OHAUS PR224/E PR Analytical Balance, 220g Capacity, 0.1mg Readability, RS232 Connectivity

OHAUS PR224/E PR Analytical Balance — Dependable 0.1 mg Analytical Performance with RS232

When accuracy requirements reach 0.1 mg but budget constraints are real, the OHAUS PR224/E PR Analytical Balance fills the gap effectively. Offering 220 g capacity with four-decimal resolution, a glass draftshield, and RS232 connectivity, it provides essential analytical functionality for laboratories that prioritize measurement accuracy over advanced software features.

Key Features

• 0.1 mg Readability Across 220 g: Four-decimal precision across a 220 g range supports weighing tasks that require analytical accuracy without the smaller capacity typical of high-end analytical models.
• Glass Draftshield Enclosure: Air current interference is a primary source of error at the 0.1 mg level; the enclosed draftshield creates a sheltered measurement environment that eliminates this variability.
• RS232 Serial Output: Direct connection to computers, printers, or data-logging terminals enables straightforward record keeping without the added complexity of USB host functionality.
• Backlit LCD with Simple Navigation: A clear, illuminated readout and minimal menu structure keep the learning curve low for occasional users or shared-instrument environments.
• 3-Second Stabilization, 200 mg USP Minimum Weight: These figures confirm analytical-grade performance suitable for pharmaceutical method development and validation where USP specifications apply.
• Stainless-Steel Pan, 90 mm Diameter: The pan matches the diameter required for standard analytical weighing vessels and is removable for straightforward cleaning and maintenance.
• External Calibration Ready: Designed to accept certified external weights, making it suitable for ISO 17025-accredited labs or facilities with established external calibration programs.

Detailed Overview

The OHAUS PR224/E achieves ±0.0002 g linearity and 0.0001 g typical repeatability — performance metrics that put it firmly in the analytical tier. The 3-second stabilization time is consistent with draftshield-equipped analytical balances at this resolution. Its compact footprint (317 mm × 303 mm × 201 mm) fits standard analytical bench positions, and the draftshield housing protects the pan from contamination between measurements. Ten weighing units including milligrams, carats, grains, and Troy ounces cover the most common analytical and trade applications. The absence of complex compliance management features keeps the instrument affordable while preserving the accuracy that analytical work demands.

Applications

• Pharmaceutical reagent and API weighing in research and QC labs
• Analytical sample preparation for chromatographic method development
• Reference standard preparation and purity verification
• Educational demonstrations of analytical weighing techniques
