QRAE II (Pump/Diffusion)
The QRAE II is a compact, one- to four-sensor multigas detector for oxygen, combustibles, hydrogen sulfide or carbon monoxide. Key features include easy-to-change battery pack, a water-resistant case and a new O2 sensor. The pump model incorporates an internal sampling pump, while the diffusion model relies on ambient air exchange.
