Precision and Accuracy Requirements

Understanding the distinction between precision and accuracy is crucial for proper scale selection. Precision refers to the repeatability of measurements, while accuracy indicates how close measurements are to the true value. Your application requirements will determine the appropriate levels for both characteristics.

Laboratory applications typically require higher precision and accuracy compared to industrial weighing tasks. Pharmaceutical research, for example, may require measurements accurate to fractions of milligrams, while shipping operations might only need accuracy to the nearest gram or even larger increments.

Consider not only your current precision requirements but also potential future needs. Investing in slightly higher precision than currently necessary can provide flexibility for evolving applications and eliminate the need for equipment upgrades in the near future.

Environmental Considerations

The operating environment significantly impacts scale performance and longevity. Temperature fluctuations, humidity levels, vibrations, and air currents all affect weighing accuracy and reliability. Ohaus scales are designed with various levels of environmental protection, and selecting appropriate specifications ensures optimal performance in your specific conditions.

Laboratory environments typically offer more controlled conditions compared to industrial settings. However, even laboratories can experience challenges from air conditioning systems, foot traffic, and nearby equipment that generates vibrations or electromagnetic interference.

Industrial environments present additional challenges including dust, moisture, temperature extremes, and mechanical vibrations. Scales intended for these applications feature enhanced protection ratings and robust construction to maintain performance under challenging conditions.

Budget and Long-term Investment

While initial cost is an important consideration, evaluating the total cost of ownership provides a more comprehensive view of your investment. This includes purchase price, installation costs, calibration requirements, maintenance expenses, and potential downtime costs if equipment fails.

Higher-quality scales typically offer better long-term value through improved reliability, longer service life, and lower maintenance requirements. Consider the cost of inaccurate measurements, including wasted materials, failed batches, and regulatory compliance issues that could result from inadequate weighing equipment.
