Suitable for harsh process conditions

LS4000 applies a non-contact, optical technique, which allows the measurement of corrosive, toxic and

hazardous gas streams directly in the process. The laser analyzer is suitable for measurements at elevated

temperatures up to 1500 °C (2732 °F) and pressures up to 20 bar (290 psi).

The influence of temperature and pressure variations is eliminated by automatic dynamic correction.

Fast and direct

A sampling and conditioning system is unnecessary since the instrument is directly installed on the

process (in situ).

This results in a typical response time of 2 seconds, providing better loop control and faster detection of

critical conditions.

The in situ laser analyzer is ideally suited for process optimization and safety measurements.

Safe, compact and easy

− No purging for installations in hazardous areas – the analyzer includes flameproof housing (Ex-d) with

international certifications

− No nitrogen purging of the analyzer housing for O2 measurement

− Insensitive to vibrations through compact and lightweight design

− Ease of maintenance
