Product Introduction

This instrument is developed and designed according to the national power industry standard DL/ t506-2007 "insulation gas humidity measurement method for sulfur hexafluoride electrical equipment", and adopts the imported high-precision dew point sensor and new digital circuit control technology. It is a high-precision intelligent instrument to measure the trace moisture content in SF6 gas.

This instrument adopts intelligent self-calibration technology, wide measurement range, fast response, high accuracy, good linearity, dynamic display of measurement curve. At the same time, the instrument also has an automatic dryer, which can greatly reduce the measurement time.

Product nickname：intelligent micro water meter, micro water meter, micro quality meter.
