Hi,

Are there any ammonia sensor in the market?
Not looking at ammonia test kit.

Thanks

Yes. Seachem Ammonia alert.

life span for it is 6 mth for freshwater. works only if PH is greater than 7.0 A little too expensive I should say.

It is worth to note that the detector detects only free ammonia. Therefore, it is more suited for marine aquarium where pH is higher and most of the ammonia is in the free form.

In fresh water, where pH is neutral or acidic, ammonia exist mostly as ammonium ions (NH4+). Therefore, the detector will detect very low level or not detect at all.

Thanks for all the comments/feedback.

Just like what bro bclee says, the seachem sensor is only good for tanks with pH above 7 or in the alkaline medium, Usually not suitable for fresh water. While tose test kits only measue total ammonia, ie both NH4+ and NH3.

I am wondering if there are electronic ones, like the pH sensor, those which work with a probe and you take readings from a meter.
