If you work with combustible gas detection long enough, you will eventually run into a detector that looks perfectly healthy, powers up normally, passes a visual inspection, and yet completely fails to respond to gas. …
If you’ve worked with infrared gas detectors long enough, you’ve almost certainly been called out to investigate a “gas leak” that turned out to be nothing more than water. Condensation is one of the most …
No, an NDIR sensor cannot detect hydrogen, and it never will. This isn’t a limitation of current technology or something manufacturers will eventually engineer around. It’s a hard boundary set by molecular physics. I’ve spent …
If you’ve ever pulled a portable multi-gas detector off the charging dock only to find it dead by the end of a 12-hour shift, there’s a good chance the culprit isn’t your battery. It’s your …
If your gas detector’s oxygen sensor fails when you need it most, the consequences can be fatal. Oxygen-deficient atmospheres are among the leading causes of confined space deaths, and in nearly every incident report I’ve …
The oxygen sensor is arguably the most important in your gas detector. It’s the one standing between you and an atmosphere that can render you unconscious in seconds without any warning smell, taste, or color. …
Choosing the wrong combustible gas sensor can leave your team blind to a hazard or drown them in false alarms. After years of specifying, commissioning, and troubleshooting gas detection systems in industrial facilities, I can …
If you strip a standard 4-gas monitor down to its most essential component, it isn’t the combustible gas sensor or the H₂S sensor most people worry about. It’s the oxygen sensor in gas detectors that …
If you do any kind of gas detection on the job, you’ve probably come across colorimetric gas detection tubes. They go by several names: stain tube detectors, chemical detector tubes, or simply by their brand …
Your portable gas monitor spends its working life in one of the dirtiest environments imaginable, clipped to your collar in confined spaces, dusty plants, and greasy mechanical rooms. And because it has to sit inches …
