Calibration with standard buffers:

1. Pour appropriate amount of standard buffer solution 6.86, 4.01 (temperature: 25C) into separate clean beakers.

2. For accurate calibration, separate two beakers for each buffer solution, one for rinses the electrode and one for calibration to minimize contamination with standard buffer solutions.

3. Tap ON/OFF to switch ON the power.

4. Put the instrument into the standard buffer, and gently shake until the value is stable, press CAL key, the instrument will enter the automatic calibration state,The value is flashing until the flashing stops and the calibration is completed.

 

Using pure water (PH value is 7) correction:

1. In order to calibrate accurately, two beakers should be divided into two parts. One beaker is used to rinse the electrode and the other beaker is used to calibrate to reduce pollution.

2. Tap "ON/OFF" to switch ON the power.

3, calibration, need to put the instrument in pure water, press - button, display 6.86 flashing, the instrument into automatic calibration state, the value will be flashing until flashing stop positive, the display value is 6.86. Complete calibration.

 

Note: The recommended calibration water temperature is 25 degrees Celsius

 

Calibration liquid shall be distilled or purified water (PH 7)

 

Tap water cannot be used, because tap water quality is complex and its PH is unstable, which cannot ensure the correctness of calibration

 

Note: 1. The electrode should be cleaned after use 2. PH calibration: 1 point or 2 points or 3 points automatically. If the meter cannot recognize the solution, please replace the electrode or contact the supplier. 3. It has been factory calibrated and can be used directly. 4. After completion, clean the electrode with pure water and keep it dry. 5. Stir gently a few times to ensure that there are no bubbles around the electrode. 6. Do not disassemble the meter without permission. Troubleshooting: Ph reset 1. Turn off the meter, press HOLD/TEMP and MODE/CAL at the same time, don't release it. 2.Press ON/OFF, then release all buttons, the reset is complete.

 

 Q: Is it necessary to calibrate the function of the instrument to measure "hydrogen"?

 A: The product has been calibrated before leaving the factory. The product cannot calibrate the function of the instrument to measure "hydrogen" by itself.cup after electrolysis, and then measure. The hydrogen content is relatively small, and the measurement data will also display "0". Hydrogen is very easy to volatilize, and the value will continue to decrease over time.

 

Q: What is the unit for measuring hydrogen? How to convert measurement units?

 A: The factory default measurement unit of the instrument is ppb. When the instrument is turned on, press the FUN" key, and the measurement mode will be switched between ppb and ppm. (1ppm =1000ppb) Q: What should I do if the received product is damaged, cannot be calibrated, ca
