OHAUS NV323 AM Navigator Portable Balance, 320g Capacity, 0.001g Readability, GLP/GMP Compliant

OHAUS NV323 AM Portable Balance — 320 g Navigator Balance with 1 mg Precision and Extended Range

Between the 120 g NV123 AM and the 220 g NV223 AM sits a gap that the OHAUS NV323 AM Portable Balance bridges with purpose. At 320 g capacity and 0.001 g readability, it gives analysts who routinely work with samples in the 200–320 g range access to milligram accuracy without the compromises of a lower-capacity instrument.

Key Features

• 320 g Capacity at 0.001 g Readability: The broadest milligram-precision range in the Navigator portable series — 60% wider than the 220 g NV223 AM.
• 0.002 g Typical Repeatability: Sub-2 mg repeatability across the full 320 g range supports reliable analytical results on heavier small samples.
• 93 mm Circular Pan: Compact precision pan suited to the weighing vessels used in milligram-level work — vials, crucibles, and small weighing boats.
• 200-Hour Battery Runtime: Four C-cell batteries sustain prolonged portable operation in field or multi-room laboratory environments.
• 2.5-Second Stabilization Time: Appropriate response for milligram resolution; faster than many fixed analytical balances at this precision level.
• GLP/GMP Connectivity Ready: Optional RS232, USB Device, and Ethernet ports for regulated data output and printing.
• Overload Protection: Mechanical and software protection up to 4× the rated capacity.

Detailed Overview

The NV323 AM extends milligram precision into the 320 g territory that the NV223 AM cannot cover, making it valuable for analysts who weigh larger-volume micro-samples — such as multi-component formulation batches where individual additions are in the sub-gram range but cumulative mass approaches 300 g. The ±0.005 g linearity holds accuracy firmly throughout the range. The 93 mm pan shared with other 1 mg Navigator models confirms the consistent physical platform across milligram-precision variants. Battery life of 200 hours on four C-cells is identical to the NV223 AM; both pay the same energy cost for milligram weighing cell sensitivity. The ABS housing and stainless steel pan construction deliver durability appropriate for laboratory and light industrial environments. Seven measurement units — grams, ounces, troy ounces, carats, grains, pennyweight, and newtons — serve the diverse sectors where 1 mg portable accuracy is required.

Applications

• Multi-component pharmaceutical formulations with combined mass above 220 g
• Precision analytical weighing in portable or remote lab contexts
• Gemological and precious metal weighing of larger assemblies
• Micro-sample preparation where individual portions require milligram confirmation

Why Choose the OHAUS NV323 AM?

When the NV223 AM runs out of range before the sample runs out of mass, the NV323 AM steps in — providing an additional 100 g of capacity without sacrificing 1 mg precision or portability. Add to cart to cover a wider milligram-precision weighing range in the field or at the bench.
