Multiple gas threats. One easy-to-use transportable area detector.
A wireless area monitor you set down around a scene. It detects toxic and combustible gases, volatile organic chemicals, and, with the optional RAEMet sensor, the meteorological factors that affect the speed and direction of the gas. Crews on scene get local audible and visual alarms; command gets a real-time view of the readings from a safe location through Honeywell's remote monitoring software.
Fence line, maintenance turnaround or emergency response: units go down around the hazard, alarm locally, and send real-time readings back so you can determine the location and severity of a threat without standing in it.
Position units at the fence line, around a turnaround or at the edge of an incident. Turn it on and go: each one monitors toxic and combustible gas and VOCs where it stands, and GPS is standard equipment in every unit.
A multi-tone 108 dB buzzer @ 3.3 ft / 1 m and a bright 360 degree LED warn anyone near the unit, with on-screen indication of the alarm condition.
With the optional RAEMet sensor on top, the unit also measures wind speed, wind direction, temperature and humidity, so the plume's direction and speed are part of the picture.
The built-in Mesh radio lets one AreaRAE Plus act as a gateway for up to 8 remote instruments, such as MultiRAE or ToxiRAE Pro monitors up to 330 feet (100 meters) away.
Readings go to Honeywell's remote monitoring software in real time. The map-based display is accessible from any computer with an internet connection, or from a laptop as a turnkey host, and enables coordination and data sharing in joint operations.
A long-range primary radio (license-free ISM 900 MHz or 2.4 GHz, or IEEE 802.11 b/g Wi-Fi), a short-range Mesh secondary radio, and Bluetooth Low Energy as standard. Radio fit varies by model configuration, and Wi-Fi is optional; ask us about the radios on the unit you need.
Bar lengths are indicative only. Receiving > 80%. Additional equipment and/or software licenses may be required to enable remote wireless monitoring and alarm transmission.
Gas readings tell you what is there. The optional RAEMet sensor sits at the top of the AreaRAE Plus and adds where it is heading: wind speed, wind direction, temperature and humidity, from the same unit, on the same power.
A built-in electronic compass and high sensitivity give RAEMet the wind speed, wind direction, temperature and relative humidity at each unit.
The readings are modeled in Honeywell's real-time monitoring software, which integrates the ALOHA® hazard modeling program jointly developed by the US EPA and NOAA.
Use it to determine where to evacuate, what roads to close and how to prioritize actions. At a fence line, it shows the direction and speed of the plume.
Up to six 4R+ sensors for toxic and combustible gas, plus a 7R+ photoionization detector for VOCs in parts per million with built-in compensation for temperature and humidity. Switch sensors out whenever your needs change.

Need gamma? The AreaRAE Plus is a gas and meteorological monitor without a gamma sensor; its sibling, the AreaRAE Pro, offers an optional one.
See AreaRAE ProOne transportable unit with its own pump, power and alarms: built for short and long-term deployments without a fixed installation.

108-decibel alarm with wraparound LEDs, plus a wireless connectivity alarm and a diagnostic alarm and display message for low battery.
Three solid-state relays (dry contact, 24VDC and 250mA max) switch on gas alarm conditions or a pump failure, for connection to external strobes, horns or other triggers.
Rechargeable 7.2 V / 10 Ah Li-ion battery pack with built-in charger, ~20 hours with wireless connectivity on the Li-ion pack at room temperature (20°C), and an Alkaline Battery Adapter option.
A large 240 x 320 pixel backlit LCD and three big operation keys that are easy to use with industrial gloves. The interface is available in 9 languages.
Easy USB connection to ProRAE Studio II configuration software, no special cable required, and device management with Honeywell Sotera™.
IP 65, MIL-STD-810G and 461F performance tests, and an operating range of -20 °C to +50 °C. US / Canada: Class 1, Division 2 Groups A, B, C, D.
Protect your community at a fence line, your employees during a turnaround, or your fire and hazmat team during emergency response.

Position units at the fence line, then monitor real-time readings from up to two miles away and use RAEMet to determine the direction and speed of the plume.
