Continued development and refinement of advanced low-power LED photometric infrared technology for LEL detection of hydrocarbon gases has made gas detection safer, simpler and more reliable than ever before.
In recent years, new high-performance/low-maintenance portable multigas detectors featuring infrared technology have been utilised in a variety of confined space site applications to keep workers safe. Even in the most extreme conditions, they have been depended upon to immediately warn workers of the presence of deadly gases such as hydrogen sulphide (H2S), carbon monoxide (CO) and combustible gases (Lower Explosive Limit – LEL) as well as a lack of oxygen in the air.
Tested technology you can trust
Utilisation of infrared technology in gas detection is not something new. It has proven to be a reliable method of detecting multiple gases in fixed gas detection applications for many years. Just like the advancement of technology in the phone industry has allowed phones to become smaller and portable with better performance, advancement of infrared technology in the gas detection industry has allowed multigas detectors to become lightweight and wearable with superior performance. Multigas detectors with low-power LED photometric infrared technology are now able to provide a constant personal warning system with no down time.
Advancements have lengthened run time from months to years
When first introduced five years ago, portable multigas detectors with infrared LEL sensor technology were able to operate continuously for 24 hours a day, for two months or longer, without workers having to recharge the battery or perform continual calibrations. Advancements in LED photometric infrared technology have led to the development of multigas detectors today that are warranted to run for as long as two and three years continuously with no charging and no calibration necessary. Multigas detectors can now perform, much like single gas detectors, for years at a time with very little or no maintenance.
Two multigas detectors on the market today feature this advanced sensor technology, the two-year run time Multi Gas Clip Simple and the three-year run time Multi Gas Clip Simple Plus by Gas Clip Technologies. Just turn them on, clip them on, and these instruments will detect the presence of gas for years without having to be recharged. The time consuming and resource consuming task of performing continual calibrations due to combustible gas sensor poisoning or desensitisation is not necessary either. How do these new portable multigas detectors perform this well for this long even under the harshest of conditions?
It’s not the battery type, it’s the sensing technology
The secret is in the technology. Low-power LED photometric infrared LEL sensor technology for portable gas detection has an extremely low drain on the detector’s battery, enabling it to last and last. Think about the comparison of an old energy-consuming incandescent light bulb with a new energy-efficient light-emitting diode (LED) light bulb. Like the LED light bulb, an LED photometric infrared LEL sensor doesn’t have to continuously heat up to perform its function. This conservation of energy allows the battery to last for years, keeping workers safe around the clock and eliminating the risk of a detector powering down in the middle of a job.
