Anton Paar has launched the Abbemat 450 and 650 refractometers, combining robustness with precision up to ±0.00002 nD.
The heavy duty models are designed for customers who handle aggressive samples or do refractive index measurements in fume hoods or glove boxes and can be operated remotely.
A measuring unit and a separate control unit allows the user to operate from a distance of up to 5 metres.
To achieve mechanical stability, the housing of the compact measuring unit has been manufactured from a solid block of aluminum which has been surface-anodised.
The measuring unit has been designed to withstand bumps and scrapes, as well as splashes of water. The unit is fully waterproof to a depth of one metre for up to two hours (IP68).
The Abbemat Heavy Duty is available with two different accuracy levels, according to user needs: ±0.0001 nD (Abbemat 450) and ±0.00002 nD (Abbemat 650).
The sapphire prism is scratchproof and provides a wide measurement range (1.26 nD to 1.72 nD). A built-in solid-state temperature control (Peltier) guarantees precise temperature adjustment between 10 °C and 85 °C.
