Ohaus Balance Scale Value Guide

This mid-century Ohaus double-beam balance scale represents the pinnacle of American mechanical precision from the 1940s to 1960s. Originally manufactured in Newark, New Jersey, these cast iron and steel instruments were essential for accurate measurements in laboratories and pharmacies before the digital era.

What Is Ohaus Balance Scale Worth?

The typical price range for Ohaus Balance Scale is $75 - $100 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• Condition of the light blue enamel pan, as significant chipping or heavy oxidation reduces the item's display value.
• Presence and smooth movement of the original sliding weights along both measurement beams.
• Mechanical functionality and the ability of the scale to achieve a perfect balance at the zero mark.
• Overall aesthetic preservation of the cast iron body, including the original paint and lack of structural cracks.

How to Identify Ohaus Balance Scale?

• Look for the 'Ohaus' brand name embossed or printed clearly on the cast iron base or the beam assembly.
• Identify the signature light blue enamel finish on the weighing pan, which is characteristic of mid-century Ohaus models.
• Verify the double-beam mechanism featuring sliding poise weights and a central pointer for zeroing the scale.
• Check for 'Made in U.S.A.' markings often located on the frame or the underside of the base.

History of Ohaus Balance Scale

Ohaus Corporation has a rich history dating back to 1907 when Karl Ohaus, a German immigrant, founded the company in Newark, New Jersey. Initially, the company manufactured precision scales for laboratory and industrial use, quickly gaining a reputation for accuracy and durability. The double-beam balance scale, like the one pictured, was a staple in scientific and pharmaceutical settings for decades, prized for its ability to provide highly precise mass measurements without requiring electricity. These mechanical scales played a crucial role in scientific discovery and quality control before the widespread adoption of electronic scales.
