Introduction
KDWS-A microcomputer-based SF6 micro-water meter is measuring the humidity level of quality replacement. It is from the kernel to the appearance reflects the advanced technology and advanced design , the product is a senior engineer from the company and university technology jointly developed by and is the most important instrument to replace imported products , the majority of experts and user acceptance.

KDWS-A microcomputer-based micro-water meter using SF6 Vaisala DRYCAP (R) and humidity sensor with high accuracy, repeatability, test speed, drift , etc., is in the low dew point and the need to control the dry point ideal for industrial environments. It has a chemical purge option, which makes the product in the environment of high concentrations of chemicals and cleaning agents in stable measurement can be performed accurately , thus ensuring the accurate measurement of the interval between each check .

KDWS-A microcomputer-based micro-water meter as SF6 gas humidity precision testing special instrument for SF6 switchgear substation humidity and hydrogen gas stations , hydrogen-cooled generator hydrogen humidity precision , rapid detection , is also applicable to the metallurgical, chemical, petrochemical, and other industry-specific gases and humidity testing .
