The PIE 235 Process Voltage Calibrator checks, calibrates and measures voltage instruments. The 20V range has an extended span of up to 24V giving you a portable source for powering your loops. The PIE 235 has a pH simulator used to verify proper operation of pH devices before you place a probe into a calibrated buffer.
The PIE 235 can easily set any value with the adjustable DIAL plus store any three output settings for instant recall with the EZ-CHECK switch. 2, 3, 5 & 11 steps automatically increment output in 100%, 50%, 25% or 10% of span plus continuous ramp. Set step/ramp time to 5, 6, 7, 8, 9, 10, 15, 20, 25, 30 & 60 seconds.
