General Specifications
Environmental rating
Ambient temperature

Miniaturized Infrared Thermometer with 1.0 µm
respectively 1.6 µm wave length range for
measurements of metals, of secondary metal
processing, metal oxides and ceramic materials
Very small sensing head of 14 mm diameter and
28 mm length fits everywhere and is usable up to
125°C ambient temperature without cooling
Temperature ranges from 250°C to 2200°C,
measuring spots up from 1.8 mm and exposure
times up from 1 ms
Short measuring wave length of 1.0 µm
respectively 1.6 µm reduces error of temperature
readings on surfaces with low or unknown
emissivity
