MASTER-4M / MASTER-4PM has a measuring range between the MASTER-2M / 2PM and the MASTER-3M / 3PM (measurement range Brix 45.0 to 82.0%).

Not equipped with the Automatic Temperature Compensation feature.
The MASTER-4M is made of metal, and the MASTER-4PM is plastic. The specifications are exactly the same. For salty and acidic samples, choose the plastic body, MASTER-4PM.
