TDL (Tunable Diode Laser) Gas Analyzers
Rethinking gas analytics
Interference-free, drift-free TDL technology offers better process control and lower maintenance costs.
However, for reliable measurement with a TDL sometimes necessary 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 TDL applications. Based on the folded optical path principle, METTLER TOLEDO’s range of compact TDL spectrometers and unique process adaptions, for process, safety, combustion, and vapor recovery applications are essential instruments for improving your processes:
No need for alignment:
With laser source and detectors on the same side, the GPro 500 standard (SP) probe does not need alignment, and fits in pipes down to DN100 (4”).
For inerting and blanketing applications:
With its probe specially designed for static process conditions the GPro 500 with NP probe allows reliable inertization control for increased safety and lower purge gas consumption.
Measurement location in small pipes:
For DN 50 or 2” pipes where no flow restriction is allowed, the GPro 500 Wafer Cell allows precise and stable measurements even in harsh process gas streams.
Ideal for combustion applications:
Where very high dust loads will typically obstruct measurement on longer optical paths, the GPro 500 with a Filter probe enables robust measurement in fired heaters and boilers.
Compatible with existing extractive solutions:
If an extractive analyzer is already fitted, shorter response times and lower maintenance costs can be obtained by retrofitting the GPro 500 with an Extractive Cell adaption into your current sampling and conditioning system
