Nanotechnology-based, Ultrafast Hydrogen Sulfide Gas Sensor

(Nanowerk News) Detector Electronics Corporation (Det-Tronics) has announced an NTMOS hydrogen sulfide (H2S) gas sensor that detects low H2S gas concentrations in five seconds or less while tolerating harsh environments that experience extreme temperature and/or humidity conditions ( Det-Tronics is part of UTC Fire & Security, a unit of United Technologies Corp.
Third-party tested to ISA-92.0.01, the NTMOS H2S gas sensor detects hydrogen sulfide in conditions that harm electrochemical and standard MOS sensors. The sensor is packaged in a rugged housing, protected by a sintered stainless steel flame arrestor, and can be installed in Class I, Division 1 locations. The NTMOS gas sensor can be installed as a stand-alone sensor or combined with a display for local indication.
"We look forward to partnering with customers to reduce the occurrences of hydrogensulfide injuries and deaths," said Cliff Anderson, Marketing Director at Det-Tronics. “Our new detector alerts people to the presence of hydrogen sulfide in less than half the time of other detectors. And the onboard humidity and temperature sensors ensure accurate and repeatable readings."
