美國PTC 485CM管材表面溫度計帶有中號夾子 7/8“到1-5/8”（22.2至41.3MM）

這些雙金屬溫度計測量管道的溫度，并且所測量的管道直徑為3/4"到2-3/8"。 在總的溫度范圍內，共計三個不同大小的規格; 小（S），中（M），和大（L），溫度計的精度為滿量程的±2％。

這些溫度計利用對流輻射原理工作。 該儀器是通過推動彈簧夾使其夾在管字上，直至其卡入到位達到迅速固定在管道上的目的。所有管道溫度計都在華氏或攝氏可用。PTC?管道溫度計是在美國制造

華氏溫度 （溫度范圍F 20°到180°)

These bimetal thermometers measure the temperature of pipes, and tubes having diameters of 3/4" to 2-3/8" in diameter. For all temperature ranges, there are three different clip sizes; Small (S), Medium (M), and Large (L). The accuracy of the thermometer is ±2% of full scale range.

These thermometers work on a convection-radiation principle. The instrument is quickly fastened to a pipe by pushing the spring clip over the pipe until it snaps into place. T All Pipe Thermometers are available in Fahrenheit or Celcius. PTC? Pipe Thermometers are made in the U.S.A.
