Digital pH Meter- Backlight PH Meter 0.01 High Precision Water Quality Tester PH Range is 0-14- for Household Drinking- Pool and Aquarium -Blue-

?Automatic temperature compensation? ?No need to take care about the temperature of testing liquid, as ph meter has built in (ATC) automatic temperature compensation, so that it can accurately determine pH value of the sample at any temperature in a range of 0? - 50?(32? - 122?). ?LCD Display? ?Digital PH meter can measure & display pH result simultaneously with LCD display, which is reliable and quick reading. Easy to use even the first time use. ?Calibration? 1. Turn on the pH meter 2. Dissolve each buffer solution in 250 ml of distilled water 3. Immerse the electrode into the pH 6.86 solution.(under the temperature of 25?) 4. Press the “CAL”(calibration) button for 5 seconds and release - Display screen will start flashing “6.86” - Wait it until the display screen stops flashing. - Rinse the electrode with distilled water and make it dry. 5. Repeat the above steps with 4.01 pH buffer powder and 9.18 pH buffer powder. ?Please Note? ?Be sure to add water according to the required ratio, otherwise it will affect the accuracy of the calibration and increase the error ?Calibration powder: pH standard solid substance. It can be used after adding water. Suitable for the calibration of any type of ph meter. Each package can prepare 250ML standard solution. ? Clean the electrode with distilled water Every time before and after use ? Remember to gently wipe it with a clean, soft cloth when you're done before capping it again. ?Package Includes? ? 1 x PH Meter ? 1 x Carrying case ? 1 x User's manual
