OHAUS NV422 AM Navigator Portable Balance, 420g Capacity, 0.01g Readability, GLP/GMP Compliant

OHAUS NV422 AM Portable Balance — 420 g Navigator Balance with 0.01 g Readability and Fast Stabilization

For laboratory and field applications requiring centigram precision across a 420 g range, the OHAUS NV422 AM Portable Balance delivers — and its 1.5-second stabilization time makes it the fastest-settling 0.01 g Navigator model, shortening per-sample cycle time in high-throughput environments.

Key Features

• 420 g Capacity at 0.01 g Readability: Covers a useful midrange — above small-sample analytical work and below heavy industrial loads — with centigram precision.
• 1.5-Second Stabilization: Faster than any other 0.01 g model in the Navigator portable series, supporting higher sample throughput per hour.
• 0.02 g Repeatability and Linearity: Consistent centigram accuracy both as a repeated-measurement specification and as a linearity limit across the full range.
• 270-Hour Battery Life: Longest battery endurance among 0.01 g Navigator portable models — excellent for extended fieldwork or multi-shift operation.
• 145 mm Circular Pan: Compact pan diameter matched to the capacity tier and to the sample vessels commonly used in centigram-precision work.
• GLP/GMP Data Output Capable: Optional RS232, USB, and Ethernet accessories integrate the balance into compliant documentation workflows.
• Four Application Modes: Weighing, parts counting, percent weighing, and checkweighing are all accessible without additional software.

Detailed Overview

The NV422 AM occupies a distinct position within the Navigator lineup: it offers the largest capacity among the 0.01 g portable models (420 g versus 220 g and 320 g) while achieving the fastest stabilization (1.5 s) and the longest battery life (270 hours). This combination makes it particularly well-suited to quality control environments where centigram accuracy is required across a wide variety of sample sizes and operators are expected to process many samples per shift. The 0.02 g linearity — tighter than the 0.05 g linearity seen on the higher-capacity NV2202 AM and NV3202 AM — reflects the more precise weighing cell. Seven measurement units cover grams, ounces, troy ounces, carats, grains, pennyweight, and newtons. The ABS housing, stainless steel pan, transportation lock, and adjustable leveling feet are consistent with the rest of the Navigator portable family.

Applications

• Quality control of pharmaceutical and cosmetic formulations
• Centigram-precision jewellery and precious metal verification at 420 g range
• Industrial checkweighing with a fast throughput requirement
• Food and ingredient portion verification in production environments
