DP29 is a 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.
DP29-70 is a high-end type. It is suitable for moisture control of drying
process, production process of lithium ion battery , measurement of
gas with low dew point.
