Single gas monitor - pro series

The ALTAIR Pro Detector uses highly accurate electrochemical sensors to measure concentrations of toxic gas (ammonia, carbon monoxide, chlorine, hydrogen cyanide, hydrogen sulfide, nitrogen dioxide, phosphine and sulfur dioxide) or percent oxygen depending on instrument version. This measurement is clearly displayed on the instrument's LCD. The detector is fast-responding and has clear alarm functions to alert the wearer. The ALTAIR Pro Detector automatically records the last 50 alarm or test events and has active data-logging. To read data or change alarm set points simply connect the unit to an MSA infrared adapter using the built-in IR communication port. http://media.msanet.com/NA/USA/PortableInstruments/ToxicGasandOxygenIndicators/Altair/0800-31.pdf
