和IGA 50-LO plus是数字式、高精度测温仪，配备了光纤镜头，用于非接触式测量金属、石墨、陶瓷等物体，测温范围250-2500 °C。
IS 50/67-LO plus是一款特殊的测温仪，其波长极短，用于测量具有很高辐射率的熔融金属的温度。该仪器配备了一根光纤以及一个光纤测头，不受电磁干扰（如：感应）的影响，最高耐温可达250 °C。
根据不同的测量距离，两个不同的测头可供选择，可实现极小的光斑尺寸。激光靶光可以用来瞄准测量物体。响应时间小于1毫秒，可实现快速加热过程的测量。该测温仪还配备了一个显示屏，用以显示测量模式下的当前温度。此外，所有通过仪器上的集成键盘进行设置的参数都可在屏幕上读取。
温度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：
- 金属模具
- 冲压工具
- 轴承、轴承外壳
- 预热
- 退火
- 回火
- 烧结
- 锡焊
- 轧钢
- 铜焊
- 正火
