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.
