Three different modes: Switch between output of results in TDS (ppm) or EC (μs) at the touch of a button. In addition, the device is able to indicate the temperature of the measured liquid in Celsius or Fahrenheit.
Ready for immediate use: Our conductor meter is already pre-calibrated from the factory. After switching it on, you can start measuring immediately. Post-calibration is possible at any time via the screw on the back of the device.
Quick measurement of solvent materials: The gauge is able to measure the electrical conductivity of the water (EC). From this value, the number of solids TDS (Total Dissolved Solids) can also be determined.
Perfect readability guaranteed: Thanks to the practical hold function, measuring results can be frozen for easy reading. The brightly illuminated display makes it much easier to operate the conductivity meter especially in the dark or under strong light incidence.
Accurate measurements: The MEASURY TDS&EC meter measures the conductivity (EC) of 0 - 9,990 μs/cm and the TDS value of 0 - 9,990 ppm. Resolution: 1μs/ppm from 0 - 999, 10 μs/ppm from 1,000 - 9,990. The accuracy of the measuring device is ± 2 %.

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.
