MultiRAE Plus & Wing Tank Entry Kit

MultiRAE Plus
5-Gas Monitor with VOC Detection

The MultiRAE Plus combines a PID (Photoionization Detector) with the standard four gases of a confined space monitor (O2, LEL, and two toxic gas sensors) in one compact monitor with sampling pump. Like the LeathermanTM tool, the MultiRAE Plus gets the job done in more circumstances than any other gas detector. With more than 10,000 units in the field today, its versatility makes it the gas meter of choice for some of the highest profile HazMat/WMD teams in the United States. The MultiRAE Plus is quickly and easily changed from a sophisticated technician instrument to a simple text-only monitor. The same monitor can be used as a personal monitor, a hand-held sniffer, or as a continuous operational area monitor.


Communication kits and repeaters providing wireless capability for portable VOC gas monitors

The MultiRAE Plus detector can be made wireless with the use of RAELink2. This allows real-time monitoring information from the detector to be integrated into an existing AreaRAE system. A wireless, RF (radio frequency) modem allows detectors equipped with Firmware version 1.20 or higher to communicate and transmit readings and other information on a real-time basis with a remotely located AreaRAE base controller up to two miles away.


The RAELink2 Wireless Modem is a key building block of the AreaRAE Wireless Platform. It is built into the AreaRAE monitor and is used in a stand-alone configuration with the ProRAE Remote Base Station, RAE Systems portable monitors and a wide variety of third-party products.

RAELink2 allows real-time data transmission between the monitors and the base station, which can be located up to two miles away. Each ProRAE Remote Base Station can communicate with and display data from up to 32 remote monitors.

AreaRAE is the industry’s leading platform for rapidly deployable wireless networks used for detecting and monitoring hazardous substances. Already deployed and operated by hundreds of leading public safety agencies and corporations, AreaRAE represents the industry’s standard of choice.

The AreaRAE Wireless Platform integrates information from a wide variety of sensors and monitors, including the following:
  RAE Systems AreaRAE and AreaRAE Gamma Monitors
  RAE Systems wireless portable monitors: MiniRAE 2000, ppbRAE Plus, and MultiRAE Plus
  Coastal Environmental Systems WEATHERPAK® portable weather station
  A wide variety of third-party products for chemical weapons detection and other applications



Automated Bump and Calibration Station
GammaRAE II Responder

GammaRAE II is the first personal radiation detector (PRD) to provide rapid detection of gamma (γ) ray sources even in potentially flammable environments. Certified intrinsically safe and water-immersible for chemical decontamination purposes, the GammaRAE II can be safely used in more environments than any other PRD.

The sensitive Cesium Iodide (CsI) scintillator of the GammaRAE II provides a fast, two-second response to radiological threats. GammaRAE II alerts the wearer with a loud 85+ dB audible alarm, big, bright flashing LEDs, and a vibration alarm. For stealth operations, law enforcement personnel can disable each alarm individually.

The GammaRAE II accumulates approximate dosage. Dosage data stored can be cumulative or cleared and reset for each use period. IS Certification permits operation in potentially flammable/explosive environments.

GammaRAE II: Personal Radiation Detector

The GammaRAE II personal radiation detector (PRD) is available as a detector only or as a combination detector and dosimeter. Certified intrinsically safe and water-immersible for chemical decontamination purposes, the GammaRAE II can be safely used in more environments than any other PRD. It is currently used by many HazMat, fire, law enforcement and security teams worldwide.

The MultiRAE Plus Wingtank Entry Kit is a unique solution customized to improve the safety of any wingtank entry program. RAE Systems has helped a number of major airlines, air forces and aircraft manufacturers put together a simple program that utilizes the MultiRAE Plus’s PID (Photoionization Detector) instead of traditional wheatstone bridge LEL (Lower Explosive Limit) sensors for measuring jet fuel vapors. Simply put:

Wheatstone bridge sensors are designed to measure methane, not hydrocarbons. Jet fuel is a mixture of hydrocarbons, and PIDs are the best compact hydrocarbon detectors.

PIDs are a superior sensor for Lower Explosive Limit (LEL) alarms in the jet fuel environment because their sensitivity makes them less prone to false alarms. PIDs provide users with greater confidence in their meter readings and thus greater confidence in their safety when entering a potentially hazardous environment.

The MultiRAE Plus Wingtank Entry Kit is customized specifically for entering aircraft wingtanks that previously contained jet fuel. The monitor's alarms, gas measurement scales, and calibration gases are all specially tailored for use in environments containing jet fuel vapors. In addition to a PID, the MultiRAE Plus used in our Wingtank Entry Kit also includes an Oxygen sensor and a traditional LEL sensor that provides a backup reading for the PID. While the MultiRAE Plus has an additional 2 toxic gas sensor sockets that may be filled with CO, H2S, or any two of our 10 toxic gas sensors, these two toxic sockets are not filled in the MultiRAE Plus Wingtank Entry Kit as they are typically not required in this particular environment.

The MultiRAE Plus is truly the next generation of gas detection, and has proven to be uniquely suited to the aircraft jet fuel environment:
  PID sensor provides reliable and consistent readings
  Strong pump allows sampling from wing access ports prior to entry
  Small size lets you carry the kit into large center tanks or take it into tight, baffled areas that are difficult to reach with a remote sample hose
  Durable rubber boot protects the MultiRAE Plus from abuse and keeps it from sliding off of smooth wing surfaces
