Ohaus PR224 PR Series Analytical Balance, 220 g x 0.0001 g, Internal Cal

The Ohaus PR224 is designed for high-precision laboratory weighing where extremely accurate measurements are required. With a 220 g capacity and 0.1 mg readability, it is commonly used for chemical analysis, pharmaceutical compounding, sample preparation, formulation, density-related testing, quality control, and research applications that require repeatable results at very small measurement increments.

Yes. The Ohaus PR224 features semi-automatic InCal™ internal calibration, which helps users quickly verify and maintain weighing accuracy without always requiring external calibration weights. This feature is especially useful in laboratory environments where temperature shifts or frequent use may affect measurement consistency over time.

The Ohaus PR224 includes a removable glass draft shield to help protect highly sensitive measurements from airflow and environmental interference. Since analytical balances measure extremely small weight changes, even minor air movement or vibration can affect readings, making the draft shield important for stability, repeatability, and dependable weighing performance.

Yes. The PR224 includes an RS-232 communication port for transferring weighing data to compatible printers, computers, or laboratory management systems. This feature helps simplify documentation, traceability, reporting, and quality assurance processes in research and regulated laboratory settings.

The Ohaus PR224 supports multiple weighing modes including basic weighing, percent weighing, and parts counting. These built-in functions make the balance versatile for routine analytical workflows, formulation tasks, comparison testing, and repetitive laboratory measurements that require both speed and precision.
