200 g Analytical Balance PT

Description

Analytical balance proficiency test using a set of test weights totaling 200 g. Calibrate your balance with your own weights, then report readings and uncertainty at 20 g, 30 g, 50 g, 100 g, and 200 g. Requires a balance with at least 200 g capacity and 0.1 mg 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.
