In continuous production for nearly 25 years, the MeriCal digital pressure transmitter calibrator is one of the most successful instruments to ever serve the process industries. Meriam’s NEW M4 Series Handheld Precision Calibrator / Data Logger builds on this reputation with an impressive array of new features, functions and improved accuracy specification.

The M402 can be configured with any two gauge, compound or absolute type sensors. Accuracy is ±0.025% of Reading from 10 to 100% of range and ±0.002% of Full Scale below 10% of range. Accuracy is maintained over operating temperatures from -20º to +50º C (-4º to +122º F). Data Logging is standard on all models

All M4 Series handhelds provide convenient electrical signal measurement and sourcing. Measure ±50V or ±100mA, source 24VDC, sink V, or source precise VDC or mA DC values using the supplied test leads. Accuracy is ±(0.015% of Reading + 0.002 units) over the entire operating temperature range. Source or sink values are easily entered using the Adaptive Interface Wheel and right arrow function key.
