METTLER TOLEDO TDL analyzers offer a series of process adaptions to give you a range of options to measure in situ, extractive or in cross-pipe installations. All tunable diode laser analyzers, or TDL analyzers for short, from METTLER TOLEDO require no alignment, and the standard probe-type analyzers fits in pipes down to DN100 (4"). Other adaptions include a TDL analyzer designed for DN50-sized small pipes (2"), a filter probe for high-dust or high-condensate applications and a non-purge probe for blanketing applications.

Tunable Diode Laser Gas Analyzers from METTLER TOLEDO

Measure Where it Matters

Eliminate the Need for Alignment
The GPro® 500 series of tunable diode laser spectrometers is built on a unique folded-path design. With the laser source and detector located in a single unit on one end of the sensor, the laser beam is reflected back by a three-sided mirror to the detector, offering perfect alignment. With our wide array of process adaptions, the GPro 500 TDL analyzer can be used in almost all pipes and stacks.
One Unique, Versatile Instrumentation Platform
Using a modular design, the GPro 500 tunable diode laser analyzer allows you to select the process adaption that fits your application, and match it with the parameter that you need to measure. In addition to a TDL oxygen analyzer, 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) and Methane (CH₄).

Tangible Performance, Minimal Maintenance
The GPro 500 TDL spectrometer does not require maintenance-prone sampling and conditioning systems. This means that you receive consistent performance from your tunable diode laser 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.
