OHAUS EXR1203 Explorer EXR Precision Balance, 1,200 g Capacity, 1 mg Readability, AutoCal, Touchscreen

OHAUS EXR1203 Precision Balance — 1,200 g Capacity with 1 mg Readability and AutoCal

When your laboratory demands milligram-level accuracy across a generous 1,200 g range, the OHAUS EXR1203 Precision Balance is built for the task. AutoCal™ internal calibration adjusts to changing environmental conditions automatically, while the 7-inch full-color touchscreen keeps every weighing application within reach. Eleven built-in application modes make this instrument equally valuable in R&D, QC, and teaching environments.

Key Features

• AutoCal™ Internal Calibration: Motorized weight mechanism self-calibrates whenever temperature drift is detected, maintaining traceability without manual intervention.
• 7-inch TFT Color Touchscreen: A glass-overlay display with 16.7 million colors delivers exceptional clarity, and two touchless sensors allow hands-free taring mid-procedure.
• Comprehensive Connectivity: Standard USB Device, dual USB Host ports, RS232, and Ethernet enable direct connection to PCs, printers, and LIMS; optional Wi-Fi/Bluetooth expands wireless capability.
• Anti-Static Glass Draftshield: Enclosed weighing chamber shields the 130 × 130 mm stainless-steel pan from airflow and electrostatic interference for stable, repeatable results.
• 11 Weighing Applications: Covers parts counting, check weighing, formulation, density determination, differential weighing, and more from a single instrument.
• 4-Level User Management: Configurable access tiers and an internal audit log holding 100,000 entries satisfy GLP and GMP documentation requirements.
• 1,000-Entry Sample Library: Store frequently used reference weights to accelerate parts counting and formulation workflows.

Detailed Overview

The EXR1203 sits at the heart of the Explorer EXR series, pairing a 1 mg resolution with a 1,200 g maximum load — a combination that suits mid-capacity laboratory weighing tasks where precision cannot be compromised. The metal housing provides durability in demanding settings, while the low-profile draftshield design keeps the footprint practical. NTP time synchronization ensures timestamps in your data log remain accurate for audit trails, and HID support means the balance communicates with a host computer without requiring additional drivers. For organizations running validated workflows, the structured user management system enforces accountability at every level of operation. The operating range of 10°C–30°C and 80% non-condensing humidity covers standard laboratory and quality-control environments.

Applications

• Pharmaceutical and chemical formulation requiring milligram accuracy up to 1.2 kg
• Quality control check weighing of packaged goods and sub-assemblies
• Parts counting and inventory verification in production environments
• Density determination of solids and liquids using below-balance weighing
• Academic and research laboratories requiring multi-application flexibility
