IS 50-LO plus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。
