The instruments combine robustness with high precision for refractive index measurements under harsh conditions (Picture: Anton Paar)
The refractometers are suited for handling aggressive samples or for refractive index measurements in fume hoods or glove boxes. The instruments are designed for remote operation. They consist of a measuring unit and a separate control unit that can be put in a safer place. This allows the user to operate the instrument from a distance of up to 5 meters. To achieve mechanical stability, the housing of the compact measuring unit is machined from a solid block of aluminum. To enhance durability, its surface is anodized. The unit is fully waterproof to a depth of one meter for up to two hours (IP68). The refractometers are available with two different accuracy levels, according to user needs: ±0.0001 nD (Type 450) and ±0.00002 nD (Type 650). The sapphire prism is scratchproof and offers a wide measurement range (1.26 nD to 1.72 nD). Built-in solid-state temperature control (Peltier) guarantees precise temperature adjustment between 10 and 85 °C.
