Optical pH Sensors
PyroScience optical pH sensors utilize patented REDFLASH technology that guarantees fast and accurate pH measurements with no sample consumption.
These pH sensors guarantee minimal cross-sensitivity to ionic strength and outstanding photostability that enable high sampling rates over long periods. The sensors work over a confined pH range (2 pH units) at high resolution and come in four different ranges: pH 4.0 - 6.0, 5.0 - 7.0, 6.0 - 8.0 and pH 7.0 - 9.0.
PyroScience recommends a 2-point calibration using PHCAL calibration capsules before every measurement. Please review the Optical pH Sensors User Manual for calibration tips.
Pick and choose from a variety of fiber-optic and contactless pH sensor options. Make sure to add the necessary accessories for complete system set-ups with the contactless sensors.
