Measurements of ORP are fundamental to water and liquid quality, and this pocket ORP meter offer high reliability and accuracy at a very affordable price. It measure the amount of Oxidation Reduction Potential (ORP) level in a solution. ORP is a tendency of the solution to either gain or lose electrons. Oxidation is defined as the loss of electrons in a molecule, atom or ion. An oxidizing agent (e.g.Chlorine and Ozone) is a substance that acquires electrons in a Redox reaction. ORP is a potential which is measured in millivolts (mV). The more positive the ORP value, the greater the power of water disinfection, thus the faster the micro organism is killed (oxidized).

ORP or Oxidation Reduction Potential is commonly used in measurement of Water Disinfection and is correlated with the quality and purity of water. This meter allows calibration and offers highly reliable measurements and has a wide range of applications in Aquarium, Hydroponics, Spas,Swimming pools and other water systems.
