TECHNICAL DATA

Precise focussing and non-
contact temperature measure-
ment from –50 °C to 975 °C
(–58 °F to 1787 °F)

Features:

• Low and high temperature measurements of smallest spots up from 0.9 mm
(0.04 in)

•

Double laser aiming marks real spot location and spot size at any distance

• Optics 75:1 and 50:1 with selectable focus

• CT laser F (fast) for scanning of fast moving low temperature objects up from
9 ms response time

• Usable up to 85 °C (185 °F) ambient temperature without cooling and

automatic laser switch o󰀨 at 50 °C (122 °F)

• Selectable analog outputs 0/4 – 20 mA, 0 – 5/ 10 V, thermocouple type K or J

• Optional plug in digital interfaces USB, RS232, RS485, CAN or Probus DP
