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.
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.
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.
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.
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.
