【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.

▶ 【Notification】Calibrate once per week if you often test solution of PH <4 or >10, or once per half month for neutral solutions. The 250ml calibration solution for multiple uses (10ml or so each time). Then rinse the electrode with pure water before next test. Rinse and rest 3-5 min before conversing from strong acid to strong alkaline and vice versa.

▶ 【Automatic Calibration】 We make your job faster and easier than ever with this convenient PH tester! With the 3-point calibration procedures, your PH testing devicewill automatically identify the calibration solutions to give you your reading in a snap.

▶ 【Automatic Temperature Compensation】 Temperature can affect reading levels, our PH meter's automatic temperature compensation can ensure that you're getting the best possible reading. Unlike other PH metersthat only have a range of 0-50 degree, ours has a even better range of 0-70 degree, so you can test with confidence in any environment.

▶ 【Clear Digital Display with Alerts】 Tired of squinting at a small screen to get your readings? Enjoy this PH meter's large, backlit LCD screen that displays the information in an intuitive layout so you can still see even in low visibility situations. When the PH value is lower than 3.5 or higher than 12.5, the white digital display will change to red and flash to alert you.

▶ 【User Friendly】 You can easily replace the 2 AAA batteries when it's time, and you can also activate the 15-minute auto-off functionality to save battery. Plus, it even comes with a storage case to keep it safe and protected when you're on the go.
