What Makes Infrared (NDIR) Gas Detection So Reliable?

Infrared gas detection has become increasingly popular due to its stability, accuracy, and low maintenance requirements. Unlike catalytic sensors, infrared detectors do not rely on chemical reactions. Instead, they measure how much infrared light is absorbed by a gas at specific wavelengths. Each gas absorbs IR radiation differently, allowing the sensor to identify and measure […]

Understanding the Basics of Catalytic Bead Gas Sensors

Catalytic bead sensors are one of the oldest and most trusted technologies for detecting flammable gases. Despite the emergence of infrared detection, catalytic sensors remain widely used because of their reliability and affordability. The basic principle behind these sensors is simple: when a flammable gas comes into contact with a heated catalytic element, it oxidizes […]
