Tunable Diode Laser Gas Analyzers from METTLER TOLEDO
Interference-free, drift-free tunable diode laser technology offers better process control and lower maintenance costs.
However, for reliable measurement with a tunable diode laser gas analyzer, or TDL gas analyzer for short, sometimes the required framework conditions such as minimum optical path length, the availability of a purge gas supply and/or maximum dust load get in the way.
Acknowledging these constraints, METTLER TOLEDO has developed specific process interface solutions that substantially increase the coverage of possible tunable diode laser gas analysis applications.
Based on the folded optical path principle, METTLER TOLEDO’s range of compact tunable diode laser spectrometers and unique process adaptions, for process, safety, combustion, and vapor recovery applications are essential instruments for improving your processes:
METTLER TOLEDO's unique process adaptions, make it possible to use a TDL gas analyzer in applications previously considered impossible for an in situ TDL analyzer.
The GPro® 500 series of tunable diode laser gas analyzers is built on a unique folded-path design. The laser source and detector are located in a single unit on one end of the sensor, and the laser beam is reflected back by a three-sided mirror to the detector, so alignment is always perfect. With our wide array of process adaptions, the GPro 500 can be used in almost all pipes and stacks.
The GPro 500 does not require maintenance-prone extractive and conditioning systems. This means that you receive consistent performance from your tunable diode laser gas analyzer without the downtime and cost associated with these traditional systems. You achieve reliable uptime, critical in safety applications, at a reduced cost of ownership.
