Refractometers for rough conditions.
The refractometers of the Heavy Duty line are designed for measuring the refractive index under harsh environments and in special applications. To withstand rough conditions they have a hermetically sealed aluminum casing. The Abbemat 450/650 refractometers are extremely robust and waterproof (IP68). To measure samples containing solid particles or air bubbles you can position the Heavy Duty Abbemat on its side to prevent that sedimentation and disturbances affect the results. A separate control unit allows for convenient operation from a remote position.
