• Waterproof ORP Meter PH Tester three in 1 ORP TEMP PH Meters Redox Potential Testers Water Quality Measure Tool Water Detector For this ORP TESTER, it doesn't includes calibration liquid,the one you get possibly now not accurate,In order to ensure the accuracy of this item pls make calibration once you get the parcelThis gadget is often utilized in dimension of Water Disinfection, the stronger the ORP, the faster the microbe is killed Oxidation Reduction Potential (ORP) was found to be a competent indicator of bacteriological water high quality has protective cap that helps reduce contaminationClear LCD with backlight functionProvides instantaneous exhibit of measured valueCompact pensize and light weight for mobilityNote: this product come without retail field and battery Specification:Measuring range:PH：0 pH, ORP:-1999-1999mV, Temp:0-50℃Resolution:PH:0, ORP:1mV, Temp:0℃Accuracy:PH:±0, ORP:±5mV, Temp:±1℃Automatic Temperature Compensation:0℃-50℃Battery Type:4×1(AG13)(Not Included)Operating Temperature:0℃-50℃Calibration:Manual,at one level through trimmerDimensions:188mm×35mm×35mmWeight:98gOperation:1 the protective cap on the meter rinse the electrode with distilled water,and suck it with filter-paper the electrode within the method to be tested gently and watch for the reading to stabilize now not faucet it against the glass the "pH/ORP" button,choose the PH or ORP for measuring the "C/F"button to modify between Celsius and Fahrenheit use,turn off the meter the electode wth disilled water to mininmize contamination replace the protecting cap after use:1)PH1 the ph electrode first with distilled water,and suck it with filter out paper at the meter Press the "pH/ORP"button,choice the PH for measuring the ph electrode in pH6(or pH7)buffer solution,gently shake the meter and look forward to a steady demonstrate the trimmer with the screwdriver supplied until show shows "6"("7")at buffer answer temperature of 25℃ the ph electrode with distilled water,and suck it with filter out paper (not included) the pH electrode in pH4 or pH9(pH10)buffer solution,gently shake the electrode and looking ahead to the reading to stabilize displaying value and buffer solution&;s ph value is inside error vary calibration of the instrumen&;s pH range is now complete:The ph meter ought to be recalibrated below following situations;The meter has been used for very long time because the last calibration or useThe meter has been utilized in specifically continual conditions utmost accuracy is required)ORP1 on the meter the"pH/ORP" button,choice the ORP for measuring the electrode with distilled water the electrode into the brand new 256mV ORP ordinary solution,then stir it gently,4)Allow the studying to stabilize and with a small screwdriver turn the calibration trimmer till the display shows"256")Rinse the electrode with distilled water and suck it with filter out paper)Switch off the meter the battery compartment cap calibration of the instrument&;s ORP differ is now whole replacement:1 the protective cap the plastic ring on the peak of the electrode out the electrode and replace it with a new one sure the gaskets are in place before screwing back the hoop
