The Altek 334A Milliamp Loop Calibrator is designed for precise verification, calibration, and measurement of 4–20 mA DC current loops. It sources and reads from 0.00 to 24.00 mA, simulates two-wire transmitters, and powers transmitters up to 27V DC. With its speed-sensitive digital potentiometer, it can set values to 0.01 mA resolution. It features an accuracy of ±0.006 mA and supports fixed points at 4.00, 20.00, and a customizable third point.
Compact and lightweight, the Altek 334A allows simulation of process inputs to test loop response and control settings. It measures controller outputs, verifies milliamp signals at any point in the loop, and operates on three 9V batteries, providing over 20 hours of sourcing or 150 hours of measurement.
Testwall can supply the used Altek 334A, fully tested. With expert support and global delivery, Testwall ensures high-performance instrumentation with unmatched reliability and service quality. Please contact us directly if you need calibration or repair of the Altek 334A.
