Product information
Description
【BEFORE USE】: Place the included potassium chloride powder in 20 ml of pure water and mix well. Then, place the probe in the solution for 24 hours, remove it, and clean the residual solution from the surface of the detection bulb. You can now begin calibration. (Note: If the sponge is sufficiently wet, skip this step.) 【DURING USE】: If the calibration is inaccurate, repeat the "Before Use" step. If using your own potassium chloride powder, prepare your own solution by adding 61.5 g of KCl to 250 ml of water. Then, place the probe in the solution for 24 hours, remove it, and clean the residual solution from the surface of the detection bulb. You can now begin calibration. 【AFTER USE】: To ensure the sensitive bulb is active, add a drop of freshly prepared potassium chloride solution to the sponge inside the probe cover. Also, to better maintain the sensitive bulb's activity, add the solution to the sponge every two months. ▶【Notification】 Calibrate once a week if you frequently test a pH 10 solution, or once mid-month for neutral solutions. The 250 ml calibration solution is sufficient for multiple uses (approximately 10 ml each time). Then rinse the electrode with clean water before the next test. Rinse and allow it to stand for 3 to 5 minutes before switching from strong acid to strong alkali and vice versa. ▶【Self-Calibration】Let's make your work faster and easier than ever with this convenient pH tester! With 3-point calibration procedures, your pH tester will automatically identify calibration solutions to give you your reading every time. ▶ 【Automatic Temperature Compensation】 Temperature can affect reading levels; our pH meter's automatic temperature compensation ensures you get the best possible reading. Unlike other pH meters that only have a range of 0 to 50 degrees, ours has an even better range of 0 to 70 degrees, allowing you to 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 information in an intuitive layout so you can see even in low-visibility situations. When the pH value is below 3.5 or above 12.5, the white digital display turns red and flashes to alert you.
