Add to wishlist

The measuring principle of the dewpoint mirror is a highly accurate and reliable method for measuring the absolute humidity of air or other gases.

The presented model belongs to the third generation of dewpoint mirror measuring systems, which now feature extended measuring ranges and meet modern requirements with respect to operation and data processing.

The Dewpoint Mirror Measuring System TS-2 is designed for the use as stand-alone unit or it can be integrated into the widest range of equipment.

Due to its high precision and stability, it can be used for:

  Calibration of humidity sensors

  Humidity determination in meteorological institutes

  Control or alarm monitoring applications, for example in fabrication facilities for water sensitive materials

  As part of bypass humidity-control units and for the determination of plant evaporation in photosynthetic gas exchange systems
