ATAGO MASTER-20M Refractometer

MASTER-20M are low concentration model (measurement range Brix 0.0 to 20.0%) of the MASTER-M / MASTER-PM. MASTER-20M are the successor model to the conventional N-20E. Good for measurements of low concentration fruit juices, cutting oil, etc. The MASTER-M / PM series is a good alternative choice when the water resistant feature is not a priority and the Temperature Compensation will be carried out manually. Not equipped with the Automatic Temperature Compensation feature.
The MASTER-20M is made of metal, and the MASTER-20PM is plastic. The specifications are exactly the same. For salty and acidic samples, choose the plastic body, MASTER-20PM.
