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
