OHAUS EXR125D Explorer EXR Semi-Micro Balance, 82 g/120 g Capacity, 0.01 mg/0.1 mg Readability, AutoCal, Touchscreen

OHAUS EXR125D Semi-Micro Balance — Dual-Range Flexibility at 0.01 mg and 0.1 mg

Not every weighing task calls for the same resolution, and the OHAUS EXR125D Semi-Micro Balance is built around that reality. Its dual-range design delivers 0.01 mg readability within an 82 g capacity, then switches to 0.1 mg readability for the full 120 g range — giving a single instrument the versatility to handle both ultra-precise micro-weighing and routine analytical tasks without compromise. AutoCal™ keeps both ranges calibrated automatically.

Key Features

• Dual-Range Operation: Toggles between 0.01 mg readability (82 g max) and 0.1 mg readability (120 g max), covering micro-scale and standard analytical tasks from one platform.
• AutoCal™ Automatic Calibration: Internal calibration weight activates when temperature drift is detected, keeping both measurement ranges accurate without scheduled manual calibration.
• Anti-Static Glass Draftshield: The enclosed 80 × 80 mm chamber suppresses electrostatic and airflow disturbances that would otherwise limit accuracy at the microgram level.
• 7-inch TFT Touchscreen with Touchless Control: Glass-overlay display and proximity sensors enable hands-free operation, protecting delicate samples from physical contact and vibration.
• Comprehensive Data Output Ports: USB Device, two USB Host ports, RS232, and Ethernet are standard; optional wireless module enables network-based data transfer.
• 11 Weighing Applications: Includes formulation, density determination, differential weighing, dynamic weighing, and peak hold — accessible directly from the touchscreen.
• Audit-Ready Logging: A 100,000-entry system log combined with four-level user access control simplifies GLP and GMP compliance audits.

Detailed Overview

The EXR125D addresses a common laboratory challenge: needing both semi-micro precision and a broader analytical range without purchasing two separate instruments. At its fine range, the 82 g / 0.01 mg specification covers micro-formulation and trace weighing applications that demand near-absolute accuracy. At the coarser range, the 120 g / 0.1 mg setting handles standard four-decimal analytical work. The 80 × 80 mm stainless-steel pan accommodates both weigh-boat sizes. Metal housing, robust draftshield construction, and a stable operating window of 10°C–30°C make this balance suitable for demanding laboratory settings. NTP time sync and driver-free HID connectivity to host computers complete a specification that integrates smoothly with modern data management systems.

Applications

• Pharmaceutical micro-dosing workflows that span microgram to sub-gram sample masses
• Research chemistry requiring flexible switching between semi-micro and analytical precision
• Trace impurity analysis where sample size determines required resolution
• Calibration and metrology laboratories verifying small weights at two precision levels
