (PIE) Model 511 simulates RTD resistances into all types of instruments such as transmitters, recorders, controllers, alarms, data acquisition, and computer systems. The Model 511 is a superior replacement for decade boxes, so there is no need to lug a decade box around or be prone to error by reading RTD tables incorrectly. The PIE 511 has better accuracy and functions of many higher priced RTD calibrators
