Widely used: pH test can measure in swimming pools, salt water pools, hot tubs, SPAs, aquariums, aquacultures, the pH meter can measure the EC and pH value of hydroponics. TDS and pH meters measure liquids such as permeate water, pool water, drinking water, tap water, irrigation water, pond water, garden water, coffee, fruit juice, brewed wine and beer
User-friendly design: the backlight ensures that you can use the product in dimly lit working environments. With the HOLD/TEMP button, you can record the reading, and the backlight turns off within 30 seconds. Press any button to turn on the backlight again
Calibration The unit is factory calibrated and supports automatic 3-point calibration with the included standard calibration kit (4.01 / 6.86 / 9.18 pH). In order to compensate for transport influences and ensure high measurement accuracy, it is recommended to perform the calibration according to the instruction manual at the first use
Automatic temperature compensation: the pH meter does not need to pay attention to the temperature of the test liquid; this device can accurately measure sample values within the temperature range of 0 °C - 60 °C (32 °F-140 °F), causing the problem of inaccuracy due to liquid temperature changes. Whether in winter or summer, you can get accurate values
5-in-1 pH meter: a digital water tester drinking water can measure pH, salinity, EC, TDS and temperature; simply press the (MODE/CAL) button to switch between pH, salinity, EC and TDS and read values. Long press the HOLD/TEMP button to switch between the units temperature and Celsius. Meets the requirements for regular, daily monitoring of water quality and allows you to be informed about the situation of water quality at any time

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. The GIDIGI pH meter helps you know when to add nutrient solution and when to add pH solution to adjust the pH value and ensure the healthy growth of your plants. It can monitor the pH, EC and temperature values of the hydroponic nutrient solution simultaneously on the screen without having to switch buttons.
ACCURATE PH METER WITH EFFECTIVE ATC: Our multifunctional hydroponics pH meter features automatic temperature compensation (0 to 50 C) to ensure consistent readings. The pH EC tester with TEMP function protects sensitive plants and monitors temperature changes to avoid damage and optimise growth. This is essential for hydroponic growers.
