Kaiser Raman AirHead probe

Providing reliable, quantitative gas-phase measurements in a process environment

The Kaiser Raman AirHead probe has cross-industry appeal for its robust gas-phase headspace monitoring, in situ measurements, and material compatibility. In chemical processes, it successfully addresses common gas / vapour phase process application challenges such as corrosivity, wetness of the sample environment, and low sensitivity of analyzer technology. Food & Beverage companies rely on its ability to accurately measure gas-phase volatile organics during sugar fermentations.

Certified for use in hazardous area environments, the AirHead probe can be inserted directly into processes with temperatures up to 150 degrees Celsius and pressures up to 1,000 psi, and it is available with a variety of mounting options for maximum installation and sampling flexibility.
