Pyrometer UPF IV

This series has been replaced by UPF V pyrometers.

Narrow-band UPF IV pyrometers serve for non-contact temperature scanning of molten and solid masses in metallurgy, forges, glassworks, coking plants, fireclay factories, hardening shops, wire works, chemical plants, engineering factories, and scientific laboratories. The temperature values can be processed by a programmable logic controller or a digital controller.

Pyrometer UPF IV(-G)

calibration certificate

When the temperature of the environment is above 65 °C or the environment is dusty, an optional pyrometer shell can be used. The cover is equipped with water cooling which protects the pyrometer from high temperature and mechanical damage.

A pyrometer calibration certificate certifies accordance with national etalons corresponding to the international system of units SI.

Notes:

When using different scanning distances that those listed, the diameter of the measuring point is always larger.
The presented reproducible accuracy applied to the upper-half of the range.

If necessary, these models can be supplied with modifications to various input voltages and/or different temperatures measuring ranges.
