Redox Potential Meter Digital ORP Tester for Water Quality Testing

169E ORP/Redox Tester ORP Tester Potential Positive and Negative ORP Meter Tester Meter FG05 Oxidation-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 test solution redox potential of special equipment. The instrument enclosure 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 pen The 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; Calibration: 1 point calibration Procedure: 1. Remove the protective cover. 2. Press the ON/OFF switch to power on. 3. Place the electrode in the test solution and gently shake until the display value is stable before reading. 4. Press the HOLD key to keep the value of the current measurement. If you need to re-measure, press the HOLD button again to automatically release the hold. 5. After use, press the off switch, rinse the electrode with distilled water, and put on the protective sleeve. Battery installation: If the display is blurry or fails to display, you should change the batteries. When replacing the battery, unscrew the cover to replace it, pay attention to the battery polarity CALIBRATION: 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 LCD screen shows 265mV. 4. Rinse the electrode with distilled water, and dry it with filter paper.
