玻璃棒式溫度計主要分為精度0.1精密溫度計，精度0.01℃高精密溫度計，另外一等標準溫度計和二等標準溫度計也被列為精密溫度計的范疇。?

工業(ye)用玻璃棒式水銀溫度計注(zhu)意事項(xiang)：

1、使用前應進行校驗(可以采用標準液溫多支比較法進行校驗或采用精度更高級的溫度計校驗)。
2、不允許使用溫度超過該種溫度計的大刻度值的測量值。
3、溫度計有熱慣性，應在溫度計達到穩定狀態后讀數。讀數時應在溫度凸形彎月面切線方向讀取，目光直視。
4、水銀溫度計應與被測工質流動方向相垂直或呈傾斜狀。
5、水銀溫度計常常發生水銀柱斷裂的情況，消除方法有：
（1）冷修法：將溫度計的測溫包插入干冰和酒精混合液中(溫度不得超過-38℃)進行冷縮，使毛細管中的水銀全部收縮到測溫包中為止。
（2）熱(re)修法：將溫(wen)(wen)(wen)(wen)度(du)(du)計(ji)(ji)緩(huan)慢插溫(wen)(wen)(wen)(wen)度(du)(du)略高于(yu)測量(liang)上限的恒溫(wen)(wen)(wen)(wen)槽(cao)中(zhong)(zhong)，使水銀(yin)斷裂部分與(yu)整個水銀(yin)柱連(lian)接起來，再緩(huan)慢取出溫(wen)(wen)(wen)(wen)度(du)(du)計(ji)(ji)，在空氣中(zhong)(zhong)逐漸冷(leng)至室溫(wen)(wen)(wen)(wen)。

測溫技巧
    當測量發光物體表面溫度時，如鋁和不銹鋼，表面的反射會影響紅外測溫儀的讀數。在讀取溫度前， 可在金屬表面放一膠條，溫度平衡后，測量膠條區域溫度。
    要想紅外測溫儀可從廚房到冷藏區來回走動仍能提供精確的溫度測量，就要在新環境下經過一段時間以達到溫度平衡后再測量。將測溫儀放在經常使用的場所。
    用(yong)紅外(wai)測溫儀(yi)讀(du)取流體食品(pin)的(de)內部溫度，像湯或醬，必須攪動，然后(hou)就(jiu)可測表面溫度。使測溫儀(yi)遠離蒸汽，以(yi)避免污染透鏡，導(dao)致(zhi)不正確的(de)讀(du)數。

使用方法
1．先觀察量程，分度值和0點，所測液體溫度不能超過量程；
2．溫度計的玻璃泡全部浸入被測的液體中，不要碰到容器底或容器壁；
3．溫度計玻璃泡浸入被測液體后要稍等一會，待溫度計的示數穩定后再讀數；
4．讀數時溫度計(ji)(ji)的(de)玻璃泡要繼續留在液體中，視(shi)線要與溫度計(ji)(ji)中液柱的(de)上表面(mian)相平。
