SDW-LD2080L portable dew point meter

SDW-LD2080L portable dew point meterProduct Introduction

SDW-LD2080L Precision dew point meterIt is a cold mirror precision humidity measurement device based on the physical definition of dew point, which is an instrument that directly measures dew point. This principle instrument is used as a standard for other humidity/dew point measurement instruments.

The SDW-LD2080L precision dew point meter has the characteristics of high accuracy, good stability and repeatability, and long service life.
