TDL Process Adaptions for the GPro 500
Accurate Measurement in All Process Conditions
Tunable diode laser process adaptions allow the integration of a GPro 500 TDL spectrometer directly into a process gas stream for in situ measurement, or in an extractive cell. These TDL process adaptions are suited to a range of environments, including fast or slow moving gas streams, dirty gas streams and narrow pipes (down to DN50 or 2" pipes). These process adaptions use folded-path TDL spectroscopy to provide an accurate measurement without the need for alignment of a receiver.

TDL Analyzer to Fit Your Process Needs
The GPro 500 TDL process adaptions allow the gas analyzer to fit in pipes as small as DN50 (2") and help measure accurately in high-dust, high-condensate and blanketing applications.
Eliminate the Need for Alignment
These process adaptions support the GPro 500's unique folded-path design: the laser source and detector are located in a single unit to perfectly reflect the laser beam to the detector.
Configure for Your Specific Requirements
The GPro 500 TDL analyzer offers a modular design, allowing you to select the process adaption that best fits your application, and match it with the gas parameter that you need to measure.
Minimal Maintenance Required
With maintenance-prone sampling and conditioning systems not required, these tunable diode laser analyzers provide consistent performance, with maintenance needed only once per year.
TDL Spectrometer Built for Challenging Applications
TDL analyzers offer a robust construction, allowing the system to be immune to interference and suitable for the most challenging and critical applications.
Wide Range of Measurement Parameters
METTLER TOLEDO TDL spectrometers can measure oxygen, carbon monoxide, carbon dioxide, moisture, hydrogen sulfide, hydrogen chloride, ammonia and methane.

FAQs
What is a Tunable Diode Laser process adaption?
Tunable diode laser process adaptions are a key component of a GPro 500 gas analyzer. They connect the spectrometer to the process for accurate measurement of the specified gas species. They facilitate the folded-path TDL technology of the GPro 500, reflecting the laser back to the receiver.
What types of TDL process adaptions are available?
METTLER TOLEDO offers several different TDL process adaptions to meet unique application requirements. Examples include:
- The wafer TDL process adaption: designed to provide accurate measurement in small line sizes, down to DN50 (2") pipes.
- The non-purged probe with filter and blow-back process adaption: optimal for dry gases with particulate, such as flue gases.
- The standard purged probe: for in situ measurement in near-saturated gas streams, such as a combined vent line to a destruct unit.
- The cross-pipe: optimal for pipes from 1-3 meters in diameter and hot gas streams.
What gas species can be measured with a TDL analyzer?
METTLER TOLEDO GPro 500 TDL analyzers offer measurement of carbon monoxide (CO%), carbon dioxide (CO2%), hydrogen chloride (HCl), hydrogen sulfide (H2S), gaseous oxygen (O2), methane, ammonia and moisture. These can be paired with a wide range of process adaptions to provide the tunable diode laser analyzer to meet your requirements. For example, an oxygen gas analyzer can be paired with a filter probe to allow you to install an oxygen TDL analyzer in a gas stream that has a heavy particulate content. That same oxygen gas analyzer can be paired with a wafer adaption to create an in-line TDL gas analyzer for oxygen in a small line size (down to DN50).
