Nitrogen Dioxide (NO2) Detectors

We supply fixed Nitrogen Dioxide gas detectors from trusted manufacturers including Bacharach, BW, Crowcon, Dräger, GMI, Green Instruments, Honeywell, MSA, RAE Systems, Riken Keiki, Senko, and Uniphos. These detectors deliver continuous real-time monitoring, ensuring worker safety and compliance with international safety standards.

Safeguard your operations with reliable NO₂ monitoring solutions.

In the workplace, NO₂ exposure can cause eye and throat irritation, lung inflammation, and long-term respiratory illness. High concentrations may lead to pulmonary edema, making accurate detection essential in industries such as power generation, refineries, automotive workshops, and confined spaces.

Nitrogen Dioxide (NO₂) is a toxic, corrosive gas produced mainly by combustion processes, vehicle exhausts, welding, and chemical manufacturing. It is one of the most significant air pollutants, contributing to smog and acid rain.
