Filter Breakthrough Indicators Overview

Chemteq breakthrough indicators are colorimetric filter change indicators that indicate the saturation of filters in real-time. They are reliable and cost effect means for protection from exposure to toxic gases and vapors. Indicators change color when filters are saturated with target gases or vapors. It alert the user to replace the exhausted carbon adsorber or filter. Extended shelf-life range between 1 to 2 years. Plus service life range between 1 to 2 years. The unique design of the indicator prevents any color change due to exposure to contaminants in the surrounding environment. It changes color only when carbon absorber or filter is saturated. Breakthrough indicators are available for wide variety of chemicals.

Chemteq filter change indicators include:

Breakthrough indicators for low-flow filters BTI LFF suitable for hplc waste container filters.

Filter change indicators BTI (inlet 0.75” NPT), BTI 2 (inlet 1.5” NPT) and BTI 3 (2.5” NPT).

Filter change indicators Inline (BTI Inline) and filter change indicators with auxiliary filter trap (BTI AFT).
