The combination of AutoCal and the included draftshield addresses the two most common sources of measurement error at the milligram level—temperature drift and air currents—without demanding constant attention from the operator. Stainless steel pan construction withstands chemical exposure and daily cleaning, while the full-color VGA touchscreen supports 15-plus applications including density determination, differential weighing, SQC statistics, and pipette adjustment. The balance's compact housing (393 × 350 × 230 mm with the draftshield) fits standard lab bench configurations, and the operating temperature range of 10–30 °C covers typical climate-controlled workspaces. With typical repeatability matching the stated 0.001 g readability, results remain consistent across multiple operators and work sessions.\u003c\/p\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003ePharmaceutical compounding, raw-material verification, and dosage preparation\u003c\/li\u003e\n  \u003cli\u003eGemological and precious-metal weighing in certified carat measurements\u003c\/li\u003e\n  \u003cli\u003ePipette adjustment and calibration verification in analytical labs\u003c\/li\u003e\n  \u003cli\u003eDensity determination using OHAUS's integrated calculation routine\u003c\/li\u003e\n  \u003cli\u003eEducational and research weighing requiring traceable milligram data\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhy Choose the OHAUS EX223N?\u003c\/h3\u003e\n\u003cp\u003eAnalytical chemists, quality assurance technicians, and gemologists who demand reliable milligram-level accuracy will appreciate how the OHAUS EX223N Precision Balance combines automatic recalibration with draftshield protection in a compact, legally certified instrument.
