Product Description
4-in-1 water quality meter--It can measure TDS/EC/pH/Temperature. The measurement range is large and wide. Pocket-sized and multi-functional, Ideal for household and laboratory pH testing applications, including drinking water, swimming pool, pond, beer brewing, kombucha, aquariums, hydroponics, laboratory, food processing, etc.
Details determine quality
Three-point calibration function
It adopts three - point calibration (PH4.00/PH6.86/PH9.18).
In the normal measurement state, long - press the down key, and the instrument enters the calibration mode, and the screen displays CAL.
1.Pour the standard buffer solutions with pH values of 4.00, 6.86, 9.18 and distilled water into different clean cups respectively.
2.For accurate calibration, for each buffer solution, use two cups for sub - packaging. One cup is filled with clean water to rinse the electrode, and the other cup contains the solution for calibration.
3.Gently press the "power key" to turn on the power.
4.Put the electrode into the pH4.00 standard solution and shake it gently until the value stabilizes.
5.Press and hold the "CAL" key for about 5 seconds and then release it. The instrument enters the automatic calibration state until the displayed value is consistent with the pH value of the standard buffer solution at this temperature, that is, the pH4.00 point calibration is completed.
6.Clean the electrode, dry it, put the electrode into the next standard buffer solution, and shake it gently until the value stabilizes.
7.The measurement methods for pH6.86 and pH9.18 are the same as those for the pH4.00 standard buffer solution.
Warm tips
1.If there is no operation on the keys for 5 minutes, the instrument will automatically turn off to extend the battery life.
2.The immersion height of the pen tip in the solution should be lower than the maximum water level line to avoid affecting accurate readings.

Test before drinking, identify water quality with a single test.The TDS value represents the concentration of dissolved solids in water.The lower the TDS value, the fewer dissolved solids in the water, and the purer the water quality.The higher the TDS value, the more dissolved solids in the water.However, it cannot determine whether these substances are harmful!
Note: The TDS value is just one of the water quality indicators. The quality of water cannot be judged solely based on the TDS value. According to the Standards for Drinking Water Quality, a qualified TDS value should be ≤1000.
