MultiRAE Pro

This industry-leading wireless device monitors both chemical threats and gamma radiation and is the only multi-threat monitor with parts per billion precision. With the ability to wirelessly transmit threat and alarm data in real time to a central command station, the MultiRAE Pro offers improved visibility and awareness.

It also gives you the flexibility to swap out 25 different sensors for a range of threats, including VOCs, toxic gases, combustibles, oxygen levels, as well as gamma radiation detection. The large display and replaceable sensors, pump, and battery make it easy to use and maintain, while five different alarms, including man down, provide the versatility you need to respond appropriately and quickly to incidents.

The MultiRae Pro

MultiRAE Pro

Portable Multi-Threat Detector

The MultiRAE Pro is the industry’s only portable wireless multi-threat monitor. The MultiRAE Pro’s ability to simultaneously detect gamma radiation and toxic industrial chemicals (TICs/TIMs) enables responders to reduce the equipment footprint and achieve greater agility when operating downrange.

The MultiRAE Pro’s optional wireless capability improves safety by providing commanders and safety officers real-time access to instrument readings and alarm status from any location for better situational awareness and faster incident response.

The instrument boasts the largest display and longest battery runtime in its class (with an optional extended battery), as well as an ergonomically contoured case that is rugged, dust-tight and waterproof (IP-65 / IP-67 rating). A compartmentalized design of the MultiRAE Pro makes the replacement of its sensors, pump, and plug-and-play battery simple, even in the field, and the AutoRAE 2 Automatic Test and Calibration System ensures bump testing and calibration of up to 10 instruments is as easy as a press of a button.
