Thermocouple wire can be fabricated into accurate and dependable temperature sensors by joining the thermo elements at the sensing end utilizing the “Crimp- Junction”. Made of pure nickel, the “Crimp-Junction” offers a convenient method for fabricating thermocouples at the point of use. Two sizes, 24-gage and 20-gage, are available in order to accommodate the most utilized wire sizes. The Crimp-Tool has the capability to form either size.
