Automatic Critical-angle Refractometer of ATR-TOUCH Series, SCHMIDT & HAENSCH

Digital refractometers for measuring the refractive index of liquid media irrespective of viscosity, color and opacity. For universal use in quality control tests in production processes and laboratories.
The new models of the well-known laboratory refractometer series "ATR" are powerful, robust units that deliver accurate, reproducible results in no time at all. In addition to a more contemporary design, the new refractometers are characterized by a very flat, easy to clean and easy to handle sample chamber and a continuous measuring mode. Nothing has been changed about the time-proven modular concept: Customers only buys what they really need for their application. This goes for the technical specifications of the refractometers as well as for the selection of hardware and software components. The measuring heads can be operated either via a PC or via the new electronic unit (L-Display). Depending on the user's requirements, different software tools are available. It is another benefit of the new electronics unit that you can use it to operate other Schmidt+Haensch devices.
