Can this unit be left on continuously and once it detect amonia an alarm will sound?

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

Can i use for aquarium?

No, only for gas or air environments.

Can you use in fish tank, pond

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.

Is the pump and probe sold separately required for measurement?

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.
