External pressure module MF680


Process instrument calibrator designed for field technicians and industrial maintenance professionals. Its multifunctional capacity translates into great versatility when calibrating different instruments.

An ideal instrument for field adjustments or calibrations of process instruments

The MF680 multifunction process calibrator manufactured by Gometrics is an instrument that combines technology, robustness and ease of use. Ideal for field adjustments or calibrations of a wide variety of process instruments, an ideal compromise between performance, dimensions, ease of use and cost.

The MF680 calibrator is a microprocessor-based digital pressure gauge. The instrument is equipped internally with a strain gauge sensor in stainless steel for ranges above 1 bar.

The new MF680 can also measure or generate current simultaneously. The indication of both variables on the display saves time, while the possibility to work in percentage values for input and output signals reduces the risk of error in the calibration of pressure transmitters.
