What Specifications of the  digital ORP water meter:

This ORP meter is a pen-type device to measure the amount of Oxidation Reduction Potential (ORP) level in sample quickly and conveniently. ORP is a tendency of the solution to either gain or lose electrons. The backlight LCD equipped enables users to do testing and measurement even in dark fields.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 microorganism is killed (oxidized).

Functions of the digital ORP water meter pen

ORP is correlated with the quality and purity of water. ORP meter has a wide range of applications in water sources, aquarium, hydroponics, spas, swimming pools and other water systems!


Warm Notes!!!

1,  Switch on the ORP Meter , and immerse the electrode in the distilled water for few hours .

2,  Immerse the electrode in 256mV calibration solution (4.01 calibration solution of quinhydrone 

     reagent), stir the meter gently.

3, Wait till the reading is stabilized , and adjust the reading to 265mV by pressing the potentiometer 

    with the screwdriver.

4,  Rinse the electrode with distilled water .


NOTE: Keep the electrode immersed in Potassium Chloride Solution for few hours for every 15days can maintain the accuracy of the ORP Meter..
