General Monitors IR2100 Gas Detector

Feature & Principle

It is an NDIR infrared point gas detector for hydrocarbon gas. It adopts dual-beam single detector infrared absorption principle. The infrared light passes through the gas chamber, hydrocarbon gas absorbs specific wavelength infrared light, the circuit compares reference beam and measuring beam signal to calculate gas LEL concentration. It is not easy to be poisoned, supports continuous monitoring, Modbus digital communication and relay alarm output.
