OHAUS EXR223 Explorer EXR Precision Balance, 220 g Capacity, 1 mg Readability, AutoCal, Touchscreen

OHAUS EXR223 Precision Balance — 1 mg Resolution Across a 220 g Working Range

Compact sample masses and tight tolerances are the daily reality in pharmaceutical R&D, chemical QC, and jewellery valuation. The OHAUS EXR223 Precision Balance addresses both with a 220 g maximum capacity and 1 mg readability, housed in a design that pairs milligram-scale precision with the everyday practicality of a touchscreen interface. The enclosed draftshield and AutoCal™ keep measurements stable without requiring constant operator attention.

Key Features

• 1 mg (0.001 g) Readability: Three-decimal precision suits precise dispensing, materials characterization, and gem/precious-metal weighing at the sub-gram level.
• 220 g Maximum Capacity: Handles the full range of routine analytical samples while remaining within the 130 × 130 mm enclosed pan chamber.
• AutoCal™ Automatic Internal Calibration: Thermal-change detection triggers the internal calibration mechanism automatically, so accuracy is maintained without manual weight handling.
• Anti-Static Glass Draftshield: Encloses the pan on all sides to block air currents; anti-static glass prevents electrostatic charge from biasing readings on lightweight samples.
• 7-inch Color Touchscreen: Full-color glass-overlay display with proximity sensors allows tare, application selection, and result review without physical key contact.
• Full Connectivity Suite: USB Device, USB Host × 2, RS232, Ethernet standard; Wi-Fi/Bluetooth optional for lab network integration.
• User Management and Audit Log: Four access tiers and 100,000-entry system log keep records organized and audit-ready for regulated environments.

Detailed Overview

The EXR223 stands out within the Explorer EXR series for the combination of its milligram resolution and medium capacity, making it useful across a wider variety of analytical tasks than either a lower-capacity semi-micro instrument or a broader-range gram-resolution balance. The 130 × 130 mm stainless-steel 316 pan provides ample room for standard containers while remaining fully enclosed by the anti-static draftshield. With NTP time synchronization active and HID driver-free PC compatibility, the balance integrates directly into documentation workflows without additional software. The 1,000-entry application sample library reduces re-entry time in repetitive parts-counting or formulation protocols. Operating reliably between 10°C and 30°C, the EXR223 is well-suited to air-conditioned laboratory environments used in analytical chemistry and QC settings.

Applications

• Precise dispensing of fine chemicals and pharmaceutical intermediates
• Precious-metal and gemstone weighing requiring milligram-level accuracy
• Check weighing of small components and packaged goods in quality control
• Parts counting in electronics manufacturing where component mass is low
