pH & ORP controller for hydroponic:

Hydroponic systems could better diagnose problems and better understand the evolution of their hydroponic crops. Automating measuring instruments are not only having sensors that can take readings at predefined intervals but also making sure that the reading from these sensors are stored so that they can be used for analysis and diagnosis later on. 

It provides reliable dosing when required to maintain a constant pH level in a hydroponic system. And alarm function and relay to keep the requirement value.

If you want to perform automated monitoring then you would definitely want to buy pH, ORP, ambient temperature, solution temperature, humidity and carbon dioxide sensors. We can also provide other instruments to you.

pH & ORP controller for water treatment:

Wastewater treatment often consists of removing heavy metals and/or organic compounds from effluent streams. pH adjustment by addition of acidic/basic chemicals.

At an acidic pH the excess of positive hydrogen and metal ions have nothing to bond with and float around in the water, never settling. At a neutral pH the hydrogen ions are bonded with the hydroxide ions to form water while the metal ions remain. At a basic pH the excess hydroxide ions bond with the metal ions to form metal hydroxides which can be removed through filtering or settling. In addation the pH of water can be used to kill off bacteria in wastewater.
