ORP Redox Meter Digital Type for Water Quality Testing Potential Range

Digital Tester 169E ORP/Redox Tester ORP Tester Potential Positive and Negative ORP Meter Tester Meter FG05Oxidation-Reduction Potential ORP is an abbreviation that represents the oxidation potential of the solution. ORP value is a measure of the ability of the redox solution, the unit is mV. ORP meter is special equipment for testing solution redox potential.The instrument enclosure adopts waterproof design, waterproof rating of IP55. The electrode can be replaced.With data lock function to facilitate the measurement and recording of data stored; Negative potential (O.R.P) penThe introduction of advanced technology and components, greatly reducing the volume, reduce costs, maintain the original quality, so the use of ORP gained popularity. compatible with functional energy water purifier and negative potential energy cups and other needs of the determination of the value of having a negative potential.The main technical indicators: Measuring range: 0 ~ +/- 1999mV; Resolution: 1mV; Accuracy: +/- 5mV; Battery: 4 x 1.5V (-13 batteries) not included; Operating Temperature: 0 ~ 50°C; Calibration: 1 point calibrationProcedure:1.Remove the protective cover.2.Contact the "ON/OFF" switch to power on.3.Place the electrode in the test solution and gently shake until the display value is stable then read the value.4.Contact the "HOLD" key, then keep the value of the current measurement. If you need to re-measure, press the "HOLD" button to automatically release the hold.5.After use, press the off switch, wash the electrode with distilled water, put on the protective sleeve.Battery installation: If the display is blurry or no display, you should change the batteries. When replacing the battery, unscrew the cover, replace the battery, pay attention to the battery polarityCALIBRATION:1.Immerse the meter in the distilled water. Activate it after a few hours.2.Immerse the meter in the calibration solution. And stir it gently.3.Regulate the trimmer with a screwdriver until the LCD screen shows 265mV.4.Rinse the electrode with distilled water, and suck it dry with filter paper.colour: white + greenMaterial: ABS + electronic componentsSize: 18.8cm x 3.5cm x 3.5cmPackage Contents:1 x 169E ORP Tester1 x English manual
