Rethinking Gas Analytics: Analyser Series Extension Launched

Mettler Toledo Process Analytics (USA) is proud to announce the global release of its most significant line expansion since the launch of the GPro 500 O2 gas analyser in 2012. Building upon the unique probe concept, new process adaptions are available to enable the deployment of Tunable Diode Laser (TDL) technology in measurement locations never previously possible. Further, Mettler Toledo now makes full use of the platform concept of the GPro 500 Series by introducing CO and moisture spectrometers that are freely selectable with any suitable process adaption.

Measure everywhere it matters in your process

For reliable measurement with a TDL, sometimes necessary framework conditions such as minimum optical path length, availability of purge gas supply and/or maximum dust load get in the way of users that are keen to reap the benefits of the interference-free, drift-free TDL technology for better process control and lower maintenance costs. Acknowledging these constraints, Mettler Toledo has developed specific process interface solutions to substantially increase the coverage of possible TDL applications by thinking out-of-the box, to create innovative adaptions. For example, the wafer cell adaptor allow direct cross-section installation down to DN50 (2”) diameter pipes with no flow restriction and minimum additional pipe work required. Further, static process gas conditions are no longer an obstacle for a GPro 500 installation with the process purge-free probe for inertisation and blanketing applications. Finally, the new purge-free filter probe is ideal for the measurement in high-dust applications where cross-stack type TDLs typically require high optical purge flows and can be problematic due to the loss of signal intensity.

New gases, new opportunities for combustion applications

Compact, explosion-proof spectrophotometers with advanced SpectraID signal processing are the hallmark of the GPro 500’s design. The analyser’s ruggedness and small footprint allow installation in the most difficult locations. With the availability of reliable CO TDLs for installation in combustion on fired heaters, package boilers and similar power applications, users can now switch from oxygen-only, fixed-point control to combined oxygen and CO trim control.  This can significantly reduce fuel costs and NOx emissions.
