The ALTAIR® Pro Single-Gas Detector is designed for reliable detection of Hydrogen Cyanide (HCN) in industrial environments where toxic gas exposure is a critical risk. Based on the industry-standard ALTAIR platform, the Pro version adds enhanced functionality, including a large backlit LCD display and adjustable alarm set points. Equipped with an electrochemical sensor, it provides continuous HCN monitoring with preset low alarm at 4.7 ppm and high alarm at 10 ppm, supported by a robust quad alarm system for clear hazard notification.
