VariRef
Refractometer

The new laboratory refractometer from Schmidt+Haensch.

The VariRef’s modular design allows you to integrate all your VariFamily instruments on one platform.

The new double isolated Peltier system and precision thermometer allow fast, precise temperature control while reducing the influence of ambient temperature.

The VariRef sample room has a flat design making it ideal for easy cleaning. A special covered version is available for use when dealing with hard to clean or hazardous materials.

The self-checking capabilities for cleanliness, ambient temperature effects, and calibration make the VariRef a virtually maintenance-free instrument.

Included is access to the complete Schmidt + Haensch scale library offering readymade solutions for numerous applications.
