"Our job is helping you do your job"
The Meriam M334 is a state of the art, highly reliable, rugged and easy to use milliamp calibrator. It has the functions necessary to perform all the required maintenance and calibration tasks of virtually any 4-20mA loop. It provides source and read milliamp functions along with power and measure; and two wire transmitter simulations. In addition it can measure DC Voltage for troubleshooting power supplies.

Source 0.00 to 24.00 mA (-25.0% to 125.0%)
Read 0.00 to 52.00 mA (-25.0% to 300.0%)
