Chemteq Filter Breakthrough Indicators

Chemteq Filter Breakthrough Indicators are reliable and cost effect means for protection from exposure to toxic chemicals. Easy to use. Simply attach the Breakthrough Indicator to the outlet of filter. Available in different sizes.

Provide real-time monitoring of filter status. It operates at temperatures 4oC to 32oC (39oF to 89.6oF) and humidities 5% RH to 85%RH. It is 0.12” thick and 0.75” diameter.

Because of the unique design, breakthrough indicators don’t color change due to exposure to contaminants form the surrounding environment. It changes color only when filter is saturated.

Depend on application, the breakthrough indicators have service life between one and two year plus shelf life between one and two year.

Available for wide range of chemical hazards.

Custom products and OEM. Because of our on-site equipment, chemists, and engineering team, we can assist clients in research and development projects.
