Ammonia NH₃

Ammonia (NH3) is a critical gas in various industrial processes, particularly in agriculture, chemical manufacturing, and environmental monitoring. Its ability to contribute to environmental pollution, especially in the form of particulate matter and as a precursor to nitrous oxide, makes its effective monitoring crucial for compliance with environmental regulations and to ensure worker safety.

At Signal Group, we specialise in advanced gas analysers designed to provide accurate, reliable, and continuous monitoring of ammonia emissions. Our state-of-the-art technology is tailored to help industries not only meet regulatory standards but also improve process efficiency and environmental performance.
