General Specifications

Temperature range 0°C ... 900°C
Temperature resolution (NETD) Depends on measuring temperature and response time, typical value 0.2°C (at 300 ms, 100 °C, e = 1)
Accuracy (uncertainty) ± 0.8°C plus 0.8% of the difference between target and sensor head temperature
Long term stability Better than 0.01% of the absolute measured temperature per month
Field of view diameter From Ø 1 mm, depending on lens
Field of view marking Laser pointer as accessory for non transparent lenses
Pilot laser, built-in: aims the center of the field of view in any distance
