Optical pH Sensors

All PyroScience optical pH sensors utilize patented REDFLASH technology that guarantees fast and accurate pH measurements with no sample consumption. 


PyroScience pH sensors guarantee minimal cross-sensitivity to ionic strength, and outstanding photostability of new sensors enable high sampling rates over long periods. The sensors work over a confined pH range (2 pH units) at high resolution. We offer sensors for two different ranges: pH 6.0 - 8.0 and pH 7.0 - 9.0.


Pick and choose from a variety of fiber-optic and contactless pH sensor options. 

Fiber Optic pH Probes
