0.02mg/L,1 mg / L and 5 mg / L can be selected;
When the concentration range of the measured water is generally between 5 and 10, then 0.02mg/L,5 mg /
L and 10 mg / L can be selected;
When the concentration range of the measured water is generally between 20 and 30, then 0.02mg/L,10
mg / L and 50 mg / L can be selected;
When selecting the calibration point, please note that when the measured value is high, select a higher
value of the calibration point which is close to the measured value, and the lower point should generally
be no more than 10mg/L.
The specific calibration steps are as follows:
The following is an example of three-point calibration when measuring water below 50mg/L:
Pour the standard solution from point 1 (generally recommended 0.02 mg/L) into a clean, dry or
pre-rinsed calibration container. Carefully immerse the Sensor at the end of the main unit in the solution.
Please ensure that the front end of the Fluorine Ion Sensor is immersed in the solution at least 2 cm and
enter the standard value. After the value in the software interface is stable, click “1 point Calibration”.
Rinse and dry the sensor and calibration container with water after completion.
Pour the standard solution at point 2 (generally recommended 1 mg/L) into a clean, dry or pre-rinsed
calibration container. Carefully immerse the Sensor at the end of the main unit in the solution. Please
ensure that the front end of the Fluorine Ion Sensor is immersed in the solution at least 2 cm and enter the
standard value. When the value in the software interface is stable, click “2 point Calibration”. Rinse and
