The Practical Instrument Electronics (PIE) 531 is the result of 30+ years of experience manufacturing and designing calibrators for the process control industry. Almost all of the Fortune 500 manufacturers use calibrators designed by our engineers. The PIE 531 calibrator incorporates all of this knowledge and experience and combines it into one small but powerful product. It has simple, easy to use controls featuring a large high contrast display with easy visibility without the need for contrast adjustments.
The PIE 531 is designed to be a tool with all the practical functions required to get the job done easily without the confusing extras or reading through a complicated manual. The PIE 531 can source and read current in the process loop and simulate, power and measure 2- wire transmitters. It fits in your pocket or you can clip in on your belt.
