Still maybe does ok the first poultry barn we wear it in, but after that it gets lower and further off from right in every barn after. And it always goes back to zero good when we go between the 6 barns. For a meter to do a good job consistently, it has to have a pump so it gets the same airflow all the time. Even when this one seems like it is working, it reads higher when walking then standing still. ## Features - ⚛️ ACCURATE: Ammonia (NH3) gas detector using electrochemical sensors, 0 - 100 ppm with 0.1 ppm resolution.

There are hardwired units with alarms that would probably be a wiser choice. That’s my 2 cents **Q: Can i use for aquarium?** A: No, only for gas or air environments. **Q: Can you use in fish tank, pond** A: No, its for measuring ammonia in the air, like you might find in a poultry farm. I think there are test strips or kits available for measuring ammonia en water. **Q: Is the pump and probe sold separately required for measurement?** A: No, the meter will respond to ammonia en the air surrounding it. However, if you want to check the concentration in a confined space before entering, the pump and probe would be necessary. ## Customer Reviews ### ⭐ Wouldn't depend on this for life safety *by B***H on March 3, 2026* Thought it worked okay during the first flock we had it.
