GrayWolf DirectSense TVOC Measures IAQ Parameters

GrayWolf Sensing Solutions, Trumbull, Conn., has introduced the DirectSense TVOC monitoring kit
to measure total volatile organic compounds (TVOCs) and other indoor air quality (IAQ)

The kit includes sensors to measure TVOC concentrations in parts per billion or parts per
million, relative humidity and temperature. Up to three electrochemical gas sensors may be mixed or
matched to measure a choice of gases such as ozone, ammonia, chlorine, carbon monoxide, hydrogen
sulfide and oxygen, among others. Other probes may be added to monitor carbon dioxide, particle
counts, differential pressure and other parameters. On-board sensor tips, government and industry
guidelines, and a report template also are included, as well as desktop PC software.
