VariRef the New Laboratory Refractometer

The VariRef combines proven Schmidt + Haensch technology with the modularity of the VariFamily.

The new double isolated peltier systems allows fastest temperature control and reduces the influence of environment temperature, resulting in fast and precise measurements.

The VariRef has the well-established Schmidt + Haensch sample room. Its flat shape is ideal for easy cleaning. When dealing with hard to clean or hazardous materials we offer you a special covered version to ensure a long and proper product life. The LED light source and the self-checking capabilities for cleanliness, environment temperature effects, calibration and more result in a virtually maintenance free product life.

To ensure highest precision over the long product life, the VariRef enables you to make a multi-point calibration for the complete measurement range. Thus giving you the tools for a fast and economic maintenance at your side.

With the VariRef you have access to the complete scale library of Schmidt + Haensch offering readymade solutions for numerous applications.
