ʻAno K (CHROMEL vs. ALUMEL)hoʻohana ʻia i nā lewa oxidizing, inert a i ʻole maloʻo. ʻO ka ʻike ʻana i ka vacuum i kaupalena ʻia i nā manawa pōkole. Pono e pale ʻia mai nā lewa sulfurous a me nā lewa oxidizing liʻiliʻi. Hilinaʻi a pololei hoʻi i nā mahana kiʻekiʻe.
E kākau i kāu leka ma aneʻi a hoʻouna mai iā mākou
