Its dual-range configuration delivers 0.01 mg readability up to 120 g and shifts to 0.1 mg readability for the full 220 g range — a versatility that suits complex preparative workflows, mixed-scale compound synthesis, and quality-control verification across a wide sample-mass spectrum.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e120 g \/ 220 g Dual-Range Capacity:\u003c\/strong\u003e Upper range of 220 g at 0.1 mg broadens sample scope, while the lower range of 120 g at 0.01 mg delivers semi-micro precision when required.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAutoCal™ Automatic Calibration:\u003c\/strong\u003e Temperature-sensitive internal calibration mechanism keeps both ranges within specification without manual calibration breaks or external weights.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAnti-Static Glass Draftshield:\u003c\/strong\u003e 80 × 80 mm enclosed weighing chamber reduces electrostatic and airflow interference, essential at 0.01 mg sensitivity levels.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e7-inch TFT Color Touchscreen:\u003c\/strong\u003e Glass-overlay display with two touchless proximity sensors enables hands-free taring and mode changes to protect delicate measurements.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Wired Connectivity:\u003c\/strong\u003e USB Device, USB Host × 2, RS232, Ethernet ready out of the box; optional wireless module for network-connected data transfer.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNTP Time Synchronization:\u003c\/strong\u003e Timestamps on every logged event maintain audit-trail integrity in systems where time-of-measurement traceability is required.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e11 Weighing Application Modes:\u003c\/strong\u003e Covers formulation, differential weighing, peak hold, density determination, and more — switchable from the main touchscreen menu.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eDetailed Overview\u003c\/h3\u003e\n\u003cp\u003eThe EXR225D differs from the single-range EXR225 in that it extends the upper capacity to 220 g while maintaining the 0.01 mg floor at 120 g, creating a wider practical window for compound development workflows. Analysts preparing multi-step reactions — measuring a 150 g solvent base at 0.1 mg followed by a 50 mg active ingredient at 0.01 mg — can remain on a single instrument. The 80 × 80 mm pan and fully enclosed anti-static draftshield keep both ranges protected from environmental disturbance. Metal housing ensures dimensional stability, and the 10°C–30°C operating window corresponds to standard climate-controlled laboratory settings. The HID-compatible USB connection removes device-driver overhead when connecting to host PCs, simplifying IT management in multi-instrument labs. A 1,000-entry sample library reduces repetitive data entry across high-throughput weighing schedules.\u003c\/p\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eMulti-step pharmaceutical synthesis mixing micro-quantity additives with larger solvent or excipient masses\u003c\/li\u003e\n  \u003cli\u003eQC comparison testing that spans semi-micro and standard analytical sample sizes in the same batch\u003c\/li\u003e\n  \u003cli\u003eMaterials science research with wide sample-mass variation across experimental conditions\u003c\/li\u003e\n  \u003cli\u003eCalibration-laboratory verification of weights across the 100–200 g class at two precision levels\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhy Choose the OHAUS EXR225D?\u003c\/h3\u003e\n\u003cp\u003eThe OHAUS EXR225D Semi-Micro Balance removes the need to maintain two separate high-precision instruments for overlapping mass ranges.
