Carbon Monoxide & Methane Gas Analyzer: GPro 500

TDL Analyzer for CO & CH₄ Measurement

The GPro 500 TDL carbon monoxide and methane gas analyzer is a unique TDL dual spectrometer designed for direct measurement of CO & CH₄ in combustion control applications. It uses a folded-path laser beam design
for simple installation and gas measurement.

Top Performance in Carbon monoxide and methane Measurement
A carbon monoxide and methane analyzer for challenging applications, the GPro 500 provides a reliable
measurement in process control and combustion applications.

Low Maintenance and Operating Costs
This carbon monoxide and methane 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 Combustion & Process Control Needs

This carbon monoxide and methane gas analyzer is ideal for process control in combustion applications. The GPro 500 CO gas analyzer is optimal for measurement in furnaces, fired heaters and incinerators. These TDL gas analyzers offer precise, reliable, and fast measurement.

Immediate, In Situ Measurement

The GPro 500 carbon monoxide and methane gas analyzer is installed in situ, so you get a quick response without the need to condition a sample. This offers a reliable and cost-effective alternative to technologies that require maintenance prone extraction and conditioning systems.

Designed for Challenging Installations

The GPro 500 is configurable, enabling the carbon monoxide and methane 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 Carbon monoxide and methane 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.
