3 kg Balance PT

Description

Top-loading balance and small scale proficiency test using 1 kg and 2 kg test weights. Calibrate your balance with your own weights, then report readings and uncertainty at 1 kg, 2 kg, and 3 kg. Requires a balance with at least 3,000 g capacity and 0.01 g readability.

How this PT is scored

Each reported value is compared with the Lake Balance reference value using the En number, which accounts for both your expanded uncertainty and ours. Results are available in the customer portal. See Scale, balance & mass proficiency testing, all calibration PT programs, and our ISO/IEC 17043 certificate & scope.
