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. 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.
