A na-eji Thermometer Standard Platinum Resistance Thermometer maka nkwụghachi n'ụdị ọnọdụ okpomọkụ nke 13.8033k-961.8 Celsius C, ma jiri ya mee ihe dịka ọkọlọtọ mgbe a na-anwale ụdị temometa dị iche iche na temometa dị elu.N'ime mpaghara okpomọkụ dị n'elu, a na-ejikwa ya ozugbo maka ịlele okpomọkụ nke ịdị elu dị elu.

Thermometer Standard Platinum Resistance Thermometer na-atụ okpomọkụ dịka mgbanwe na-agbanwe mgbe niile nke okpomoku nguzogide nke platinum.

Dabere na ụkpụrụ nke ITS90, T₉₀A na-akọwa ya site na temometa platinum mgbe ntụpọ atọ (13.8033K) nke itule nitrogen ruru n'ogo okpomọkụ nke ebe na-ajụ ọlaọcha.A na-edepụta ya site n'iji otu ebe a na-atụ oyi akọwapụta chọrọ yana ọrụ ntụaka yana ọrụ ntụgharị nke interpolation okpomọkụ.

A na-ekewa mpaghara okpomọkụ dị n'elu n'ime ọtụtụ ma kpebie ịrụ ọrụ nke ọma n'ime mpaghara okpomọkụ site na ụdị dị iche iche nke nhazi nke temometa.

Hụ nkọwa thermometers na tebụl n'okpuru:

Cheta na: The Rtp nke n'elu thermometers bụ 25 ± 1.0Ω.The mpụga dayameta nke quartz tubes bụ φ7 ± 0.6mm.our factory na-arụpụtakwa na platinum temometa na okpomọkụ mpaghara nke 83.8058K ~ 660.323 ℃ dị ka na-arụ ọrụ isi ọkọlọtọ ngwá ọrụ.
