YINMIK pH Meter with Flat Surface Electrode to Measure pH of Liquids Semi-Solids e.g. Hydroponic Nutrient, Wort in Beer Brewing, Lotions and Creams Cosmetic, Durable Tester with Protective Sensor Cap

  • ...INMIK flat probe pH tester resists breaking and prevents junctions from becoming clogged, which is easy to use and convenient for cleaning. In addition, attributed to the flat surface electrode, this pH meter performs excellently when measuring pH of small volume samples..
  • [Easy to Calibrate] Supporting 3-point auto calibration, following the instruction manual can easily achieve 4.00, 7.00, 10.01 auto calibration. Don't worry about the calibration solution, you can easily configure up to 500ml of calibration solution for each standard using the calibration powder included in the package. In addition, you can also purchase calibration powder from the YINMIK store on Amazon at an affordable price..
  • [Long life span] The protective cap of the tester contains a wet sponge soaked in KCL solution, making the probe always moist, and that gives the tester more durable life. This design avoids the problem of most other products where the electrode is directly exposed to air, thus causing the reference electrode to dry out and the pH tester to fail to read accurate values..
  • [User-friendly Design] The long electrode design can measure the pH value of solutions in deep containers, which is very convenient in hydroponics, laboratory, fermented food preparation,....
