OHAUS CX221P Compass CX Portable Balance, 220g Capacity, 0.1g Readability, 1000-Hour Battery Life

OHAUS CX221P Compass CX Portable Balance — Fine 0.1g Readability for Field and Classroom Use

Light samples demand finer resolution than most portable balances offer. The OHAUS CX221P Compass CX Portable Balance provides 0.1g readability within a 220g range, running on a single charge of three AA batteries for over 1001 hours. Botanists, field chemists, and science educators working with small sample masses get precise results without the weight, complexity, or power dependency of laboratory instruments.

Key Features

• 0.1g readability at 220g capacity: Ten times the resolution of the CX2200P, suited to fine sample materials—dried plant matter, soil cores, small fauna specimens—where gram-level precision is insufficient.
• 1001-hour AA battery operation: Extended battery endurance makes the CX221P deployable for entire field seasons without battery replacement becoming a logistical concern.
• Ultra-compact 0.5kg form factor: At half a kilogram, the CX221P is easily pocketed or slipped into a sample collection kit, reducing the burden of extended fieldwork.
• Backlit LCD for field visibility: White backlight ensures legibility at dusk or in shaded forest and indoor sampling environments where unlit displays wash out.
• Stainless steel pan: Resists chemical exposure from biological samples and field-collected materials, maintaining surface integrity across extended outdoor deployments.
• Simplified two-button interface: Minimal controls allow accurate operation by occasional users—students, volunteers, and non-technical field staff—with minimal instruction.
• Optional AC adapter: Converts the CX221P into a bench balance when mains power is accessible, extending its value beyond pure field use.

Detailed Overview

The CX221P is the smallest-capacity member of the Compass CX portable family. Compared to the CX2200P and CX5200-series, it sacrifices capacity in exchange for finer 0.1g resolution, matching the needs of ecological research, botanical analysis, and science education where sample masses routinely fall in the sub-50g range. Three supported units—gram, ounce, and Newton—cover the standard field and classroom measurement conventions. Display Hold mode is particularly useful outdoors: it captures a stable reading and holds it on screen while the analyst transfers focus away from the display. The 1.5-second settling time matches other CX models, confirming consistent design across the series. At only 201 mm × 135 mm footprint, the CX221P fits even tight bench or desk setups when deployed inside.

Applications

• Ecological field research involving small flora and fauna specimen weighing
• Botanical sample collection and pressed specimen mass documentation
• Science education laboratory exercises requiring portable, battery-operated scales
• Pharmaceutical field quality spot checks where samples are small and portability is prioritised
• Gemological and mineral specimen weighing at trade shows or remote collection sites

Why Choose the OHAUS CX221P?

The CX221P is designed for researchers and educators who need tenth-of-gram precision in environments where power sources are unavailable or impractical. Its thousand-plus-hour battery life means it outlasts field deployments that would exhaust rechargeable instruments. Order today to add finer portable precision to your field kit or teaching laboratory.
