Optris CTLaser LT, Double laser spot pyrometer with temperature range [-50 .. 975°C]

The infrared thermometer Optris CTlaser LT allows for exact temperature measurement on smallest objects from 0,9 mm at a distance of 70 mm (CF1). 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. Additionally, it offers a high variability due to selectable analog outputs as well as several digital interfaces in the electronics box.

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.

Features:

• Large temperature range: -50°C to +975°C
• Rugged and usable up to +85°C ambient temperature without cooling
• Separate electronics with easy accessible programming keys and LCD backlit display
• Selectable analog output: 0/4-20 mA, 0-5 V, 0-10 V, thermocouple type K or J
