Troubleshooting Tip: You can decide how many calibration points you use (one, two or three points). The meter automatically detects the calibration solution used. The pH 7.00 solution must always be used as the first calibration point. The meter has a self-diagnosis function. "Er1" is displayed: when the reading exceeds the detectable range of the meter. "Er2" is displayed: the measurement was not stable when you pressed [Cal]. Wait for [Smiley] when measuring, before pressing [Cal]
NOTE: If you find white crystals inside or outside the electrode cap, this is completely normal. It is the 3M KCl that crystallizes over time. Simply rinse it and use the gauge as usual
Large LCD displays pH, temperature and calibration status
Easy calibration with automatic buffer detection
Complete set including calibration solutions, batteries and lanyard in a handy carry case
Automatic temperature compensation (ATC) (in the range 0-50°C)
ATTENTION: water droplets are added during production to maintain the moisture of the electrode. A damp electrode cap does not mean that the product has already been used

TDS Tester for Hydroponic Base Water - Understanding the pH requirements of specific plants is crucial for optimizing hydroponic systems. Different plants have specific pH preferences and most nutrient solutions generally have a pH value between 5.5 and 6.5. To ensure the stability of the hydroponic system, it is recommended to monitor and adjust the pH value regularly.
PH TESTER WITH HIGH SENSITIVE PROBE - The pH tester has a high sensitivity probe with a resolution of 0.1 and a full measurement range of 0-14 pH. There is also a sponge cap that keeps the electrode moist and thus extends the life of the probe. The easy-to-read display with green backlight allows quick readings in low light conditions and automatically shuts off after five minutes of inactivity to charge the battery
Multifunctional 4 in 1 pH Tester: Our digital GIDIGI pH testers are versatile and can measure not only pH values, but also TDS, EC and water temperature. With a wide test range for pH (0.1-14.0), EC (0-9990μS/cm, 10.01-19.99mS/cm), TDS (0-9990ppm) and temperature (32.0-140.0℉, 0.0-60.0℃), it is perfect for various applications such as hydroponics , aquari, aquari, aquari, swimming pools, tap water, hot tubs and brews.
Display hydroponic pH and ppm value together: our pH tester can simultaneously measure the pH value and ppm of the hydroponic solution.

[For Hydroponics Stable] UIUZMAR water pH tester is equipped with a special chip, which makes the pH test result exceptionally stable and fast. You no longer have to wait for the display to jump anywhere. If you are creating a hydroponic plant or maintaining a tower garden (aeroponics garden), you can ensure that your garden receives the right type of water it needs to thrive.
[For Hot Tubs: Practical] UIUZMAR digital pool water pH meter is equipped with a large LCD display for easy reading, you don't need test strips in matching color and the size of the pH meter is just right, very easy to carry. You can use it to test the pH of hot tub water and saltwater pool water if you are a serious pool owner, because a balanced pH is essential for a healthy and clean swimming pool.
[For Aquarium Water:Accurate] UIUZMAR pH Water Tester indicates both pH and temperature. The automatic temperature compensation function (ATC) ensures that an accurate pH is always obtained no matter where or when you use it. With the UIUZMAR aquarium pH meter, you can quickly and accurately test the pH of your freshwater aquarium without having to do drop tests and have a general idea of the number. That's why the UIUZMAR aquarium pH meter is the right choice.
[Digital pH Meter for Many Purposes] With the UIUZMAR water pH meter, you can test the pH of your hot tub, check the pH of freshwater aquariums, record pH values for horticultural purposes, determine acidity in homemade vinegars, test the pH of a fermented hot sauce, or simply for a science school project in class.
[Attention When Testing the pH of RO Filtered Water] When using a pH meter to test RO water, you need to know the following: All digital pH testers depend on ions in the water that pass through the probe to finally display the test results. There are not enough ions in RO water, so unstable measurement results are displayed. It is recommended to first add two drops of KCL solution (included) into the sample solution before testing the RO water to ensure accurate results.
