Thermocouple Nooca K Alumel / Chromel Usha / Usha / Bar 6mm 8mm 9mm 10mm 12mm
Thermocouple Nooca K Alumel /Chromel Rod/ Usha / Bar 6mm 8mm 9mm 10mm 12mm
TYPE K (CHROMEL vs ALUMEL) waxaa loo isticmaalaa oksaydhaynta, qallayl ama qallayl dhimista jawiyada. Waa in laga ilaaliyaa jawi baaruud ah oo aan yarayn oksaydhisku. Waa la isku halayn karo oo waxay leedahay sax ah heerkul sare.

Sifada Nooca K ayaa ah in uu leeyahay wax-qabad xooggan oo ka-hortagga oksaydhaynta, waana in si joogto ah loogu isticmaalo jawi oksaydhaysan iyo mid aan firfircoonayn. Heerkulka isticmaalka muddada-dheer waa 1000 ℃ iyo muddada gaaban 1200 ℃. Waa tan ugu ballaaran ee loo isticmaalo dhammaan heerkulbeegyada; (lama isticmaali karo dhimista jawiga gaaska).
