Nga Rahi Waea Chromel Alumel Bare Waea mo K Momo Temperature Sensor
TYPE K (CHROMEL vs ALUMEL) ka whakamahia ki te whakapouri, ki te koretake, ki te whakamaroke ranei i nga hau whakaheke. He wa poto noa te whakakitenga ki te korehau. Me whakamarumaru mai i nga hau whanariki me te waikura iti. He pono me te tika i nga wera teitei.
