Its 0.002g linearity specification is consistent across the full 520g span, ensuring that tared measurements at the top of the range remain as accurate as those near the pan's empty weight. The 120 mm round stainless steel pan pairs with standard 100 mL beakers and common laboratory weighing boats. Stabilization in 2 seconds keeps throughput practical for multi-sample routines. External calibration with user-selectable span points means calibration weights can be chosen to best represent the working range of each user's protocols. The balance supports 12 measurement units including pennyweight, newton, and Taiwan tael — useful in commercial and specialized research environments that employ non-standard units.\u003c\/p\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eBulk reagent preparation requiring milligram precision\u003c\/li\u003e\n  \u003cli\u003eRaw material acceptance testing in manufacturing\u003c\/li\u003e\n  \u003cli\u003eEducational laboratory weighing with larger sample sets\u003c\/li\u003e\n  \u003cli\u003eDensity determination of solid samples\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhy Choose the OHAUS PR523\/E?\u003c\/h3\u003e\n\u003cp\u003eTeams that need the precision of a milligram balance but work with samples or vessels that exceed the typical 220–320g range will find the PR523\/E the right tool.
