OHAUS NV222 AM Navigator Portable Balance, 220g Capacity, 0.01g Readability, GLP/GMP Compliant

OHAUS NV222 AM Portable Balance — 220 g Navigator Balance with Centigram Precision

Centigram precision in a small-capacity portable balance opens possibilities for jewellery assessors, pharmacists, and precision educators who need more resolution than 0.1 g provides but do not require the full milligram accuracy of a semi-analytical instrument. The OHAUS NV222 AM Portable Balance delivers 0.01 g readability and 0.01 g typical repeatability across a 220 g range.

Key Features

• 0.01 g Readability and Repeatability: True centigram performance verified by a 0.01 g repeatability specification — not merely a display resolution claim.
• 1-Second Stabilization Time: Faster settling than other 0.01 g Navigator models in this capacity range, supporting high-sample-volume workflows.
• 220 g Capacity: Focused on the sample mass range where centigram resolution is most practically useful — precious metals, small compounds, and pharmaceutical doses.
• 270-Hour Battery Life: Superior battery endurance relative to the NV222 AM's precision level supports extended portable or off-grid operation.
• 0.02 g Linearity: Consistent accuracy across the full 220 g span ensures results are as reliable at 200 g as they are near zero.
• Application Functions: Weighing, parts counting, percent weighing, and checkweighing address a broad range of practical tasks.
• 145 mm Circular Pan: Sized to match the compact capacity profile — suitable for vials, small dishes, and gemstone holders.

Detailed Overview

Within the Navigator 220 g range, the NV222 AM occupies the middle precision tier between the NV221 AM (0.1 g) and the NV223 AM (0.001 g). Its 1-second stabilization is notably quick for a 0.01 g balance, making it practical for high-throughput small-mass verification tasks. The 145 mm circular pan is slightly different from the rectangular pan found on higher-capacity Navigator models, reflecting the smaller footprint appropriate for 0.01 g work at this capacity. Battery life of 270 hours on four C-cell cells is excellent, and the optional communication ports (RS232, USB, Ethernet) ensure compatibility with laboratory data management and GLP/GMP reporting requirements. Seven measurement units cover the jewellery, pharmaceutical, and scientific sectors where centigram accuracy is the standard.

Applications

• Precious metal, gem, and jewellery piece verification
• Pharmaceutical dose weighing and verification
• Chemical sample preparation at small mass scales
• Educational precision weighing exercises
