New Sensors for Ammonia Gas Detection - International Gas ...

· The Challenge for Ammonia Gas Detection. Ammonia gas is classed as a toxic gas under COSHH regulations and therefore you will require an ammonia gas detection system to monitor the atmosphere to comply with COSHH. However, one of the main downfalls of current ammonia gas sensors is that they don’t really fit the bill, especially for refrigeration plants.
