I have 9 new probe covers remaining. There is no box or instruction manual. In accordance with the rules, only the case and replacement covers are listed. Please understand that these items have been stored at home before purchasing. [Description] Temperature measurement in as little as 1 second. A gentle ear thermometer for children. Equipped with "Perfect Sensing Function". Actual measurement type <Ear only> Even when it's difficult to understand the direction of the eardrum, the "Perfect Sensing Function" provides peace of mind. Ear thermometers measure the temperature of the eardrum, which is the highest temperature in the ear. Therefore, if not inserted correctly into the ear (not facing the direction of the eardrum), the temperature of the inner wall of the ear canal will be measured. By inserting the probe into the ear and moving it, the "Perfect Sensing Function" memorizes the highest temperature during measurement and displays it as the measurement result, providing peace of mind even when the direction of the eardrum is difficult to understand.
