黑體爐如何選擇溫度：我們知道，黑體爐溫度范圍廣，如何選擇適合自己的黑體爐，以及選擇合適的溫度段呢？上海蕓尖智能科技生產(chǎn)的黑體爐就覆蓋了低溫，中溫，高溫等黑體爐，黑體爐的主要工作就是通過物體所輻射的紅外能量來測量該物體的溫度，黑體爐可以分為超高溫黑體爐、中溫黑體爐、低溫黑體爐（2000℃以上為超高溫黑體爐，500℃-1600℃為高溫黑體爐，室溫-1200℃為中溫黑體爐，-50℃-70℃為低溫黑體爐）等等，每一個(gè)不同的黑體爐所應(yīng)用的行業(yè)也是不一樣的，一般情況下，高溫黑體爐多是被應(yīng)用于工業(yè)中的，而中溫黑體爐和低溫黑體爐多是被應(yīng)用在醫(yī)療行業(yè)中。所以選型時(shí)，就需要根據(jù)自己的被測溫度的范圍來選，假如被測溫度需要測到-50℃-1600℃，那我們就要選擇一臺(tái)低溫黑體爐-50℃-70℃，選擇一臺(tái)室溫-1000℃為中溫黑體爐，選擇一臺(tái)800℃-1600℃為高溫黑體爐，由于每臺(tái)黑體爐的使用范圍，使用精度等特點(diǎn)，這樣選擇就可以完全覆蓋了-50℃-1600℃被測溫度范圍。高溫黑體爐的發(fā)射率是多少？上海腔式黑體爐</p><p
