Ohaus Triple Beam Balance

The Ohaus Triple Beam Balance is a quintessential laboratory instrument known for its precision, durability, and mechanical reliability. Invented by Gustav and Karl Ohaus in 1907, the brand became the standard for weighing in scientific and educational environments across the globe. This specific vintage model showcases the classic black cast-iron base and mechanical sliding poises that have made Ohaus a household name in physics and chemistry labs for over a century.

Throughout its history, Ohaus has maintained a reputation for high-quality engineering. While modern versions of their products are manufactured globally, the heritage models like the one pictured were primarily manufactured in the United States. In 1997, Ohaus was acquired by Mettler Toledo, a global leader in precision instruments. This acquisition combined Ohaus's market-leading position in education and basic weighing with Mettler Toledo's extensive technological resources, ensuring the brand remains a dominant force in the 2026 market and beyond.
