Current pH sensors do not fully meet requirements for reliable and continuous remote control of industrial processes. They require high maintenance costs, are fragile and need frequent manual calibrations to maintain their accuracy (highly dependent on human error, buffer solution quality, etc.).
Therefore, this calibration free pHmeter ensures increased reliability and accuracy while being user friendly.
The innovation is a pH sensor without calibration which consists of an optical fiber (diameter 200 µm) comprising pH sensitive fluorescent molecules. The latter are excited via the optical fiber and emit a fluorescence spectrum. This spectrum is converted into a pH value via a dedicated mathematical physico-chemical model.
This model eliminates the need for calibration which brings reliability and precision to pH measurement.
