Product Introduction
I. Introduction to the infrared carbon dioxide sensor (NDIR CO2 sensor) IRC-AT:
UK Alphasense is a professional manufacturerGas Sensormanufacturer, developed small sizeInfrared CO2 gas sensorUses non-dispersive infrared (NDIR) technology to detect gases. Based on the different absorption rates of infrared spectra by different gases at different concentrations, it detects the presence and concentration of target gases. It is not easily affected by harsh on-site environments. It adopts dual-channel sampling technology, which can self-suppress zero drift. It features long calibration cycles, strong anti-interference capability, high accuracy, high reliability, and long service life.
