What is a portable infrared gas analyzer and how does it work?
A portable infrared gas analyzer is a handheld or portable device that measures multiple industrial gases such as CO, CO₂, CH₄, CnHm, O₂, and H₂ using NDIR non-dispersive infrared sensors, electrochemical cells, and MEMS thermal conductivity detectors. It provides rapid, accurate, and interference-resistant readings pour industrial safety, combustion monitoring, and environmental compliance.
How fast can a portable NDIR gas analyzer measure gases?
Moderne analyseurs de gaz portables NDIR like Instrava’s model can complete measurements in less than one minute, with a response time (T90) ≤15 seconds. This allows engineers and safety personnel to quickly detect gas concentrations and make immediate process or safety decisions.
Which gases can a portable infrared gas analyzer detect?
A standard portable infrared gas analyzer detects CO, CO₂, CH₄, CnHm, O₂, H₂, and calculates high/low calorific values. Optional configurations allow custom measurement ranges or additional gases without increasing costs, making it versatile for laboratories, industrial flues, boilers, and kilns.
Can a portable infrared gas analyzer operate in harsh industrial environments?
