Description
RADWAG MYA 21.5Y Microbalance, 21 g x 1 µg
The RADWAG MYA 21.5Y is a 21 g x 1 µg (0.000001 g) microbalance with automatic internal calibration, automatic doors and a 10 in color touchscreen. Its standard repeatability is 0.7 µg at 5% of capacity and its USP minimum weight is just 1.4 mg, so it handles filter weighing, pipette calibration and trace-sample work.
The MYA 21.5Y is an Ellipsis-line microbalance with 1 µg readability. It checks its own readiness, compensates for air buoyancy in real time and reminds you when an inspection or periodic accuracy check is due. Ambient Light changes color to show status, process results and alerts. You can run the balance from a connected smartphone, tablet or PC, and the automatic doors and Reflex Level System keep handling to a minimum.
