● Measurement is possible by simply drawing in sample water from existing filtration equipment, etc.
● Equipped with a sensor holder and stirrer that are convenient for calibration (easy to calibrate with standard solution)
● Fluoride ion measurement can be added up to 2 locations by adding a fluoride ion measurement unit.
● Continuous measurement and measurement value storage function by SD card (built-in data logger function)

● Measurement of “fluoride ion concentration” contained in factory effluent
● Plating / stainless steel pickling factory (using hydrofluoric acid / mixed acid)
● For monitoring the final effluent (within the standard)

Fluorine is used in various applications such as cleaning processes for semiconductor manufacturing and glass melting accelerators, but it does not biodegrade due to its high stability, and there is concern about toxicity to the human body, so strict emission standards are national. It is more defined.

＜Fluoride ion (F-) measurement method (fluoride lantern electrode method)＞
This is a measurement method used in JIS, etc., which uses a fluorine ion electrode that uses a lanthanum fluoride solid film that responds to fluorine ions.

＜Interfering substance＞
OH-Al3 + Si4 + Ca2 + HF (hydrofluoric acid) does not interfere (cannot be measured)
