TECHNICAL DATA

Non-contact temperature
measurement with precise
aiming from 50 °C to 1800 °C

Features:

• Accurate temperature measurements of metals, secondary metal processing
and ceramic materials

• Double laser aiming marks real spot location at any distance

• Optical resolution up to 300:1 with selectable focus

• Temperature ranges from 50 °C to 1800 °C, with selectable focus Temperature
ranges from 50 °C to 1800 °C, measuring spots up from 0.7 mm and response
times up from 1 ms

• Usable up to 85 °C ambient temperature without cooling

• Short measuring wave length of 2.3 μm reduces error of temperature readings
on surfaces with low or unknown emissivity
