Overview
KPA-300 is a portable moisture and vacuum meter that measures moisture concentration, dew point, vacuum, flow and external pressure of gases.
With a high-precision moisture sensor it measures moisture from 10 to 23,000 ppm and dew point from -60 to +20℃, along with vacuum from 0 to 760 Torr and gas flow from 0 to 5000 sccm.
It has a 5-inch TFT color touch screen and quick-coupling connections, and is used for moisture measurement of insulating gas in GIS and GIT and for preventive diagnosis of power equipment.
