Micro Water measurement instrument - ZS142

ZS142 Micro Water measurement instrument

Overview
ZS142 Precise dew point measure equipment meets the national standards of GB 5882.2–86: The Determination of Osmosis in the Air (Dew point method).
Hubei Zhongshi Co., Ltd. is professional in dew point measurement and gas detection, has many years of practical operation experience. The newly produced ZS142 is more humanizing, site operation and instrument saving were all in consideration.
The equipment adopts Finland VAISALA Sensor which used several latest research and patented technology of dew point measurement, is suitable for micro moisture detection in dry gas. The gas measured include: H2, SF6, N2, O2, Ar2, CO2, compressed air and other gas. LCD display, and direct measurement of dew point, PPM and the absolute humidity; sensor protect function; anti-sensor condensation and oil and gas pollution. Stable test accuracy, automatic self-check function, patented design of absolutely airtight gas barrel has built-in desiccant without interfering with the measurement, which greatly increases the service life of the sensor. Short response time; imported sealed type connector. When not working, the internal of the instrument is totally sealed. Besides, various stainless steel connectors fit to SF6 switch are optional.
