OHAUS NV123 AM Navigator Portable Balance, 120g Capacity, 0.001g Readability, GLP/GMP Compliant

OHAUS NV123 AM Portable Balance — 120 g Navigator Balance with 1 mg Readability

Milligram-level precision in a battery-powered portable balance is a rare combination. The OHAUS NV123 AM Portable Balance achieves exactly that — 0.001 g readability across a 120 g range — delivering the fine resolution typically associated with laboratory analytical balances in a unit that weighs just 1 kg and runs on four C-cell batteries.

Key Features

• 0.001 g (1 mg) Readability: Milligram resolution enables precise small-mass weighing for analytical, pharmaceutical, and jewellery applications on the go.
• 0.002 g Typical Repeatability: Consistent performance across repeated measurements confirms reliable results in demanding applications.
• 200-Hour Battery Operation: Long-duration battery life on four C-cell batteries supports a full working week or more of field or lab use.
• 120 g Capacity at Milligram Precision: Covers routine analytical weighing needs without requiring a separate balance for heavier samples.
• 93 mm Circular Pan: Compact pan diameter suits small sample containers, watch glasses, and vials used in analytical work.
• Parts Counting and Percent Weighing Modes: Application functions increase the instrument's utility for inventory and quality control tasks.
• Checkweighing Function: Set upper and lower limits to quickly verify whether samples fall within acceptable mass tolerances.

Detailed Overview

The NV123 AM is the highest-resolution model in the Navigator portable series, and its 0.001 g readability places it at the boundary between portable and semi-micro analytical performance. The 2.5-second stabilization time reflects the finer weighing cell required at this resolution level. At 1 kg total weight, it is genuinely field-portable, and the included AC adapter means it can operate from mains power in fixed locations as well. The 93 mm circular pan is smaller than the rectangular platform on higher-capacity Navigator models, reflecting the typical sample sizes used in milligram-precision work. A transportation lock protects the mechanism during transit, and the leveling bubble and adjustable feet ensure a stable horizontal setup on any surface. Seven weighing units covering grams, carats, grains, troy ounces, pennyweight, newtons, and ounces address the jewellery, pharmaceutical, and scientific use cases where 1 mg precision matters most.

Applications

• Milligram-precision dispensing in pharmaceutical compounding
• Precious metal and gemstone weighing in jewellery settings
• Small-mass analytical weighing in portable or fieldwork contexts
• Sample preparation for chromatography and spectroscopy

Why Choose the OHAUS NV123 AM?

Analysts and technicians who need milligram accuracy outside a fixed laboratory — or simply cannot justify a large analytical balance footprint — will find the NV123 AM a uniquely capable solution. Add to cart to bring 1 mg precision wherever your work takes you.
