An  IndicatorPlug  is a colorimetric filter breakthrough indicator device.  It indicates a saturation of a carbon filter and, hence, the need for filter change.  The IndicatorPlugs are equipped with a spontaneous and time-lapse indicator assembly (patented).  IndicatorPlugs provide excellent color stability and  minimize false negative results due to overexposure and interference effects.

A FilterLife indicator plug indicates the pre-breakthrough state of the contaminant.  FilterLife  is equipped with a colorimetric indicator assembly and a probe.   The probe channels air flow from inside of a carbon filter to the indicator assembly.  It enables the detection of a target contaminant ahead of its breakthrough to the environment.

IndicatorPlug V3  is a flow contaminant indicator device used for monitoring of hazardous gases and vapors.  Flow contaminant  indicators are equipped with two connectors on two ends.  The connectors are threaded and glued permanently. In all other chemical and physical properties, it behaves the same like filter breakthrough indicators. View Products.

Hazardous substances can be present in forms of products, byproducts, spills, leaks or wastes and can be gases, vapors, solids or liquids. In workplaces of such environments, there is always a chance of encountering some risks of exposure to the substances.  In spite of strict measures, hazardous chemicals can often be overlooked and will only gain attention when someone gets hurt.  Commonly, contaminated air is filtered through cartridges filled with granular activated carbon.  Adchemit offers  filter breakthrough indicator plugs highly specific to the respective contaminants.  Filter breakthrough indicators monitoring the end-of-service-life of the carbon cartridges.
