The Meriam M334 loop calibrator is a state of the art, highly reliable, rugged and easy to use milliamp loop calibrator. The M334 performs the functions necessary to perform all the required maintenance and calibration tasks of process loops. It provides source and measurement of  milliamps. It will also power and measure a two wire transmitter simulations. Of course it will also measure DC Voltage for troubleshooting loop power supplies.

Let's face facts, the loop calibrator market is crowded. The Meriam M334 is equal to similar calibrators with many added features. These features include better long term stability, accuracy, reliability and ruggedness. A significantly improved battery life is also designed into the unit. The combined improvements allow the Meriam M-334 to meet or exceed all of the expected performance and functions of similar products.
