六、發射率
大多数有机材料和涂有油漆或氧化的表面具有

0 . 1 -1 . 0

的发射率,

 

测温仪中发射率为

0 . 1 - 1 . 0

可调,

 

测量光亮或抛光的金属表面将

导致读数不准。解决方法是用黑胶带或黑色油漆盖住测定表面,当胶
带达到与覆盖材料相同的温度后,测定胶带或油漆的表面温度

**

注意

** 

不要使測試光亮的金屬表面

(

如不銹鋼或鋁

)

,本產品無法隔著玻璃測

試,測試到的溫度為玻璃表面的溫度,蒸氣、煙霧,灰塵會影響測量
的精準度。

七、距離系數比
測量目標越遠,測試的範圍越大,距離與測量範圍的比值常用

D:S

表示。當測量距離為

36cm

時,測量範圍的直徑為

22.5mm

,測溫槍

量測的是量測範圍的平均溫度。
