Methods of in-situ continuous process gas analytics

Put us to the test

In-situ analytical procedures feature physical measurements in the flow of a process gas, directly in the actual process gas line. In contrast to extractive gas analysis, a sample is not taken and routed onto the analyzer via a sample line and sample conditioning.

In-situ Continuous Process Gas Analytics

In-process gas analysis

SITRANS SL and LDS 6 reference cells

Operating software

LDSComm – the software tool for remote diagnostics and maintenance

The LDSComm software tool for continuous, in-situ process gas analytics offers you clear menu navigation and extensive user support.

Manage everything with one operator interface

The LDS 6 can be operated remotely via the Ethernet port with a PC running Windows 95/98/ME or Windows NT/2000/XP. It‘s also possible to connect the LDS 6 to the public telephone network via a modem. This requires an LDS 6 LAN modem kit. Any external connection requires that the optional LDSComm (LDS Communication Client) software be installed on the remote computer, thereby making it possible to control all LDS 6 functions.
