OHAUS CR221 Compass CR Portable Balance, 220g Capacity, 0.1g Readability, Stackable Slim Design

OHAUS CR221 Portable Balance — Fine 0.1g Readability in a Compact Battery-Powered Design

Portable precision at 0.1g resolution is genuinely useful in the field—for soil science, botanical sampling, or chemistry practicals far from a lab bench. The OHAUS CR221 Compass CR Portable Balance packs 220g capacity and 0.1g readability into a slim, stackable housing that runs 300 hours on a set of AA batteries. When every gram matters but a power outlet is nowhere in sight, the CR221 fills the gap.

Key Features

• 0.1g Readability at 220g Capacity: Finer resolution than the larger CR2200 model, appropriate for botanical, soil, and analytical field applications where sample masses are small.
• 300-Hour Battery Endurance: Three AA batteries sustain operation through extended field sessions or entire semesters of classroom use without replacement anxiety.
• Slim Stackable ABS Housing: Compact profile nests multiple units for organized storage in a instrument cabinet or portable field kit.
• 132 mm × 125 mm Platform: Accommodates small sample bags, weighing boats, and field containers typical of light analytical and educational tasks.
• LCD Display: Simple readout presents mass in grams or ounces clearly, with no menu navigation required for basic weighing.
• Transportation Lock: Secures the measurement mechanism against shock and vibration during road travel or backpack transport.
• AC Adapter Compatible: Optional AC connection for bench-mode use when power is available, making the CR221 a dual-purpose portable and benchtop unit.

Detailed Overview

The OHAUS CR221 Compass CR Portable Balance differentiates itself from the CR2200 through its 0.1g readability—a step finer than the 1g resolution of the larger model. This makes it the appropriate choice when sample masses are in the low hundreds of grams and small differences in mass are significant, as in plant tissue analysis, small-animal ecological surveys, or introductory quantitative chemistry experiments. The 2-second stabilization time and slip-resistant feet provide stable readings even on uneven field surfaces or outdoor tables. At 0.4kg net weight, it travels in a field pack without burden. Units from the CR series stack flat for classroom storage, making management of a set of 20 or 30 instruments far easier than with conventional bench-mount designs.

Applications

• Botanical and ecological field sampling
• Secondary and university chemistry practicals
• Small-sample environmental monitoring and soil analysis
• Portable QC inspection for lightweight packaged goods
