Uhlobo lwe-Thermocouple K Alumel /Induku ye-Chromel/ Induku / Ibha 6mm 8mm 9mm 10mm 12mm
I-TYPE K (CHROMEL vs ALUMEL) isetshenziswa ezindaweni ezikhipha i-oxidation, i-inert noma ezomile. Kumelwe ivikelwe ezindaweni ezikhipha i-oxidation kanye nezikhipha i-oxidation kancane. Ithembekile futhi inembe kakhulu emazingeni okushisa aphezulu.

Isicelo se-K Rod esingu-0.5″ 12.7mm KP Chromel KN Alumel Thermocouple Type K Rod
Isici sohlobo lwe-K ukuthi lunamandla amakhulu okulwa nokubola, futhi kufanele lusetshenziswe njalo emoyeni ongenayo i-oxidizing kanye ne-inert. Izinga lokushisa lokusetshenziswa kwesikhathi eside lingu-1000℃ kanye no-1200 ℃ wesikhathi esifushane. Lusetshenziswa kakhulu phakathi kwawo wonke ama-thermocouple; (alukwazi ukusetshenziswa ukunciphisa umoya wegesi).
