    VariRef² – Laboratory Refractometer

    SCHMIDT + HAENSCH VariRef² is a state-of-the-art laboratory refractometer designed for precise determination of the refractive index (RI) and Brix values across a wide measurement range.

    Thanks to advanced Peltier temperature control, multi-point calibration, and a modular design, the VariRef² enables fast, precise, and reliable measurements of various liquid and solid samples. The adaptable measuring chamber allows for easy cleaning and adjustment to different sample types.

    The instrument can be connected to a computer, tablet, or smartphone via a network, while Aquisys3 software enables easy operation and data processing. An optional Pharma module with 21 CFR Part 11 compliance is also available, making the instrument suitable for pharmaceutical applications.
