Oxygen Gas Analyzer: GPro 500
Tunable Diode Laser for O₂ Measurement
The GPro® 500 oxygen gas analyzer is a unique tunable diode laser spectrometer designed for safety applications. It uses a folded-path laser beam design for simple installation and measurement.
Fast Response In Safety Applications
An oxygen gas analyzer for safety applications, the GPro 500 provides a fast response time in combustion control and inerting applications.
Low Maintenance and Operating Costs
This oxygen gas analyzer is designed to operate in situ without a maintenance-prone conditioning system, reducing the total cost of ownership.
Easy Installation
The GPro 500 is an alignment-free TDL gas analyzer, meaning that the typical challenges of TDL installation and alignment are significantly reduced.

Features and Benefits
| Meets Critical Application Needs This oxygen gas analyzer is ideal for applications such as: flare safety control, combustion control, chlorination and oxychlorination, process control, ESP filter production, vent headers, inertization and vapor recovery. |  |
| Immediate, In Situ Measurement The GPro 500 oxygen gas analyzer is installed in situ, so you get a quick response without the need to extract and condition a sample. This provides a fast response time so that you can make real-time reactions to out-of-spec conditions. |  |
| Designed for Challenging Installations The GPro 500 is configurable, enabling the oxygen gas analyzer's measurement system to be paired with a variety of process adaptions to meet a wide range of installation requirements. |  |
| Predictive Diagnostics Ensure Long Life This oxygen gas analyzer uses Intelligent Sensor Management (ISM®) technology to offer predictive diagnostics on analyzer condition, including informing you when cleaning of the optical path will be required. |  |
