HS-6650 SF6 gas dew point meter

The photoelectric auto-balanced cold mirror dew point meter is an instrument dedicated to detecting the humidity of a gas. The use of semiconductor refrigeration elements to achieve a "cold mirror" surface to create a low temperature zone, so that the sample gas sweeping across the surface of the mirror is cooled, and a saturated vapor pressure is formed, condensation or frost on the surface of the cold mirror.

Main feature

1, for SF6, CO2, N2, H2 and other gas detection.

2. Simplify the operation procedure and ensure the maneuverability of the instrument as much as possible while ensuring the basic functions and the test accuracy is not reduced. For example, cancel the unusual keys such as forced heating and forced cooling, replace the straight-through chuck with a quick plug, simplify the pneumatic connection procedure, and facilitate learning and mastering.

3. This instrument is a new design product that introduces advanced digital processing technology. In addition to simultaneous detection of sample gas temperature and dew point temperature, it can also automatically convert relative humidity RH%, volume to humidity ratio PPm/v, absolute humidity. Parameters such as g/m3 are displayed on the LCD.

4. This product can be tested with pressure. After the pressure sensor is installed, automatic pressure compensation can be performed to meet the test requirements under different air pressure conditions.
