Based on the industry standard ALTAIR Single-Gas Detector, but with added features and functionality the ALTAIR Pro toxic gas and oxygen detectors combine reliable detection and LED/audible/flashing/vibrating alarms with clear, backlit LCD displays. Electrochemical sensors measure concentrations of toxic gas (chlorine dioxide, hydrogen cyanide and phosphine) or percent oxygen. Purpose-built for superior dust and water protection, excellent impact resistance and excellent RFI performance.
