The infrared thermometer optris CTlaser LT allows for exact temperature measurement on smallest objects from 0,9 mm at a distance of 70 mm.
The IR thermometer optris CTlaser LTF is due to its short configuration time of only 9 ms perfectly suited for surveillance of quick working processes. Both models offer a robust and premium-quality stainless steel measuring head with an innovative double laser sighting for an exact measuring field marking in every distance.
