Ammonia/pH Aqua Sensor – Pacific Sentry

The Ammonia/pH sensor enables visual monitoring of toxic ammonia (NH3) and pH levels in aquaria water on a continuous basis. Simply attach it in a visible location with both sensor pads completely immersed. With initial use, wait 15 minutes for the NH3 sensor to hydrate and up to 24 hours for the pH sensor to hydrate before making first reading.

Ammonia, Nitrite and Nitrate Probes? Sensors Arduino Forum

· Hello, I am looking for probes for determining the amount of ammonia, nitrite, and nitrate present in a liquid. Specifically, I''m looking for something I can use to monitor (not adjust, just monitor) the chemical status of my fish tank. Googleing hasn''t found me anything but the MQ137 which is a gas sensor for ammonia, not liquid.

New range of ionic ammonia sensors Envirotech Online

· Current electrochemical sensors are generally only specified to 20 Deg C. Current electrochemical sensors require water vapour to operate. This means, long term performance in an environment around 20 ℃ will not be good for electrochemical sensor. At 20 degrees centigrade there is little water vapour in the air for the ammonia gas detector to operate. A current alternative is to use ...

Ammonia Ammonium Water Quality Parameter Overview …

Ammonia is a colorless, pungent gaseous compound of hydrogen and nitrogen (one nitrogen atom and three hydrogen atoms, NH 3) that is highly soluble in water. Ammonia is formed naturally as a product of the microbiological decay of nitrogenous organic matter (animal and plant protein). It can also be produced for use in fertilizers, or for use ...
