The Honeywell SPM FLEX is a toxic gas optical analysis system with high performance, rapid response time, insensitive to interference and using the patented Chemcassette technology. It is particularly suitable for monitoring very dangerous gases such as nitric acid (HNO3), sulfuric acid (H2SO4) or isocyanates (TDI, HDI, MDI).
This advanced technology combines chemically-impregnated paper color change with a very powerful optical analysis system. Measurements are targeted, precise and rapid at extremely low concentration levels, with ppb resolution (part per billion). Detailed description
The Chemcassette technology
Gases sampled by a sampling pump are sent to a strip of chemically impregnated paper. In reaction with the target gas, the paper strip will change color to be analyzed by a very powerful optical system. It is a very precise method for analyzing the most sensitive toxic gases, such as hydrides, mineral acids, oxidants or amines.
