OHAUS PR224 PR Series Analytical Balance, 220g Capacity, 0.1mg Readability, Internal Calibration

OHAUS PR224 PR Series Analytical Balance — Expanded 220 g Range at 0.1 mg Resolution with InCal

When analytical work routinely involves samples close to or above 120 g, the OHAUS PR224 Analytical Balance answers with a doubled capacity ceiling — 220 g — while maintaining the same 0.1 mg readability, semi-automatic InCal calibration, and RS232 connectivity that define the PR series value proposition. It fills the gap between entry-level analytical instruments and higher-cost touchscreen platforms.

Key Features

• 220 g Capacity with 0.1 mg Readability: A broader working range accommodates heavier containers, multi-component samples, and larger individual specimens without sacrificing analytical resolution.
• InCal Semi-Automatic Internal Calibration: Initiating calibration is a single-user step without the need for external standard weights, keeping the process quick and cost-effective.
• Glass Draftshield with Sliding Top Door: Minimizes air current interference during fine weighing operations while the sliding door maintains efficient sample access.
• RS232 Communication Port: Direct serial output facilitates data transfer to laboratory printers, computers, and LIMS for documentation and GLP compliance.
• User-Selectable Environmental Filters: Adjustable response filters compensate for vibration and air disturbances in less-than-ideal lab environments, preserving reading stability.
• Software Lock and Reset Menu: Protects method settings from unauthorized changes — valuable in multi-user or regulated environments where configuration consistency is critical.
• Integrated Weigh-Below Hook: Enables density determination of solids and liquids using Archimedes' principle without additional hardware.

Detailed Overview

The PR224's 220 g capacity makes a tangible difference when weighing larger containers such as 250 mL beakers, multi-ingredient blends, or bulkier biological specimens. Typical repeatability of 0.0001 g and ±0.0002 g linearity ensure that measurements remain reliable across the extended range. User-definable project and user IDs link each measurement to a specific analyst or experiment, supporting traceable record-keeping in accredited facilities. Auto-tare simplifies sequential weighing, and auto-dim reduces screen wear during idle periods. The security bracket provides an additional layer of protection against tampering or accidental movement of the instrument in shared laboratory spaces.

Applications

• Pharmaceutical API and excipient weighing in larger-batch preparation scenarios
• Analytical chemistry requiring heavier volumetric glassware or sample containers
• Industrial quality control testing of components up to 220 g with milligram-level documentation
• Academic research where a higher capacity analytical balance is needed at an economical price

Why Choose the OHAUS PR224?

Analysts who have outgrown a 120 g capacity balance but do not need a touchscreen platform will find the PR224 an efficient, affordable upgrade. It delivers identical analytical performance to the PR124 across a broader range — backed by the same proven calibration, connectivity, and protection features. Order today to give your team the capacity headroom they need without overspecifying.
