TECHNICAL DATA

Precise non-contact
temperature measurement

from – 40 °C to 975 °C
(–40 °F to 1787 °F) in rough

environmental conditions

Features:

• The new infrared thermometer for hot environmental temperatures up
to 250 °C (482 °F) without any need of cooling

•

A varity of applications in dryers, ovens, heat treatment lines in the metal and glass
industry, paper, plastic and textile manufacturing and semiconductor processing in
the temperature range of –40 °C to 975 °C (–40 °F to 1787 °F) and a response time
up from 100 ms

• Selectable 10:1 or 2:1 optics, compact sensor head size

• Narrow beam optics allows oblique aiming to avoid material thickness dependent
temperature readings

• Monitor box for programming and temperature display

•

Analog outputs 0/4 – 20 mA, 0 – 5/10 V, thermocouple type K or J and integrated digital

interfaces (optional) Probus DP, USB, RS232, RS485 or CAN
