Chilled Mirror Dew Point Hygrometer

       Multifunctional, portable dew point humidity meter , especially designed for field use. Typically apply to dew point measurement of SF6gas.


* Based on the principle of chilled mirror. 
* Accurate measurement is guaranteed. 
* The system is stable, No need to repeatedly calibrated. 
* A built in electronic sample gas flow monitor. 
* Use RS-232 data output to connect with PC.


DP29-40 is specifically designed for air dew point measurement. It is applicable to standard reference for electronic component durability , dew point control for firing furnaces, dew point control for fuel cell test system, etc.
DP29-SF6 is specially for the measurement of Sulfur Hexafluoride (SF6). 
DP29-60 is a standard type. It applies to standard reference for laboratory calibration, moisture control for ceramic firing furnaces, humidity control for thermo-hygrostat chamber.
