PH Sensor Test Pen

PH Sensor Test Pen has a sensitive electrode sensor that reads pH levels with high accuracy. This PH meter is useful for those who need a PH tester for household use. This PH sensor test pen is can be used wide range of uses and is portable, fast and accurate.

Specification:

• Measure range : 0.00-14.00 pH
• Resolution : 0.01 pH
• Accuracy : +/- 0.01 pH
• Power supply : 2*1.5V (LR44 Button cell)
• Operating temperatures : 0-60℃
• Calibration : three points automatic calibration (only 6.86 points calibration : the accuracy is 0.1 pH)
• Dimension : 15.3 * 3.1 * 1.5 cm
• Materials : Plastic + Glass Bulb Electrode

How to Use :

Operation :

1. Remove the protective cap and protective film on the screen
2. First rinse the electrode with distilled water,and dry it with filter paper
3. Turn the meter on by pressing the “ON/OFF”key
4. Immerse the pH meter electrode in the solution to be tested(can not be over the immersion line)
5. Stir gently and wait around 30s till the reading stabilized
6. After finished,clear the electrode with the pure water,turn the meter off by pressing “ON/OFF”key
7. Always replace the protective cap after use

Calibration :

1. Turn open pH meter,disolve each buffer solution in 250ML of distilled water
2. Immerse the electrode in pH 6.86 standard buffer solution(under the temperature of 25)
3. Press the “CAL” button. Wait until the display digital is 6.86pH and steady
4. Clean the electrode in distill water and dry it, immerse the electrode in Ph 4.00 standard buffer solution
5. Press the “CAL” button. Wait until the display start flashing is 4.00pH. Then complete pH 4.00 calibration
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 Tester
• 2 x Buffer Powder
