Ohaus EX225D Semi Micro Balance Analytical Scale

Ohaus EX225D Semi-Micro Analytical Balance

The Ohaus EX225D Semi-Micro Analytical Balance is engineered to deliver unmatched precision, efficiency, and reliability for advanced laboratory applications. Offering dual capacity modes—120 g with 0.01 mg readability and 220 g with 0.1 mg readability—it ensures accurate results across a wide range of weighing tasks.

Equipped with AutoCal™ automatic internal calibration, the EX225D guarantees consistent accuracy without manual intervention. A built-in ionizer neutralizes electrostatic charges, ensuring stable measurements even with fine powders and sensitive samples. The auto door system enhances workflow efficiency by allowing hands-free access, while the enclosed draftshield minimizes environmental interference.

The balance features a large 5.7-inch full-color VGA touchscreen for intuitive navigation, along with versatile connectivity options including USB, RS232, and optional Ethernet for seamless data management. Its durable stainless steel 80 mm weighing pan, in-use protective cover, and robust construction ensure long-lasting performance in high-demand laboratory environments.
