Ohaus Precision Balances – High-Accuracy Laboratory Weighing from 0.001 g
Ohaus precision balances are professional laboratory weighing instruments designed for accurate, repeatable measurement in pharmaceutical, research, quality control, food production, and industrial applications. With readability from 0.001 g to 0.01 g and capacities from 200 g to 6,000 g, they deliver the precision required for sample preparation, formulation, quality assurance, and compliance testing in demanding laboratory and production environments.
Ohaus has over 100 years of weighing instrument expertise, and their precision balance range reflects this in the quality and functionality of every model. Internal calibration systems ensure the balance self-corrects for temperature drift throughout the working day without operator intervention, maintaining accuracy and reducing the burden of manual calibration routines. Touchscreen and LCD displays with intuitive menu navigation simplify operation and application mode selection, while RS-232, USB, and Ethernet connectivity enable seamless data transfer to LIMS, printers, and laboratory software for GLP/GMP-compliant record keeping. Draft shields and windbreaks protect sensitive measurements from air current interference, and stainless steel construction with easy-clean surfaces supports hygienic use in food and pharmaceutical environments.

Frequently Asked Questions
What readability do I need for my application?
For most laboratory sample preparation, formulation, and QC tasks, a readability of 0.01 g (10 mg) is sufficient. For more demanding analytical work requiring 1 mg resolution, a 0.001 g model is appropriate. For sub-milligram accuracy (0.1 mg or finer), an analytical balance is required — see our Ohaus Analytical Balances collection.
Do Ohaus precision balances have internal calibration?
Yes, many models in the Ohaus precision balance range include automatic internal calibration, which recalibrates the balance when it detects a temperature change. This ensures accuracy is maintained throughout the working day without manual calibration routines. Check individual product listings to confirm internal calibration availability on specific models.
Are Ohaus precision balances GLP and GMP compliant?
Yes. Ohaus precision balances produce GLP-compliant printed outputs including date, time, instrument ID, and weighing results. Selected models include more advanced GMP features such as user login, audit trail, and method-guided workflows. Check individual model specifications or contact our team for guidance on GMP compliance features.
Can Ohaus precision balances connect to LIMS or laboratory software?
Yes. Most models feature RS-232, USB, and Ethernet connectivity for direct data transfer to LIMS, spreadsheet software, and data logging applications. Contact us for compatibility advice specific to your laboratory software environment.
Are UKAS calibration certificates available?
Yes. UKAS-traceable calibration certificates are available on request for all Ohaus precision balances. Annual recalibration is recommended to maintain accuracy and compliance — contact our team to arrange calibration documentation or periodic service support.
