The Practical Instrument Electronics (PIE) 530 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 530 calibrator incorporates all of this knowledge and experience and combines it into one superior 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 530 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 530 can source and read current in the process loop and simulate, power and measure 2-wire transmitters. It can read voltage to 30.00 VDC with over 4X over range ability.
