The LS4000 is an in situ cross-duct analyzer for measuring gas component concentrations.

It applies the highly selective, optical measuring principle of tunable diode laser (TDL)

absorption spectroscopy.

The LS4000 is a stand-alone system and is approved for use in hazardous areas according

to international standards. The device consists of a transmitter unit with a laser light source and a receiver

unit with a photodetector. The two units are mounted opposite each other on the process pipe or stack

and are connected by a junction box.

The advantages to you:

High precision

Due to the narrow spectral width of the laser beam and the narrow scan window, only the absorption by

the target gas component is measured. Consequently, high selectivity and accuracy are achieved and the

measurement is virtually cross-interference free.

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.
