Center thickness measuring instrument (temperature controlled version)

The ET-3T low force electronic thickness gauge is a high-precision thickness measurement instrument suitable for contact lens or artificial lens manufacturers and related researchers. It can measure the thickness of soft contact lenses (contact lenses), soft IOLs or ICLs, and other materials that are sensitive to temperature or moisture content in a constant temperature solution. It can also measure the thickness of hard contact lenses or other materials (such as RGP, corneal reshaping lenses, or scleral lenses) in air or solution.

The ET-3T comes with a heating type constant temperature bath. By precisely controlling the temperature of the bottom plate of the constant temperature bath, the solution in the bath can be controlled in a constant temperature environment, such as simulating the human eye environment at 35 ℃. It can also be equipped with an external constant temperature circulation device to control the solution in the bath at a temperature lower than room temperature.
