Compact Portable Design: Pocket-fitting pH meter that's lightweight and compact. Can be concealed in your bag or pocket for easy carrying. Ⅶ. Specification: Ⅷ. Display: LCD Digital Ⅸ. Accuracy: 0.01 Ⅹ. Resolution: 0.01 Ⅺ. Operating Temperature: 0~60°C Ⅻ. Measuring Range: 0.00~14.00 ⅩⅢ. Probe Type: Precision glass bulb electrode ⅩⅣ. Power Supply: 2*1.5V LR44 Batteries (Not included) ⅩⅤ. Illustrate: ⅩⅥ. Step 1. Remove protective cap. ⅩⅦ. Step 2. First rinse the electrode with distilled water and suck it with filter paper. ⅩⅧ. Step 3. Turn the meter on by pressing ON/OFF key. ⅩⅨ. Step 4. Immerse the pH meter electrode in the solution to be tested (should not be over the immersion line). ⅩⅩ. Step 5. Stir gently and wait around 30 seconds till the reading stabilizes. ⅩⅪ. Step 6. After finishing, clear the electrode with pure water, turn the meter off by pressing ON/OFF key. ⅩⅫ. Step 7. Always replace the protective cap after use. ⅩⅩⅢ. Instructions: ⅩⅩⅣ. 1. Turn on pH meter. ⅩⅩⅤ. 2. Dissolve each buffer solution in 250ML of distilled water. ⅩⅩⅥ. 3. Immerse the electrode into the pH 6.86 solution (under the temperature of 25°C). ⅩⅩⅦ. 4. Press the CAL (calibration) button for 5 seconds and release. Display will start flashing 6.86. Wait until the display stops flashing. Rinse the electrode with distilled water and dry it with filter paper. ⅩⅩⅧ. 5. Immerse the electrode in pH 4.00 solution. Press "CAL" button for 5 seconds, then press and release immediately a second time. Reading will start flashing 4.00. Wait until display stops flashing. Rinse and dry the electrode with distilled water as before. ⅩⅩⅨ. 6. Place the meter back into the buffer solution to test calibration. If incorrect, please repeat the calibration. ⅩⅩⅩ. 7. If the approximate pH of your test solution is known to be above 7.0, calibrate the meter using 6.86 and 9.18 solution. To do this, please follow the calibration chart. The third step is the calibration method for 9.18 point. ⅩⅩⅪ. Package includes: ⅩⅩⅫ. pH detection pen*1 ⅩⅩⅩⅢ. Note: ⅩⅩⅩⅣ. 1. Due to different monitor and light effects, the actual color of the item might be slightly different from the color shown in the pictures. ⅩⅩⅩⅤ. 2. Please allow 1 cm/0.39"-3 cm/1.18" measuring deviation due to manual measurement.
