The OHAUS EXR224 Analytical Balance extends that range to 220 g without reducing readability below 0.1 mg — giving analytical chemists more headroom when working with denser samples or larger containers. AutoCal™ handles recalibration automatically, and the enclosed draftshield ensures the extra capacity doesn't come at the cost of measurement stability.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e220 g Capacity with 0.1 mg Readability:\u003c\/strong\u003e An extended analytical range that covers heavier samples and larger weighing vessels while maintaining four-decimal precision.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAutoCal™ Automatic Calibration:\u003c\/strong\u003e Temperature-triggered internal recalibration requires no manual interaction, making accuracy maintenance effortless during long analytical sessions.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAnti-Static Glass Draftshield:\u003c\/strong\u003e Sealed 90 × 90 mm pan enclosure prevents airflow and electrostatic interference, two factors that become critical when working at 0.1 mg sensitivity.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e7-inch TFT Touchscreen with Proximity Sensors:\u003c\/strong\u003e The full-color glass interface allows touchless taring and smooth application switching to reduce disturbance during sensitive procedures.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEthernet, USB, and RS232 Built In:\u003c\/strong\u003e Wired connectivity to PCs, printers, and LIMS is ready out of the box; optional wireless module adds Wi-Fi and Bluetooth.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDensity Determination Application:\u003c\/strong\u003e Built-in Archimedes' method density calculation for solids and liquids using the standardly included below-balance connection.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompliance Infrastructure:\u003c\/strong\u003e 100,000-entry audit log, four-tier user access, and NTP-synced timestamps ready for GLP\/GMP data integrity requirements.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eDetailed Overview\u003c\/h3\u003e\n\u003cp\u003eWhat distinguishes the EXR224 from the EXR124 is its 220 g capacity ceiling, which allows weighing of denser analytical samples — such as metal alloys, high-density powders, or larger titration vessels — without switching instruments mid-protocol. The 90 × 90 mm pan size remains consistent with standard analytical ware. The metal housing and robust glass draftshield construction maintain calibration stability during extended measurement sessions. Operating within 10°C–30°C and up to 80% relative humidity, the balance performs reliably in standard air-conditioned laboratories. HID-compatible USB connectivity eliminates driver management overhead when interfacing with Windows data-acquisition software, LIMS, or ERP systems. For organizations running multiple instruments of the same series, the shared Explorer EXR interface reduces training time across the bench.\u003c\/p\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eGravimetric analysis of denser materials exceeding 120 g sample mass\u003c\/li\u003e\n  \u003cli\u003eFormulation and compound synthesis requiring four-decimal accuracy above 120 g\u003c\/li\u003e\n  \u003cli\u003eDensity determination of high-mass solid samples using Archimedes' principle\u003c\/li\u003e\n  \u003cli\u003ePharmaceutical QC weighing where container tare weight reduces available sample range\u003c\/li\u003e\n  \u003cli\u003eCalibration verification of reference weights in the 100–200 g class\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhy Choose the OHAUS EXR224?\u003c\/h3\u003e\n\u003cp\u003eThe OHAUS EXR224 Analytical Balance provides the same four-decimal accuracy found on 120 g instruments, extended to a 220 g ceiling that handles a wider variety of laboratory samples.
