Why electronic balance is a convenient instrument to measure mass?
they generally measure weight not mass however there are some that uses a system within itself to ‘calculate’ mass by negating the gravitational force (using multiple load cells) exerted on the object from the earth. i.e weight=mg because it is digital it means it can be very accurate depending on the model they often go down to a hundrenth/thousandth of a reading which enables accurate experiments and keeps the answers to uncertainty calculations as low as possible where an analogue scale would have higher uncertainty both from reading error and the ‘+-1 unit rule’ for uncertainties. a little blog answer from scientists on what makes up a Electronic balance can be found here http://www.newton.dep.anl.
