The Best Ph Meter For Hydroponics in 2023

【High Accuracy & More Sensitive Bulb Design PH Meter】: The core of the ph tester digital is the electrode, and the core of the ph tester electrode is the bulb. The ppm meter bulb made by blue effect technology is blown at a high temperature of 1000 degrees Celsius. This can fully respond to the H+ ions in the solution.The bulb glass film uses a low-impedance glass sensitive film (≤25MQ), and the reaction speed of the TDS PH meter is also greatly improved, reaching a true level of 0.01 !

【PPM Meter with One Key Lock Value Function 】: When the measured value is stable, just press the HOLD/TEMP key to lock the measured value and take it out for viewing, which is really simple. (Before press "HOLD/TEMP" key, the number of pH is fluctuate slightly which is normal.)

【Easy to Use Lab PH Meters with Backlit LCD Design 】: Just remove the ph pen protective cap and immerse the ph water tester electrode in the solution and press the button to be measured. Don't worry about seeing the displayed value when there is insufficient light. Water ph tester features a green backlit LCD to help you see the measurement clearly in any situation.

【TDS Meter with Automatic Temperature Compensation】: Temperature can affect reading levels, our water meterr's automatic temperature compensation can ensure that you're getting the best possible reading. Unlike other ph meter for water hydroponics that only have a range of 0 °C-50 °C, ours ph meter for water hydroponics has a even better range of 0 °C-60 °C (32 °F-140 °F) , so you can test with confidence in any environment.

【PH Tester with Wide Application】: Ideal for household and laboratory pH testing applications, including drinking water, swimming pool, pond, beer brewing, kombucha, aquariums, hydroponics, laboratory, food processing etc. (Range: 0.01 - 14.00pH; Resolution: 0.01pH; Accuracy:±0.05pH; TDS range: 1-9990ppm; Resolution:1ppm; 0.1ppt; Accuracy: ±2% F.S. ), reliable and quick readings.

【How to use calibration】Press CAL for 5 seconds to enter the calibration mode, press in turn to select the powders corresponding to 6.86, 4, and 9.18 to complete the calibration.

【Mini Size】The mini size ph meter we designed allows you to easily put it in your pocket, so you can take measurements anytime, anywhere. It can help you test it whether you take it to the pool, on a trip, to the beach or camping.

【Family Essentials】As a tool to improve the quality of life. Can be used to test drinking water, swimming pools, PH balance in aquarium, RO system, spa or hydroponics. Basically all the environments that need to test PH value can use this tester to get accurate data.

【Easy to use】turn on the switch,put the probe into the water and stir (make the small glass ball fully contact the liquid) and the value can be read when the value is stable.

【Automatic temperature compensation】There is no need to care about the temperature of the liquid being measured. The PH meter has an automatic temperature compensation function, which can be adjusted according to the water temperature and water quality.
