Ohaus PR Series Precision Balances

Ohaus PR Series precision balances provide straightforward, repeatable weighing for laboratories, education and industrial workplaces. The range covers capacities from 220 g to 6.2 kg with readabilities from 0.001 g to 0.1 g, allowing users to select fine measurement for small samples or additional capacity for larger routine loads.

Basic weighing, parts counting and percentage weighing cover core tasks such as sample preparation, component checks and material measurement. A bright backlit LCD, simple controls and adjustable environmental filters support clear operation, while the removable stainless steel pan is suited to regular use.

Every model includes an RS-232 port for connection to compatible printers or computers. PR/E models use external adjustment, PR models include InCal semi-automatic internal adjustment, and approved PR M variants are available for legal-for-trade applications. Finer-readability models include a removable glass draught shield, while larger-capacity versions use a 180 mm weighing pan.
