ISR 50-LO是一款数字式、高精度双色测温仪,配备了光纤镜头,用于非接触式温度测量,测温范围700-3000 °C。

该测温仪采用双色原理(比色原理),其中两个相邻的波长用于确定温度。

相对于标准的单色测温仪,这一技术具有以下优点:

  • 测量结果在很宽的温度范围内不受测量物体本身辐射率的影响
  • 测量物体可小于光斑尺寸
  • 测量结果不受测量视域内灰尘及其他污染物的影响,也不会受到被污染视窗的影响

此外,该测温仪可切换至单色模式,作为传统的测温仪使用。
该仪器配备了一根可选装的光纤,在无制冷的条件下最高耐温可达250°C,同时还不会受到电磁干扰的影响。

该测温仪还配备了一个显示屏,用以显示当前温度或所有仪器参数。此外,如有需要,所有参数都可通过内置键盘进行设置。温度还可通过串行接口以及所配备的InfraWin软件显示并存储在电脑中,还可对参数进行设置。

典型应用:

  • 感应加热
  • 退火
  • 焊接
  • 锻造
  • 烧结
  • 熔融
  • 轧钢厂
  • 旋转窑
  • 浇注流
  • 研发
  • 激光应用
