OHAUS NV223 AM Navigator Portable Balance, 220g Capacity, 0.001g Readability, GLP/GMP Compliant

OHAUS NV223 AM Portable Balance — 220 g Navigator Balance with 0.001 g Milligram Resolution

Milligram precision at 220 g capacity in a battery-portable unit is a rare specification. The OHAUS NV223 AM Portable Balance achieves it — delivering 0.001 g readability and 0.002 g typical repeatability for analytical tasks that require milligram-level accuracy but cannot always be performed at a fixed laboratory workstation.

Key Features

• 0.001 g (1 mg) Readability: Genuine milligram resolution makes the NV223 AM suitable for pharmaceutical compounding, gemology, and precise formulation work.
• 0.002 g Typical Repeatability: Sub-2 mg repeatability confirms the balance performs at its stated resolution under real-world conditions.
• 220 g Maximum Capacity: Broader range than the 120 g NV123 AM, accommodating slightly heavier samples while maintaining milligram accuracy.
• 93 mm Circular Pan: Compact pan sized for the sample vessels — vials, weighing boats, crucibles — associated with milligram-precision work.
• 200-Hour Battery Life: Supports extended remote or field operation without mains power connection.
• 2.5-Second Stabilization: Appropriate settling time for milligram-level resolution; faster than many stationary analytical balances.
• GLP/GMP Data Output Capable: Optional RS232, USB Device, and Ethernet connectivity supports regulated documentation workflows.

Detailed Overview

The NV223 AM extends the Navigator 220 g family to its highest precision level. Compared to the NV222 AM (0.01 g), the NV223 AM achieves a 10× improvement in resolution at a 200-hour battery life — slightly shorter than the 270-hour NV222 AM figure, consistent with the more sensitive weighing cell. The 93 mm circular pan matches the platform used on the NV123 AM (120 g / 1 mg), confirming the physical configuration is optimised for the small, precise sample masses involved. The ±0.005 g linearity across 220 g is a strong specification for a portable instrument. Seven measurement units — grams, ounces, troy ounces, carats, grains, pennyweight, and newtons — address the sectors where 1 mg portable accuracy matters most. A transportation lock safeguards the sensitive weighing cell during transit between locations.

Applications

• Mobile pharmaceutical compounding and dose verification
• Gemstone and precious metal milligram assessment in field settings
• Portable analytical weighing in research and forensic contexts
• Micro-sample preparation for chromatographic analysis

Why Choose the OHAUS NV223 AM?

Analysts who work across multiple sites and need milligram accuracy without carrying a full stationary analytical balance will find the NV223 AM uniquely well-suited to their requirements. Add to cart to gain portable 1 mg precision with the reliability of the Navigator platform.
