Tech for gas detection

By on

With over 300 detectable gases in industrial environments, which can potentially be explosive, toxic or detrimental to health — along with oxygen depletion risk — gas detection is a critical activity performed every day across many applications worldwide.

Everyday industries such as construction, remediation, mining, manufacturing, petrochemical, utility service maintenance and the emergency services rely on this life-saving technology to monitor gas hazards and keep the workforce and the wider public safe.

In the last year alone, huge advances have been made in the technology which enables quick and accurate gas detection and analysis, in terms of performance, functionality and battery life. Here we take a look at some of the best new technology currently on offer from the world’s leading manufacturers.

Wearable gas detection

A standard four-gas monitor is required in a zoned environment but the draw back has always been battery life as traditional instruments usually need recharging after eight hours.

However, the latest personal instruments, such as the BW Clip4 and MGC Simple, provide continuous two- year battery life with no charging and no maintenance required. Simply turn them on and in two years’ time replace the unit. This offers a huge advantage as fleet numbers can potentially be halved with workers able to use the same monitors from the previous shift with complete confidence.

Gas detection plus communication

These days we are used to seeing new technologies merging together into something new. For example, your mobile phone is now a smart phone, a messaging device, a camera, a pocket computer and more. The same product development also applies to gas detection technology and the latest in communication, personal GPS location and gas monitoring have come together in the ground-breaking new G7.

A modular series, G7 offers up to four-gas detection alongside two-way messaging and speakerphone, man down alarms, motion detection and GPS tracking, all transmitted back to a central base and accessible worldwide, 24 hours a day.

If an alarm activates, the issue can be accurately diagnosed and the exact location pinpointed for instant response. Live readings from the device can help identify the incident circumstances, so rescue teams are forewarned of the issues they will
be encountering.

Gas leak detection

In terms of handheld detection, both the GasCheck 3000is and 5000is are designed specifically for locating flammable gas leaks and can detect and measure almost any known gas or gas mixture.

Calibrated against helium, they are particularly sensitive to ammonia, argon, butane, hydrogen, SF6 and refrigerants and are ideal for use in zone zero areas. The 3000is model measures in cc/sec and g/yr, while the 5000is also has a ppm scale and datalogging capabilities.


The latest portable monitor in this category is the highly-customizable MultiRAE benzene six-gas, the only monitor that includes up to six-gas detection, real-time wireless capability and specific benzene measurement. The MultiRAE Benzene combines the ability to make snapshot benzene-specific measurements while supporting up to 20 intelligent, interchangeable sensor options.

Its unique features make it the ideal instrument for industrial applications from refinery downstream monitoring and confined space entry pre-screening to personal protection and leak detection.

Benzene fixed

Finally, for fixed, continuous, real-time benzene monitoring, Titan is the first truly selective, wall-mounted monitor designed specifically to detect benzene in petrochemical environments. It provides minute-by-minute sampling for continuous real-time data, even at extreme temperatures.

With all of this latest technology now available, those working in hazardous gas areas can feel confident their gas detection equipment will monitor more effectively, offer extended battery life and provide better protection than ever.

Financial worries can have a negative impact on both an employee’s general wellbeing and work performance, so it makes sense for employers to educate staff about the financial benefits available to them and how to manage their finances. Online platforms are one of the most effective ways of providing this advice.
