12 thermoMETER CT laser M1/M2: Temperature sensor with laser aiming for metals

thermoMETER CT laser M1/M2 Innovative temperature sensor with laser aiming for metal processing
Measuring range from 250°C to 1800°C Accurate temperature measurements of metals, secondary metal processing and ceramic materials Short measuring wave length of 1μm or 1.6μm reduces error of temperature readings on surfaces

with low or unknown emissivity
Double laser aiming marks real spot location at any distance Optical resolution up to 300:1 with selectable focus Up to 85°C ambient temperature without cooling and automatic laser switch off at 50°C Selectable analogue outputs, optional plug in digital interfaces
