M334 4-20Milliampere circuit calibrator surface

Meriam M334 is technologically advanced, highly reliable, structurally robust, and easy to use with a milliampere calibrator. It has the necessary functions to complete all the maintenance and calibration work required for the 4-20mA circuit. It provides source and milliampere reading functions, as well as power supply, measurement, and two-wire transmission simulation functions. In addition, it can measure DC voltage to troubleshoot power supply faults.
This M334 is functionally equivalent to a similar calibrator, but has many additional benefits. These improvements include improved long-term stability, accuracy, reliability, and durability (including significantly extending the battery's lifespan). The comprehensive improvement of MeriamM334 has enabled it to achieve or exceed the expected performance and performance of similar products
While maintaining its well-known and proven reliability, as well as the ease of use of similar calibrators, M334 also surpasses the performance level of many high cost calibrators and meets today's most demanding requirements. This is the new standard!
