PIE 334 mA Loop Calibrator

The PIE 334 is a direct like for like replacement for the superseded Altek 334 loop calibrator, with enhanced accuracy and rugged dependability. Source or read milliamps. Simulate or read the two-wire transmitter. With the 334, performing calibrations on the mA transmitter, recorder, or I/P transducer has never been easier. You'll be able to confirm controller outputs or read the mA signal at any point in the loop. This versatile loop calibrator also boasts an accuracy rating of ±0.025%. A specialised feature of the 334 is a switch for instantly outputting 4 or 20 mA with accuracy to ±0.006 mA.

The PIE 334A comes with a 3 year factory warranty, but based on the evidence to date, this little calibrator could still be capable of doing the job well after you've retired!
