非分散红外一氧化碳分析仪
Tunnels, car parks and traffic corridors are where carbon monoxide monitoring matters most, and this NDIR analyzer with gas filter correlation is built for that work. It reads at 4.6 µm with a 0.04 ppm detection limit and a cell held at 50 °C. Select 0–50 or 0–200 ppm depending on whether the site is urban background or near traffic.
