Multi-Gas Monitors offer a broad range of protection and detection of dangerous and toxic compounds, which is a necessity in the world of confined space entry. BW Technologies and RAE Systems are frontrunners in this field, each with their own range of handheld detection solutions.
Standard gas detection is for H2S, SO2, CO and O2 levels, alerting you to any dangerous peaks of troughs in their atmospheric presence. One of the main advantages of the EntryRAE portable gas sniffer is that it features a Photo Ionization Detector (PID); this allows it to detect a wider range of potentially volatile organic compounds (VOC) that may not be detected by other standard sensors.
There are detectors with an internal pump, such as the QRAE II
and the Gas Alert Max XT II
, which allow easy sampling of remote areas. Each have the four standard detectors, offer hours of battery life and data logging.
The QRAE II is available as a diffusion detector (without the internal pump) while BW Honeywell has the Quattro
and smaller MicroClip
multi-gas detectors as their diffusion offerings.
Each of these detectors will do the job of sampling the atmosphere. For anyone seeking to perform manhole entry or sample remote atmospheres then consider a detector with a built-in pump (although both RAE systems and BW offer manual aspirator pumps for their diffusion detectors, so this is still possible) such as the GasAlertMax XT II
Crucial for any confined space work site, those working on refineries, in mines, sewers or any other enclosed space will all reap the passive protective benefits of these highly portable, reliable multi-gas detectors.
