In-situ TDLS

In-situ analytical procedures feature physical measurements in the flow of process gas directly in the actual process gas line. In contrast to extractive gas analysis, a sample is not taken and routed on to the analyzer via a sample line and sample preparation. The fast and non-contact measurement of gas concentrations directly in the process is the domain of in-situ diode laser gas analyzers (TDLS – Tuneable Diodelaser Spectroscopy).

Gas analyzer for 1-3 measuring points: LDS 6

The gas analyzer LDS 6 combines the compact and service-friendly design, simple operation and network capability of the Series 6 analyzers with the well-known exceptional performance data of in-situ gas analysis - namely high ruggedness and availability as well as low maintenance - by using diode laser technology and fiber-optics. Up to three LDS 6 in-situ cross-duct sensors (which are also optionally available in an intrinsically-safe version for operation in hazardous areas) can be combined with an analyzer in the compact 19" rack unit enclosure.

Compact acid and carbon monoxide analyzer for individual measuring stations: SITRANS SL

The SITRANS SL gas analyzer for measurement of oxygen and carbon monoxide has a more integrated design without fiber-optic cables and with only one pair of cross-ducts sensors, a transmitter unit, and a detector unit. In this case the receiver has a local user interface (LUI) which is controlled using IR remote control.
