Tunable Diode Laser (TDL) Gas Analyzers

A series of process adaptions gives you a range of options to measure in situ, extractive or in cross-pipe installations. All tunable diode laser gas analyzers from METTLER TOLEDO require no alignment, and the standard probe-type analyzers fits in pipes down to DN100 (4").

Other adaptions include designs for DN50-sized small pipes (2"), a filter probe for high-dust or high-condensate applications and a non-purge probe for blanketing applications.

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.

Using a modular design, the GPro 500 tunable diode laser gas analyzer allows you to select the process adaption that fits your application, and match it with the parameter that you need to measure.

We offer sensors that measure  a variety of gases including Carbon Dioxide (CO₂), Carbon Monoxide (CO), Hydrogen Chloride (HCl), Hydrogen Sulfide (H₂S), Moisture, Ammonia (NH₃), Methane (CH₄) and Oxygen (O₂).

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.
