CT 1M/2M

TECHNICAL DATA

Precise non-contact
temperature measurement
from 250 °C to 2200 °C
(483 °F to 3992 °F)

Features:

• 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 (0.6 in) diameter and 28 mm (1.1 in) length
ts everywhere and is usable up to 125 °C (257 °F) ambient temperature
without cooling

• Temperature ranges from 250 °C to 2200 °C (483 °F to 3992 °F), measuring
spots up from 1.8 mm (0.07 in) 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
