Search for Infrared Sensor for Water Vapor Test

Vaporstat 9002 any use?

Thank you very much for your kind assistance.

You could do a Globalspec search. Some manufacturers that might help are Inotek, Rosemount, Ametek, Bacharach Instrument.

Thank you very much

The good news is that a number of simple silicon sensors available from many sources will measure absoption in the near IR band commonly used in water vapor analysis. The bad news is that water analysis by absorption is normally considered a secondary standard and requires frequent calibration against primary standards. For this reason, we always recommend the use of primary standards whenever possible. For water concentratrion between 1-5000 ppmv a dew point analyzer is a low cost primary measurement that can be used in many applications. The newer laser ring down equipment is more expensive and complicated, but also is a primary measurement tool.

Thanks a lot

As far as I know ring down lasers are not a primary standard for moisture mesurement, only a chilled mirror is considered a primary standard.

Thanks a lot!

I have sent you a email, please check it out. thank you.

Dear Merken,
