The Fermion MEMS Ammonia NH3 Gas Detection Sensor. This sensor is great for keeping track of ammonia levels in different places.
It’s small, measuring just 13 x 13 x 2.5mm, so it fits easily into your systems. It uses very little power-less than 20mA-helping you save on energy costs. Plus, it heats up quickly and gives fast readings, so you can rely on it when you need to check the air.
You can use this sensor to find ammonia leaks in cold storage, manage risks in fish farming, or monitor odors in bathrooms. If you’re looking for a reliable way to ensure safety and keep the air fresh, the Fermion MEMS NH3 Sensor is a perfect choice.
