• Waterproof ORP Meter PH Tester 3 in 1 ORP TEMP PH Meters Redox Potential Testers Water Quality Measure Tool Water Detector For this ORP TESTER, it would not entails calibration liquid,the one you get possibly now not accurate,In order to guarantee the accuracy of this item pls make calibration once you get the parcelThis machine is commonly utilized in size of Water Disinfection, the stronger the ORP, the speedier the microbe is killed Oxidation Reduction Potential (ORP) changed into stumbled on to be a competent indicator of bacteriological water high quality has protective cap that supports lower contaminationClear LCD with backlight functionProvides on the spot display of measured valueCompact pensize and lightweight weight for mobilityNote: this product come without retail box 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 point through trimmerDimensions:188mm×35mm×35mmWeight:98gOperation:1 the protecting cap on the meter rinse the electrode with distilled water,and suck it with filter-paper the electrode in the option to be tested gently and watch for the studying 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 paper on 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 await a stable exhibit the trimmer with the screwdriver supplied till display shows "6"("7")at buffer solution temperature of 25℃ the ph electrode with distilled water,and suck it with clear out paper (not included) the pH electrode in pH4 or pH9(pH10)buffer solution,gently shake the electrode and waiting for the reading to stabilize showing value and buffer solution&;s ph price is within error range calibration of the instrumen&;s pH fluctuate is now complete:The ph meter ought to be recalibrated below following situations;The meter has been used for very long time since the final calibration or useThe meter has been used in specifically continual circumstances 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 common 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 paper)Switch off the meter the battery compartment cap calibration of the instrument&;s ORP differ is now whole replacement:1 the protecting cap the plastic ring at the top of the electrode out the electrode and update it with a brand new one yes the gaskets are in position earlier than screwing again the ring
