OHAUS PR223/E PR Series Precision Balance, 220g Capacity, 0.001g Readability, RS232 Connectivity
OHAUS PR223/E PR Series Precision Balance — 0.001g Readability with RS232 Connectivity
Getting consistent sub-milligram results at an accessible price point is the defining capability of the OHAUS PR223/E PR Series Precision Balance. With a 220g capacity and 0.001g readability, this balance supports analytical-adjacent weighing tasks — from reagent preparation to jewelry assessment — backed by RS232 data output for direct integration with laboratory software or printers.
Key Features
- 0.001g Readability on a 220g Capacity: Fine resolution suited to milligram-level sample preparation, jewelry weighing, and precise reagent dispensing without stepping up to a full analytical balance.
- Included Glass Draftshield: A removable glass enclosure with sliding door isolates the pan from air currents, maintaining stability and reliability during fine-mass measurements.
- RS232 Connectivity: Serial output transmits results directly to a PC, LIMS, or label printer, supporting paperless data collection and GLP-compliant record-keeping.
- Backlit LCD Display: Clear character display with adjustable brightness ensures readability across different lighting conditions and long working sessions.
- Auto-Tare and Environmental Filters: User-selectable filters handle mild vibration or drafts, while auto-tare accelerates multi-sample workflows.
- Span Calibration Points: User-selectable calibration reference points allow the balance to be tuned to in-house reference weights, ensuring traceability to measurement standards.
- Security Bracket and Calibration Lock: Physical and software security features prevent unauthorized changes to calibration or configuration in regulated or shared laboratory environments.
Detailed Overview
The OHAUS PR223/E Precision Balance occupies a practical niche between a basic top-loading scale and a full analytical instrument. At 0.002g linearity and 2-second stabilization time, it handles formulation, parts counting, and percentage weighing tasks with the accuracy that quality-control and educational environments require. The removable stainless steel pan facilitates cleaning between samples, and the pan size of 120 mm accommodates standard laboratory vessels and weighing boats. An integrated weigh-below hook enables density determination when combined with an appropriate suspension kit, extending the unit's functionality beyond simple mass measurement. GLP/GMP-compatible data output with project and user ID fields supports regulatory documentation requirements in pharmaceutical, food, and industrial quality settings. The compact ABS housing keeps the instrument lightweight at 4.5 kg, making relocation easy within a lab or between workstations.
Applications
- Reagent and chemical preparation in analytical labs
- Jewelry and precious metal verification
- Parts counting for small components
- Educational laboratory exercises requiring milligram resolution
