How to Measure CO2: Indoor Air to Process Control
Carbon dioxide is the one gas where the measuring principle is effectively settled: it does not burn, it is not electrochemically convenient, and it absorbs infrared light strongly at 4.2 µm. That leaves non-dispersive infrared absorption as the practical method across every application from a classroom to a fermentation tank.

Methane Detection Explained: LEL, %vol and ppm Ranges
Methane is measured in three different units, and each answers a different question. ppm asks "is there a leak?", %LEL asks "is this atmosphere about to explode?", %vol asks "how much gas is in this pipe?".

Do Infrared Gas Sensors Get Poisoned? NDIR vs Pellistors
An NDIR sensor measures how much infrared light a gas absorbs, so nothing in the gas stream touches a catalyst and nothing is consumed. A catalytic bead sensor, by contrast, burns the gas it measures on a catalyst surface - and that catalyst can be poisoned, inhibited or burned out.

Catalytic vs NDIR Methane Sensors: Which Is Better?
Methane (CH₄) monitoring is a key element of industrial safety, environmental control, and process supervision. Due to its flammability and wide explosive range, methane requires continuous and reliable concentration measurement in both confined and open industrial environments. In addition to explosion hazards, methane emissions are subject to increasing regulatory control because of their environmental impact.

Gas Detection in Mines: Why CH₄ Sensors Are Critical
Underground mining remains a high-risk industrial activity, where methane (CH₄) is one of the primary safety hazards. This colorless and odorless gas can accumulate unnoticed and form an explosive atmosphere at relatively low concentrations, making continuous monitoring essential for safe operation.

Industrial Use of Propane Gas Sensors
Propane (C₃H₈) is widely used in industrial facilities as a fuel and process gas, particularly in LPG storage, manufacturing, and chemical operations. Due to its flammability and tendency to accumulate near the ground, uncontrolled propane leaks represent a serious explosion and fire hazard.
-
Propane Gas Monitoring in Storage Facilities
Propane (C₃H₈) is widely stored and handled at industrial LPG terminals, tank farms, and distribution facilities. Due to its flammability and higher density compared to air, uncontrolled propane leaks in storage areas present a significant explosion and fire hazard, especially in confined or poorly ventilated zones.

Gas Sensors for Warehouses and Logistics Centers: Why They Matter
One forklift malfunctions in a closed storage area. One unnoticed propane (C₃H₈) or methane (CH₄) leak from equipment, or a rise in carbon dioxide (CO₂) levels in a poorly ventilated space — that's all it takes to put workers at risk. Installing the right gas sensor is not optional — it's a basic part of operational safety.
