Nitric Oxide (NO) Detectors

We supply fixed nitric oxide gas detectors from leading brands including BW, Crowcon, Dräger, GMI, Green Instruments, Honeywell, MSA, and RAE Systems. These detectors are designed to provide continuous, accurate monitoring, ensuring safe working conditions and regulatory compliance.

Protect your workforce with reliable NO gas detection solutions.

Exposure to Nitric Oxide can cause lung irritation, coughing, shortness of breath, and long-term respiratory damage, especially when combined with NO₂. Industrial workers in power plants, refineries, and manufacturing sites are particularly at risk.

Nitric Oxide (NO) is a colourless, highly reactive gas commonly found in industrial combustion processes, chemical manufacturing, and metallurgical operations. In the atmosphere, it rapidly oxidises to Nitrogen Dioxide (NO₂), contributing to air pollution and respiratory health risks.
