Controlling the level of gaseous oxygen in your process is key to ensuring the safety of the environment, people and your assets. Equally important, processes involving oxygen as a reactant must be carefully controlled to remain within safety limits. Based on our long-standing field experience in analytical measurement solutions for liquids, we have developed Tunable Diode Laser (TDL) spectrometer systems for in situ, real-time measurement of oxygen and other gases.
In situ measurement: Our systems are built to be installed in-line, exactly where you need to measure.
Low cost of ownership: Outstanding measurement performance without the drawback of heavy maintenance.
Rugged design: Long-term reliability for continuous use in the harshest environments.
Tunable Diode Laser gas spectrometers work by using a laser diode that emits light at a specific wavelength that can be finely tuned to scan an absorption line of a target gas. As the laser light passes through a gas sample, the gas molecules absorb light at certain wavelengths. By measuring the intensity of the light absorption, the spectrometer can determine the concentration of the target gas.
The GPro 500 provides precise and consistent gas analysis results, ensuring reliable data for process control and quality assurance.
The sensors are built to withstand harsh industrial environments and offers long-term stability and reduced maintenance needs.
GPro 500 delivers almost instant measurement of gas concentrations, enabling timely decision-making in critical applications.
Adaptable design allows it the sensors to be tailored for use in a wide variety of applications, accommodating different gases and measurement conditions to meet specific industry needs.

The GPro 500 TDL analyzer offers adaptions to fit your process needs. Designs fit in pipes as small as DN50 (2"), and can measure accurately in high-dust, high-condensate and blanketing applications.
The METTLER TOLEDO TDL analyzer is built on a unique folded-path design, the laser source and detector are located in a single unit to perfectly reflect the laser beam to the detector.
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.
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 analyzers offer a robust construction, allowing the system to be immune to interference and suitable for the most challenging and critical applications.
These tunable diode laser gas analyzers can provide a measurement in less than 2 seconds. This allows users to take quick actions to mitigate explosive conditions from forming.
METTLER TOLEDO TDL spectrometers can measure oxygen, carbon monoxide, carbon dioxide, moisture, hydrogen sulfide, hydrogen chloride, ammonia and methane.
Rethinking Gas Analytics Across Process Industries. Plant safety, product quality, high productivity: that’s what’s most important to you.
This brochure is designed to help safety engineers understand the important considerations required when selecting a gas analyzer for process safety applications. It focuses on evaluating risks in your specific applications, and then ensuring safe analyzer implementation and long-term operation.
Selecting analyzers can be a tricky process, so a gas analyzer guide can be very useful. Having the right gas analyzer doesn’t just determine your process safety and efficiency, it can effect maintenance work and have an impact on the environment.
In chemical plants, petrochemical plants, and refineries tunable diode lasers (TDLs) are becoming an increasingly common sight. Their high reliability and low maintenance has made them the gas analyzer technology of choice for many companies.
In the chemical industry, safety during gas measurement is of the highest priority. Choosing the right measurement equipment is a challenge many companies face.
Since their first use in the 1990s, Tunable Diode Laser gas analyzers have seen rapid growth in industry due to their exceptional performance and reliability.
