Hydrogen sulfide waterproof (WP) Breakthrough Indicator is qualitative (yes/no) colorimetric indicator of the end-of-service life of ductless hood filters. It is designed to provide real-time indication of the saturation and breakthrough of hydrogen sulfide. It operates at temperatures 4oC to 32oC (39oF to 89.6oF) and humidities 5% RH to 85%RH. The indicator is 0.12” thick and 1.25” diameter. The unique design of the indicator prevents any color change due to exposure to contaminants in the surrounding environment and changes color only when filter is saturated. The indicator has extended service life of 2 years plus 2 years shelf life. Water has no effect on the indicator.
