Ohaus Portable Balances – Accurate Weighing in the Field, Lab & Classroom
Ohaus portable balances are compact, battery-powered weighing instruments designed for accurate measurement wherever a fixed mains-powered balance is impractical or unavailable. Combining the precision and reliability of Ohaus’s 100+ years of weighing expertise with lightweight, rugged construction and rechargeable or battery operation, they are the practical choice for field sampling, site quality control, educational laboratories, outdoor markets, and any application requiring accurate weighing away from a fixed workstation.
Despite their compact size, Ohaus portable balances deliver the accuracy and functionality expected from professional laboratory instruments. Readability options from 0.01 g to 1 g cover a wide range of applications from precise field sampling through to general-purpose portable weighing. Multiple weighing units, tare functions, and application modes including parts counting, percentage weighing, and checkweighing are available on many models, making them versatile instruments for diverse portable weighing tasks. Backlit displays ensure clear readouts in outdoor and low-light conditions, and protective carrying cases are available for safe transport between locations.

Frequently Asked Questions
How accurate are Ohaus portable balances?
Ohaus portable balances are available with readability from 0.01 g (for precise field and laboratory applications) to 1 g (for general-purpose portable weighing). Accuracy is comparable to equivalent bench-top models under stable conditions. For best results, use on a flat, stable surface away from wind and vibration, and allow the balance to stabilise before taking readings.
How long does the battery last on Ohaus portable balances?
Battery life varies by model and usage, but most Ohaus portable balances provide several hours of continuous use on a set of batteries or a full charge. Auto power-off functions help conserve battery life during periods of inactivity. Check individual product specifications for battery life data.
Can Ohaus portable balances be used outdoors?
Yes. Ohaus portable balances are designed for field and outdoor use, with backlit displays for visibility in varying light conditions. For best accuracy outdoors, use on a stable, level surface and shield the balance from wind, which can affect readings at higher resolutions. Some models include a windshield or draft shield for improved outdoor performance.
