KPH500 Ph Sensor Ph0-14 Ph Test Sensor Module Water Quality Probe Ph water quality monitoring equipment
Production Introduction
The PH/ORP meter is a precision meter used to detect the pH/oxidation-reduction potential of liquids. It is designed with a microcomputer based on the principle of the primary battery and is simple to operate and easy to maintain. Not affected by color, turbidity, colloidal substances, oxidants and reducing agents, it is suitable for the determination of various media such as clean water, wastewater, industrial water, chemical reagents, etc., and is widely used in agriculture, environmental protection and industry.
The sensor uses a composite electrode, which can eliminate the influence of the inconstant "K" value,
A long-term, stable and accurate measurement of PH is realized. The internal structure of the sensor is shown on the right.

Q&A
How is ORP calculated?
ORP is determined by measuring the potential of a chemically-inert (platinum) electrode which is immersed in the solution. The sensing electrode potential is read relative to the reference electrode of the pH probe and the value is presented in millivolts (mV).2015年11月19日
How do I lower my ORP?
Factors that can lower ORP in pools.
In pool water chemistry, once added to the water all chlorine oxidizers, including salt, produce hypochlorous acid (HOCl), hypochlorite ions (OClᐨ) and a by product specific to the type of chlorine being used.2019年2月15日
Does pH affect oxidation?
The dissolved oxygen concentration increases and because the reaction in the broth is an oxidation process, the redox is also increasing. Oxidation also increases with pH decreasing but why? When I am supplying oxygen for a long time, redox decreases as well as the pH also behaves the same way.
How can I lower my water ORP?
Lowering the pH to 6.0 raises the ORP, as more hypochlorous acid (HOCl) becomes available. Raising the pH to 8.0 lowers the ORP value, as more hypochlorite ions (OCl–) are present. Maintaining constant pH but adding more chlorine raises the ORP to a plateau of 900 to 950 mV, generally around 25 ppm HOCl.
What is pH?
pH is a measure of how acidic/basic water is. The range goes from 0 to 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. The pH of water is a very important measurement concerning water quality.
