QR Code Link to This Post
&Gt ;& Gt; This ORP meter is a pen type device to measure the amount of Oxidation Reduction Potential (ORP) level in sample quickly and conveniently. & Gt; & Gt; ORP is a solution trend to gain or lose electrons. Equipped LCD backlight allows users to test and measurement, even in dark fields. & Gt;≫ 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 measured in millivolts (mV). The more positive the ORP value, the higher the disinfecting power of water, therefore the faster the microorganism dies (rusts). ≫≫ ORP correlates with water quality and purity. Metro ORP has a wide range of applications in water sources, aquarium, hydroponics, spa, swimming pools and other water systems. ≫≫≫ Specification: * Range : 0 ~ ± 1999 mV. * Accuracy : ± ; 5 mV. * Resolution: 1 mV. * LCD display: 4 digits. * Operating temperature: 0 - 50C. * Calibration: by mini screwdriver (included). * Clear LCD with backlight. * Compact and portable pen design. * Easy to use and provides instant display of results. ≫≫≫ Calibration Method: 1-Turn on the ORP Meter and immerse the electrode in the distilled water for a few hours. 2-Dip the electrode into a 256 mV calibration solution (4.01 calibration solution of quinhydrone reagent), gently shake the meter. 3-Wait until the reading is stabilized, and adjust the reading to 265mV by pressing the potentiometer with the screwdriver. 4-Rinse the electrode with distilled water. Ideal for water, spa, pool, aquarium, hydroponics, etc.
