Temperature measuring instrument for soldering iron

半田こて用温度計測装置

Abstract

PROBLEM TO BE SOLVED: To precisely detect an iron tip temperature of a soldering iron and prevent a solder from being adhered to a device by disposing two different kinds of metal materials forming a thermocouple with these materials spaced with each other and bringing these different kinds of metal materials into electrical contact with each other by an iron tip. SOLUTION: A temperature measuring head is abutted with an ion tip of a soldering iron of an object to be measured and is intended for detecting a temperature thereof and comprises a pair of wire rods 6a and 6b consisting of different kind of metal materials forming a support cover 4, a wire rod expansion holder 5, and a thermocouple. The support cover 4 is provided with a leg part 4a and is removably attached to a grip part. The wire expansion holder 5 expands the wires 6a and 6b, an alloy essentially containing nickel or chrome, for example is employed for the wire 6a, and an alloy essentially containing nickel, for example, is employed for the wire 6b. This thermocouple has relatively great electromotive force and is capable of measuring a temperature stably under a temperature of 450°C or less that is an operating temperature range of the soldering iron.
