Gas Detectors Altair PRO Single Gas Detector 1-2 Gases
Based on the industry standard ALTAIR Single Gas Detector, but with additional features and functionality. ALTAIR Pro Single Gas Detectors for oxygen and toxic gases combine reliable detection and audible, intermittent, vibrating, LED alarms with clear backlit LCD displays. Electrochemical sensors measure concentrations of toxic gases or percent for oxygen (O2, ClO2, HCN, PH3). Built specifically for dust and water protection, excellent impact resistance and excellent RFI performance. ALTAIR Pro combine reliable detection and LED / audible / flashing / vibrating alarms with clear, backlit LCD displays.
The Altair Pro's unique design makes it a functional, durable, and reliable single-gas detector. Therefore, it is easy to use and easy to maintain in operating condition. Part Based on the industry standard ALTAIR single gas detector, but with added features and functionality, toxic gas and oxygen detectors. Electrochemical sensors measure toxic gas concentrations (chlorine dioxide, hydrogen cyanide, and phosphine) or percentage of oxygen. Built specifically for superior dust and water protection, excellent impact resistance, and excellent RFI performance.



The Altair Pro detector is a portable single-gas instrument, which uses electrochemical sensors and a replaceable battery that make it operate for long periods of time. The Altair Pro single gas detector offers superior protection against the ingress of water and dust, giving it a great capacity to work in the harshest industrial environments. It includes an excellent triple alarm system (visual, audible and vibrating). It is also designed and manufactured to the highest MSA standards to guarantee its use and handling in industrial environments. Its maintenance is very simple. It is available to measure the following gases: CO, H2S, O2, Cl2, CLO2, SO2, NO2, NH3, PH3, HCN.
