▶ 【Notification】Calibrate once per week if you often test solution of PH 003c4 or 003e10, 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 device will 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 tha....
