ThinProbe is unique as a process refractometer because it can also serve as an industrial temperature transmitter. A standard industrial temperature measurement is made by the temperature element protected by a thermowell with diameter of 1/2” (12 mm), the same diameter as ThinProbe.

The ThinProbe measures temperature as fast as a standard thin-walled Thermowell. If you already have a temperature transmitter, you can directly  replace it with  a ThinProbe refractometer adding concentration measurement.

ThinProbe is the only refractometer that reaches full concentration accuracy.
