OHAUS SPX223 AM Scout Portable Balance, 220 g Capacity, 0.001 g Readability

OHAUS SPX223 AM Scout Portable Balance — Milligram Resolution with an Included Draftshield

Taking milligram-level precision into the field is a challenge that requires not just a sensitive sensor, but environmental protection for that sensor. The OHAUS SPX223 AM Scout Portable Balance tackles this with 0.001g readability, an included ABS draftshield, and 80 hours of battery life — delivering analytical-adjacent measurement capability in a portable Scout chassis suitable for gemology, fine chemistry, and specialized sampling far from any benchtop.

Key Features

• 0.001g (1mg) Readability at 220g Capacity: Near-analytical resolution for weighing precious materials, fine reagents, and small biological samples requiring milligram discrimination.
• Included ABS Draftshield: Standard on this 1mg model, the draftshield encloses the 93mm pan to block air currents that would otherwise destabilize sub-milligram readings.
• 80-Hour Battery Life: AA battery power sustains full-day field operations without requiring access to mains power.
• ±0.003g Linearity and 0.002g Repeatability: Performance specifications consistent with genuine milligram accuracy, not a nominal claim with wider actual tolerance.
• 1.5-Second Stabilization: Acceptable for field use at the 1mg level — fast enough for productive workflows while allowing the draftshield to do its job.
• Mechanical and Software Overload Protection: Redundant protection keeps sensitive internal components safe during transport and use in non-lab settings.
• Multiple Weighing Application Modes: Check weighing, percent weighing, totalization, and display hold support a range of field measurement tasks beyond basic weighing.

Detailed Overview

The OHAUS SPX223 AM Scout Portable Balance is the high-resolution member of the 220g Scout family — differentiated from the SPX222 AM by a ten-fold improvement in readability (0.001g vs. 0.01g) and the addition of the built-in draftshield. That draftshield is not optional: at milligram resolution, even mild air movement introduces enough signal noise to make readings unreliable, and enclosing the pan is the practical solution. The taller 222mm × 103mm × 202mm profile (versus 54mm height for non-draftshield models) accommodates the enclosure without making the instrument impractical to carry. The span calibration mass is included on models with 620g capacity or less, which covers the SPX223 AM, ensuring first-use calibration verification is possible immediately.

Applications

• Precious metals and diamond weighing in the field or at dealer/appraisal locations
• Fine chemical and reagent sample collection at remote research sites
• Pharmaceutical product verification requiring milligram accuracy away from a fixed lab
• Specialized analytical support in forensic or environmental field investigations
