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.

Shared benefits

  • Semi-micro readability: 0.01 mg / 0.1 mg
  • Fast stabilisation, minimal waiting time
  • Large colour touchscreen with intuitive operation
  • Automatic internal calibration (AutoCal)
  • Robust, vibration-resistant construction
  • GLP/GMP data management and advanced reporting
  • Infrared touchless sensors in both series

EXR vs EXP – Differences Between Explorer Semi-Micro Balances

OHAUS Explorer EXR and EXP semi-micro balances use the same premium load cell, so their weighing accuracy and performance are identical.
The differences lie in convenience features, the level of automation and data management.
