OHAUS NV221 AM Navigator Portable Balance, 220g Capacity, 0.1g Readability, GLP/GMP Compliant

OHAUS NV221 AM Portable Balance — Compact 220 g Navigator Balance for Quick, Lightweight Weighing

Some applications call for a compact, low-capacity portable balance that can be picked up and moved without a second thought. The OHAUS NV221 AM Portable Balance serves exactly that need — 220 g capacity at 0.1 g readability, housed in the same 1 kg Navigator body with a generous 270-hour battery life for untethered operation.

Key Features

• 220 g Capacity: Ideal for small sample masses encountered in jewellery, education, and low-volume laboratory work.
• 0.1 g Readability with 1-Second Stabilization: Fast response at a resolution appropriate for applications where centigram precision is not required.
• 270-Hour Battery Runtime: The longest battery life in the 0.1 g Navigator range makes it reliable for extended use without mains power.
• Compact and Lightweight: At 1 kg and 230 mm × 70 mm × 204 mm, it fits into a carrying case, storage drawer, or tight bench space with ease.
• GLP/GMP Output Ready: Connectivity accessories (RS232, USB, Ethernet) allow integration with laboratory data systems when traceability is required.
• Applications Suite: Weighing, parts counting, checkweighing, and percent weighing functions built in.
• 7 Weighing Units: Grams, ounces, troy ounces, carats, grains, pennyweight, and newtons support diverse usage scenarios.

Detailed Overview

The NV221 AM carves its niche within the Navigator lineup as the entry-level capacity model with 0.1 g discrimination. Its 220 g range makes it unsuitable for heavy industrial use, but for applications where sample masses are routinely small — educational weighing exercises, jewellery assessment, small reagent portions — this is exactly the right instrument. The large rectangular stainless steel pan (144 mm × 190 mm) provides ample space relative to the capacity range, accommodating flat or irregularly shaped items. Four C-cell batteries deliver 270 hours of runtime, making recharging or battery replacement a rare event. The standard Navigator housing — ABS body, transportation lock, slip-resistant adjustable feet — provides the durability expected in a balance that may be moved frequently between settings.

Applications

• Jewellery and small metal piece weighing
• Teaching laboratory general weighing exercises
• Small reagent portion preparation
• Retail weighing of small items
