Altek 334A mA Loop Calibrator

This item has now been discontinued. Please see the PIE 434E Loop Calibrator for a functional replacement.

With the Altek 334 loop calibrator, you’ll be able to check 4 to 20 mA loop functions quickly and accurately. You’ll have mA, % of Span, and DC V at your fingertips. 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 ±0.03%. A specialised feature of the Altek 334 is a switch for instantly outputting 4 or 20 mA with accuracy to ±0.006 mA.

Calibrate transmitters, recorders, controllers, alarms, indicators, process data acquisition and computer systems using the 134-2. The Altek 334A comes with a 3 year factory warranty, but based on the lifespan of units out in the market, this little calibrator could still be capable of doing the job well after you've retired!
