Optris CTlaser 3M Specifications

optris® CTlaser 3M

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 100:1 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
