TECHNICAL DATA

Non-contact
temperature measurement
through ames from
200 °C to 1650 °C

Features:

• Accurate temperature measurement through ames in the range from
200 °C to 1650 °C (392 °F to 2912 °F) to monitor workpieces inside ovens (heated
with re), to measure inside chemical reactors and to observe the brick
temperature in combustion chambers

• Double laser aiming marks real spot location and spot size up from 1.6 mm
(0.06 in) at any distance

• Optics 45:1 with selectable focus, compact sensor head size

• Usable up to 85 °C (185 °F) ambient temperature without cooling and automatic
laser switch o󰀨 at 50 °C (122 °F)

• Cooling and protection accessories for harsh environmental conditions
