Description

Performance, precision and reliability – you can count on MAURER pyrometers. The compact and easy to use design, as well as a large selection of matching accessories, enables you to quickly integrate the pyrometer into your surroundings.

The most important features and characteristics at a glance:

Spectral range: 0,85 – 1,1 µm
Short responsetime of 1 ms, with dynamic adjustment
Emissivity slope from 0,8 – 1,2, adjustable directly at the pyrometer or via interface
Green target light (LED) that is exactly identical to the actual measuring spot in position and size
With fiber optic cable and optic system for exact focusing even in narrow spaces
Use with either digital and analogue output
1 limit output (open collector)
Operating voltage 24 V DC
Free software (IR-LOG) for parameter setting, data recording and storage

Scope of Applications
Processing of steel, iron, non-ferrous metal and wires, ceramics, glass tub, glass arching, as well as hardening, rolling, soldering, forging, welding, transforming, induction heating, vacuum furnace, etc.
