The Sendot optical pH sensor is a highly versatile device based on a ratiometric optical measurement.
The operational pH range is from 3.0 to 8.5.
The design makes the sensor highly insensitive to drift.
Because the indicator dye is in equilibrium with the pH in the aqueous medium, the sensor needs little
to no calibration.
There is little to no influence of ion-strength and temperature.
Therefore applications in low conductivity solutions are available.
The sensor is ideal for laboratory and environmental applications.
