## Questions & Answers

**Q: Can this unit be left on continuously and once it detect amonia an alarm will sound?**
A: It can, but really would rely on a battery powered unit for any kind of life safety application.  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.
