A pumped multi-gas monitor you build around the job from 25 intelligent interchangeable sensor options, including PID for VOCs, NDIR for combustibles and CO2, and electrochemical sensors for toxic gases and oxygen. Six readings require the CO + H2S combination sensor, which reads both CO and H2S from a single sensor position. Honeywell positions it for industrial hygiene, personal protection, leak detection and HazMat response.
The MultiRAE family can display readings from one to six sensors, depending on the configuration. Below are the 25 sensor options, grouped into five families, with range and resolution. Sensors marked “Sold separately” also have their own product page as replacement parts.
A two-gas combination sensor is required for a 6-gas configuration. That sensor is the carbon monoxide (CO) + hydrogen sulfide (H2S) combo. That one sensor reads both CO and H2S from a single sensor position.
The unit pictured above reads oxygen, LEL, CO, H2S and VOC.
Photoionization detection for volatile organic compounds. The PID sensor requires a pumped configuration; this model has a built-in pump.

Honeywell calls the MultiRAE highly versatile and customizable. The body that carries those sensors is rated dust-tight and protected against water jets, and the display turns itself the right way up.

Dust-tight and waterproof against hosing jets coming from all directions.
Performance tests also include LEL CSA C22.2 No. 152 and ISA-12.13.01.
Operating temperature, at 0% to 95% relative humidity (non-condensing).
Backlit, with an automatic screen “flip” feature. Readout includes STEL, TWA, peak and minimum values, and the PID measurement gas and correction factor.

Unmistakable five-way local and remote wireless notification of alarm conditions, including Man Down Alarm. Alarm mode is your choice: Auto Reset or Latched.
95 dB @ 30 cm.
Vibration alert.Disabled whenever the alkaline adapter is used.
Flashing bright red LEDs.
On-screen indication of alarm conditions.
Wireless remote alarm notification, on units ordered with the optional wireless capability.

The MultiRAE has a 3D gravity sensor that can track the slightest motion of the instrument in any direction. Man Down Alarm comes with a pre-alarm and real-time remote wireless notification. These are the default settings:
Off by default.

By default.
With real-time remote wireless notification.
Note: when a MultiRAE is connected to an AutoRAE 2, truck mount, or desktop cradle, the Man Down alarm feature is disabled.
Wireless and non-wireless configurations are available. With the optional built-in RF modem, commanders and safety officers get real-time access to instrument readings and alarm status from any location, for better situational awareness and faster incident response.
Typical ranges. Additional equipment and/or software licenses may be required to enable remote wireless monitoring and alarm transmission.

The MultiRAE battery packs are plug-and-play and can be replaced on the go without tools. Three power options, and the consumables we stock to keep it running.
Runtimes are for non-wireless monitors. The alkaline adapter takes four AA alkaline batteries (use only Duracell MN1500); alkaline batteries cannot be recharged, and the vibration alarm is disabled whenever the alkaline adapter is used.
Standard duration rechargeable Li-ion battery. ~12-hr. runtime, < 6-hr. recharge time.
View product Battery · M01-3054-000One is supplied with each instrument; this is a spare or replacement. Holds 4 x AA batteries, ~6-hr. runtime.
View product Consumable · pumped unitsIf a filter is dirty or clogged, unscrew it from the black gas inlet adapter, discard it and fit a new one.
View productFully automatic bump testing and calibration with AutoRAE 2, or manual calibration. Policy enforcement can require calibration and/or bump tests at set intervals (disabled by default).
The MultiRAE must be calibrated if it does not pass a bump test, or at least once every 180 days, depending on use and sensor exposure to poisons and contaminants.
Continuous datalogging at 1-minute intervals, 24/7, with user-configurable intervals from 1 to 3,600 seconds. Data are retained in non-volatile memory.
Only authorized personnel should replace the pump, and any attempt to change it yourself voids the warranty. Contact Honeywell or your Honeywell Distribution Center, or ask our Repair Depot how we can help.
