This compact portable device, available in both diffusion and pump models, monitors up to four gases in confined spaces. Designed for hazardous environments, it can measure levels of hydrogen sulfide, carbon monoxide, and combustibles, and checks for adequate oxygen with a state-of-the-art, lead-free oxygen monitor. The QRAE II’s water-resistant, dust-resistant, and shock-resistant case provides durability, and three alarms – light, sound, and vibration – to make sure the user is aware of any danger. The intuitive, two-button interface is easy to use, even when wearing two layers of gloves. Plus, with easy access to the pumps, sensors, filter, and battery, maintenance is streamlined.
