Kobata Liquid-filled Thermometers Indicating Thermometers
Made in Japan
Manufacturer: Kowata Keiki Seisakusho Co., Ltd.
Product name: Thermometers
This indicating thermometer, a liquid-filled pressure type, operates on the principle that a filled liquid expands and contracts with temperature changes.
There are two types: the mercury-filled types, which therefore contain mercury, and the non-mercury-filled types, which instead use non-mercury organic liquid.
