Ohaus Explorer (EXP and EXR) Semi-Micro Balances
Semi-Micro Balances – High-End Laboratory Precision
The OHAUS Explorer semi-micro balances (EXR and EXP series) are OHAUS's most precise and advanced semi-micro balances, designed for critical laboratory measurements.
With a readability of 0.01 mg, exceptionally fast stabilisation and excellent repeatability, these models clearly belong in the high-end category.
Explorer semi-micro balances are ideal for pharmaceutical, biotechnology, research and quality control laboratories where accuracy, traceable documentation and standards compliance are essential.
EXR and EXP – Two Tiers of Explorer Semi-Micro Balances
- EXR models offer premium weighing accuracy in a streamlined, more cost-effective design, while the EXP series provides full automation, touchless control and advanced data management.
- EXP semi-micro balances are specifically designed for standards-driven, audited laboratories where user access management, an audit trail and 21 CFR Part 11 support are required.
