首先要確認(rèn)紅外線測(cè)溫儀有沒(méi)有計(jì)量，比較好是找當(dāng)?shù)氐挠?jì)量機(jī)構(gòu)進(jìn)行檢定！檢定合格后使用。 </p> <p> 使用中反映問(wèn)題**多的有偏高的，有偏低的，偏低的比較多，這和使用不正確有關(guān)，這里要特別注意~！偏低了和不用有什么區(qū)別？！ </p> <p> 測(cè)量方法 </p> <p> <br /> </p> <p> 先用紅外測(cè)溫儀測(cè)自己或同事的額頭（多人）比較，再測(cè)被測(cè)人相同的位置，多次測(cè)量。注意距離盡量一致，推薦距離（2~5cm），位置也盡量一致。這里可以先用玻璃體溫計(jì)將自己的體溫記錄下來(lái)和紅外測(cè)溫儀保持一致。 </p> <p> 比如測(cè)量額頭，就都測(cè)量額頭，不要測(cè)量不同部位。要測(cè)量暴露在空氣中的位置，有帶帽子或圍巾需要脫掉一會(huì)再進(jìn)行測(cè)量。如果發(fā)現(xiàn)溫度偏差很大，使用其它測(cè)溫設(shè)備確認(rèn)，如玻璃體溫計(jì)、耳溫***等。使用中千萬(wàn)不可照射眼睛。測(cè)量場(chǎng)合盡量保持一致，如在室外，***條也應(yīng)在室外進(jìn)行。

style="text-indent:25px">1，確定測(cè)溫范圍：測(cè)溫范圍是測(cè)溫儀**重要的一個(gè)性能指標(biāo)。每種型號(hào)的測(cè)溫儀都有自己特定的測(cè)溫范圍。因此，用戶的被測(cè)溫度范圍一定要考慮準(zhǔn)確、周全，既不要過(guò)窄，也不要過(guò)寬。根據(jù)黑體輻射定律，在光譜的短波段由溫度引起的輻射能量的變化將超過(guò)由發(fā)射率誤差所引起的輻射能量的變化。2，確定目標(biāo)尺寸:紅外測(cè)溫儀根據(jù)原理可分為單色測(cè)溫儀和雙色測(cè)溫儀（輻射比色測(cè)溫儀）。對(duì)于單色測(cè)溫儀，在進(jìn)行測(cè)溫時(shí)，被測(cè)目標(biāo)面積應(yīng)充滿測(cè)溫儀視場(chǎng)。建議被測(cè)目標(biāo)尺寸超過(guò)視場(chǎng)大小的50]為好。如果目標(biāo)尺寸小于視場(chǎng)，背景輻射能量就會(huì)進(jìn)入測(cè)溫儀的視聲符支干擾測(cè)溫讀數(shù)，造成誤差。相反，如果目標(biāo)大于測(cè)溫儀的視場(chǎng)，測(cè)溫儀就不會(huì)受到測(cè)量區(qū)域外面的背景影響。對(duì)于雙色測(cè)溫儀，其溫度是由兩個(gè)**的波長(zhǎng)帶內(nèi)輻射能量的比值來(lái)確定的。因此當(dāng)被測(cè)目標(biāo)很小，不充滿視場(chǎng)，測(cè)量通路上存在煙霧、塵埃、阻擋，對(duì)輻射能量有衰減時(shí)，都不對(duì)測(cè)量結(jié)果產(chǎn)生重大影響。對(duì)于細(xì)小而又處于運(yùn)動(dòng)或震動(dòng)之中的目標(biāo)，雙色測(cè)溫儀是比較好選擇。這是由于光線直徑小，有柔性，可以在彎曲、阻擋和折疊的通道上傳輸光輻射能量。</p><p>
