ABSTRACT:
An electronic balance made free from an error due to ambient temperature variations is disclosed. The balance is characterized in that an electromagnetic force transducer used therein is encased in a constant-temperature casing provided with through hole at the bottom through which a force transmitting means penetrates connecting between a weighing tray and an electromagetic force-coil of said electromagnetic force-transducer. The constant-temperature casing is temperature-controlled at a constant temperature higher than room temperatures to keep said electromagnetic force-transducer free from the effect of ambient room temperature variations.
