ABSTRACT:
An electronic balance devised so that the weighing pan of the balance may settle down fast to make the balance indicate a correct value of measurement quickly without being long disturbed by the air turbulence arising when the door of the weighing pan protecting chamber of the balance is opened and continuing for a while after the door has been closed. This electronic balance is provided witha heater on the base portion of the weighing pan protecting chamber so that the heater is located just below the door of the chamber. The heater generates hot air streams rising upward therefrom along the outer surface of the door. When the door is opened, the air streams play a role of an air curtain to prevent a possible air exchange between the hotter chamber warmed by the electronic circuit of the balance and the cooler surrounding atmosphere.
