EKitty 4: Method of measuring mass output flow rate

[TinselKoala]

The Harvard Trip Balance is a neat bit of kit. You can "set" it by taring it up as I have done, then when the sample pan reaches that mass, within a few milligrams, the balance "trips" quite definitely -- the sample pan goes down -- and the moment of tripping can be recorded fairly accurately. This allows a reasonably accurate measurement of when a particular mass increment is reached, and thus allows calculation of mass output flow rate. I don't use it that way here but next time I may.
