7-in-1 pH Meter: The pH meter is designed with a 7-in-1 function, which can measure pH (acidity and alkalinity), EC (conductivity), TDS (total dissolved solids), Salinity (salt content), S.G, ORP (Oxidation-reduction potential) and temperature. Simply press the {MODE/CAL} key to switch the value of pH, EC (uS/cm), TDS (ppm), Salinity (ppm/%), S.G, ORP (mV).

Easy to Use: Simply immerse the pH meter electrode in the solution to be tested, pH values are quickly displayed on a large LCD display. Simply press the {HOLD/TEMP} button to lock the measured value and then take it out for viewing. Also, long press the {HOLD/TEMP} button to switch temperature units.

3 Salinity Test Application Ranges: Salinity Test (0-9999ppm), Seawater Test (10-200ppt), (1ppt=1000ppm, when the ppm number exceeds 9999ppm, the pH meter will automatically switch to the ppt unit display). Food test (0.01-25%). When testing food, select the appropriate measurement mode and unit to ensure accurate and reliable measurement results. The units of TDS and salinity are the same, but when measuring salinity, the pH meter needs to be converted to salinity mode.

Automatic Temperature Compensation: Digital pH meter can accurately measure the pH value of the sample within the temperature range of 0℃-60 ℃ (32°F-140°F), which can perfectly solve the error caused by the liquid temperature change, thus making the PH value more accurate.

Wide Application: The 7-in-1 pH tester is suitable for testing household drinking water, hydroponics, swimming pools, aquariums, laboratories, etc. The salinity tester has multiple uses, not only detecting the salt content of edible salt, saltwater ponds, and koi ponds, but also detecting the salinity of seawater, oceans, and saltwater fish ponds.

The multi-functional 7-in-1 tester can easily measure multiple parameters, it can measure pH/TDS/EC/ORP/Salinity/S.G/Temperature. The measurement range is large and wide, and it can measure freshwater salinity and sea salt. It is suitable for drinking water, aquariums, swimming pools, and seawater.

How to Calibrate the pH Meter?

1. Before calibration, prepare 3 beakers containing separately 250ml of pH 4.00/pH 6.86/pH 9.18 standard solution.

2. Rinse the electrode with clean distilled water and wipe it dry. Turn on the pH meter and adjust to pH mode.

3. Immerse the electrode into the pH6.86 buffer solution, wait for the value to stabilize, press "CAL" for 5s, and the screen will display "CAL", when pH6.86 flashes 3 times, the calibration of pH6.86 is finished.

4. Repeat the above steps to calibrate pH4.00 or pH9.18.

Q : Does the package deliver calibration objects?
A:Please note that the package only distributes 3 packs of PH calibration powder. Other calibration liquids need to be purchased by you. The products have been calibrated before leaving the factory, and you can use them directly.

pH Reset
1.Shut-off HOLD/TEMP and MODE/CAL simuiltaneously,don't release;
2.Press ON/OFF and release all buttons,reset is finish.

P-3 model reset
1.Put battery out press TEMP/CAL and HOLD simultaneously.don't release;
2. Put battery on,and release all buttons,reset is finish

1.It has been calibrated by factory,use it directly;
2.After finished,clean the electrode with pure water and keep it dry
3.Stir gently several times to ensure no air bubble around the electrode;
4.Don't disassemble the meter without permission to avaid damage;
5. Keep it dry.

Calibration :
1.EC:Recognize solution automaticly ( 1413us/cm, 12.88mS/cm , 111.8m5/cm) --f the meter can't identify the solution,change the electrode or contact supplier
2.pH: One point or two points or three points automaticly------f the meter can't identify the solution,chare the electrode or contact supplier
3.Noted:Always clean the electrode after use
If the pH calibration cannot identify the solution, the electrode is broken
