OHAUS EX223N Explorer Precision Balance, 220g Capacity, 0.001g Readability, AutoCal, NTEP Certified, Touchscreen

OHAUS EX223N Precision Balance — 220g Capacity with 1mg Readability and AutoCal

For analytical routines where sub-milligram resolution matters, the OHAUS EX223N Precision Balance provides a 220 g working range at 0.001 g readability. AutoCal internal calibration keeps the balance traceable without manual weight handling, and the included draftshield guards the 130 mm pan against airflow disturbances that erode measurement confidence.

Key Features

• AutoCal Internal Calibration: A built-in motorized calibration weight activates automatically when temperature changes are detected, maintaining accuracy within ±0.002 g without operator intervention.
• Draftshield Included: The glass enclosure around the weighing chamber reduces the influence of air currents on the 130 mm stainless steel pan, sustaining repeatability of 0.001 g in open-bench environments.
• NTEP & Measurement Canada Certified: Legal-for-trade approval at a certified readability of 0.01 g supports use in regulated pharmaceutical, gemological, and commercial weighing contexts.
• 5.7-Inch Full-Color VGA Touchscreen: A bright, touch-responsive display provides instant access to all application modes and result display without requiring a separate keyboard or function buttons.
• 1-Second Stabilization for High Throughput: Fast settling makes this balance well suited to repetitive analytical tasks—sample preparation, formulation checking, or pipette calibration—where cycle time compounds across a full work shift.
• 19 Units of Measurement: Covers grams, milligrams, carats, grains, troy ounces, tolas, and 13 additional units to serve diverse laboratory, gemological, and trade applications with a single instrument.
• USB & RS232 Connectivity: Wired interfaces enable direct output to LIMS, GLP printers, and data-capture software; optional Ethernet adds network data management.

Detailed Overview

Laboratories that need fine-resolution weighing under 220 g will find the OHAUS EX223N Precision Balance a dependable and efficient instrument. The combination of AutoCal and the included draftshield addresses the two most common sources of measurement error at the milligram level—temperature drift and air currents—without demanding constant attention from the operator. Stainless steel pan construction withstands chemical exposure and daily cleaning, while the full-color VGA touchscreen supports 15-plus applications including density determination, differential weighing, SQC statistics, and pipette adjustment. The balance's compact housing (393 × 350 × 230 mm with the draftshield) fits standard lab bench configurations, and the operating temperature range of 10–30 °C covers typical climate-controlled workspaces. With typical repeatability matching the stated 0.001 g readability, results remain consistent across multiple operators and work sessions.

Applications

• Pharmaceutical compounding, raw-material verification, and dosage preparation
• Gemological and precious-metal weighing in certified carat measurements
• Pipette adjustment and calibration verification in analytical labs
• Density determination using OHAUS's integrated calculation routine
• Educational and research weighing requiring traceable milligram data
