Portable multi gas detector

A portable multi gas detector can detect simultaneously up to 6 gases depending on its configuration. The most commonly used device is the 4 gas monitor (combustible gas, O2, C0 and H2S). This configuration is primarily used in water treatment, in the steel industry, for construction and public works, or for confined space entry.

Portable multi gas detector, 4 gas monitor and area gas monitor: gas detection equipment for workers safety

  • The multi gas detectors

    A portable multi gas detector is designed for one goal: to guarantee health & safety at work by gathering information about the quality of the work environment. Thus, a multi gas detector can monitor from 1 to 6 gases simultaneously depending the unit. Compact and lightweight, multi gas meters are more expensive than single-gas detection equipment but feature enhanced functions such as data recording (gas concentration, alarm events), computation of average values & exposure limits, or events traceability.

    4 gas monitor

    The 4 gas monitor is the prime portable multi gas detector and the most commonly used in the industry (water and waste treatment, public works, steel industry, confined space entry …). It can simultaneously detect combustible gases (natural gas, LPG, hydrocarbons, alcohols and solvents), hydrogen sulfide (H2S), carbon monoxide (CO) and oxygen (O2) deficiency.

    Multi gas detector

    For other less mainstream configurations, portable multi gas detectors feature a wide range of additional gas sensors including plenty of toxic gases (ammonia, chlorine, chlorine dioxide, hydrogen chloride, hydrogen cyanide, sulfur dioxide, nitrogen dioxide, nitric oxide, phosphine…), volatile organic compounds (VOC) and carbon dioxide.

  • Area gas monitor

    Larger than a classic portable multi gas detector, this device is not a personal protective equipment but is known as an area protective unit. An area gas monitor is designed to ensure accurate gas detection on a defined zone. Workers can thus easily and safely evolve on a canvassed secured field, and be alerted as soon as a dangerous gas is detected. (see the  The LENS wireless technology).

    With a large autonomy (up to 168 hours) and easily carried, area gas monitors can now also communicate wirelessly with other units to enlarge the monitored area. These safety units are able to detect the classic gas range of a portable multi gas detector (combustible gases, O2, CO, H2S). For more specific usage and requests, a wide range of gas sensors and configurations remains available.

  • Our all included maintenance program

    Almost any single-gas and portable multi gas detector sold by GazDetect is available with our 2-year All Included Maintenance program (in selected locations). This service was created to forecast the calibrations and the periodical maintenance of your gas detection equipment for two years from its purchase date (about 100 euros for a classic 4-gas monitor).

    At the end of these two years, the All Included Maintenance service can be renewed for two more years and so on... At GazDetect we designed this program to help you manage your devices and help you maximize your safety level.
