Teitei te Ātete Chromel C mō ngā Oumu Tōhi me ngā Whakamahana Rokiroki
Ko te Chromel C he koranu nikara-kromium austenitic (koranu NiCr) hei whakamahi i ngā pāmahana tae atu ki te 1150°C. Ko te koranu nikara-kromium tino tika o te Chromel C he mea e tohuhia ana e te ātete teitei, te ātete pai ki te waikura me te tino pumau o te āhua. He pai te ngāwari i muri i te whakamahinga, ā, he tino pai te kaha ki te whakarewa.
Taupānga:
- ngā ātete ātete-teitei me ngā ātete potentiometer.
- ngā wae whakamahana hiko (mō te kāinga me te ahumahi).
- ngā oumu ahumahi tae atu ki te 1100°C.
