The QRAE II multi gas detector, available in a diffusion model, is a portable, one – to – four detector for gases such as oxygen, combustibles, hydrogen sulfide or carbon monoxide. It has the best EMI/RFI immunity technology for products in its class which minimises electromagnetic and radio interference.
Its unique and patented SPE O2™ Oxygen sensor have features such as a leak-free design which minimises downtime and also an extended lifetime compared to lead-type electrochemical oxygen sensors which can result in a low cost of ownership.
To ensure multi gas detection is carried out safely this 4 gas detector is water and dust resistant according to IP65 standards. The housing of the instrument is strong and concussion-proof to make sure it is protected, even in the roughest of environments.
The large, graphical display can be flipped 180° with the push of a button, to allow easier viewing from belt or by hand and also has multi-language support. The two-button user interface is simple and easy to operate.
RAE’s multi gas detector has audible, vibration and visible alarms to assist multi gas detection.
The QRAE II has a rechargeable Lithium-ion battery pack which can provide up to 14 hours of continuous operation. There is easy to access to the battery compartment, as well as the pump, sensors and filter. The battery pack is also easy to change.
