Specifications: Measuring range: 0.00-14.00 pH Resolution: 0.01 pH Accuracy: 0.01 pH Batteries: 2X 1.5V LR44 (included) Automatic temperature: 0-60℃(32-122℉) Dimensions: 15x2.5x1.3cm/6x1.1x0.5 inch Probe Type: Precision glass bulb electrode Net Weight: 52g/1.83 oz Calibration: STEP 1: Turn open pH meter,disolve each buffer solution in 250ML of distilled water STEP 2: Immerse the electrode in pH 6.86 standard buffer solution,(under the temperature of 25) STEP 3: Press the "CAL" button. Wait until the display digital is 6.86pH and steady STEP 4: Clean the electrode in distill water and dry it, immerse the electrode in Ph 4.00 standard buffer solution STEP 5: Press the "CAL" button. Wait until the display start flashing is 4.00pH. Then complete pH 4.00 calibration STEP 6: Clean electrode and dry it, put the meter into PH 9.18 standard buffer solution. Check if reading is correct between 9.17-9.19pH Package Includes: 1 x PH Meter 2 x Calibration packets 1 x Plastic case 1 x User's manual Kindly Reminder: If the tester was used or lay aside long time: recalibrate it . If you open battery case or replace battery: recalibrate it. Remember to gently wipe it with a clean, soft cloth when you are done before capping it again.

Dead in just one day use
This PH meter works fine, reading was accurate, but after about 2 hours calibration and using, it seems having water inside, all reading becomes 0.000. I kept it in a dry place, after 3 days, the water inside looks clean, but the reading is still the same 0.000.
