Ultra-Microbalance
AssemblyA null-balance beam carries the sample on a hangdown wire; an optical position transducer senses any tilt and a tare motor restores the beam, the restoring current giving the mass to microgram resolution. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.
