High Precision ORP/Redox Meter, for Digital Tester 169E

Oxidation-Reduction Potential ORP is an abbreviation that represents the oxidation potential of the solution.<br> Digital Tester 169E ORP/Redox Tester ORP Tester Potential Positive and Negative ORP Meter High Precision Tester Meter f54<br> ORP value is a measure of the ability of the redox solution, the unit is mV.<br> ORP meter test solution redox potential of special equipment.<br> The instrument enclosure waterproof design, waterproof rating of IP55.<br> The electrode can be replaced.<br> With data lock function to facilitate the measurement and recording of data stored; Negative potential (O.R.P) pen<br> The introduction of advanced technology and components, greatly reducing the volume, reduce costs, maintain the quality, so the use of ORP gained popularity.<br> Procedure:<br> 1.Remove the protective cover.<br> 2.Contact the "ON/OFF" switch, power.<br> 4.Contact the "HOLD" key, then keep the value of the current measurement.If you need to re-measure, then press the "HOLD" button is automatically released on hold.<br> 5.After use, press the off switch, the electrode with distilled water, put on protective sleeve.<br> CALIBRATION:<br> 1.Immerse the meter in the disilled water.Activate it after a few hours.<br> 2.erse the meter in the calibration solution.And stir it gently.<br> 3.Regulate the trimmer with a screwdriver until LCD screen for 265mV.<br> 4.Rinse the electrode with distilled water, and suck it with filter paper.<br> 1 x 169E ORP Tester<br> 1 x English manual<br> Intended for functional energy water purifier and negative potential energy cups and other needs of the determination of the value of having a negative potential.<br> Colour: white + green<br> Material: ABS + electronic components<br> Size: 18.8cm x 3.5cm x 3.5cm<br> The main technical indicators: Measuring range Range: 0 ~ +/- 1999mg/LmV; Resolution Resolution: 1mV; Accuracy: Accuracy: +/- 5mV; Voltage Battery: 4 x 1.5V (-13 batteries) not included; Operating Temperature Operating Temperature: 0 ~ 50; Correction Calibration: 1 point calibration<br> Included in the package:<br> Only the listed package contents are included.<br> 3.Place the electrode in the test solution and gently shake until after the show read the display value is stable.<br> Battery installation: If the display is blurry or display, you should change the batteries.When replacing the battery, unscrew the cover, can be replaced, pay attention to the battery polarity<br> Note: Actual colour may vary slightly because of lighting and display settings.<br> Please allow a measurement tolerance of +/- 1-3cm.
