Methane Gas Analyzer: GPro 500

The GPro 500 methane (CH₄) gas analyzer is a unique TDL spectrometer designed for direct measurement of methane in syngas and select natural gas measurement applications. It uses a folded-path laser beam design for low maintenance measurement.

Top Performance in Methane Measurement
A CH₄ analyzer for challenging applications, the GPro 500 provides reliable measurement in syngas and natural gas measurement applications.

Low Maintenance and Operating Costs
This 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 Process Control Needs

This CH4 gas analyzer is ideal for process control in syngas applications. The GPro 500 methane gas analyzer is a tunable diode laser gas analyzer that offers precise, reliable and fast measurement in critical applications, and is SIL 2 compatible.

Immediate, In Situ Measurement

The GPro 500 CH4 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 methane gas analyzer's measurement system to be paired with a variety of process adaptions to meet a wide range of installation requirements, including pipe diameters from 50 mm to over a meter.

Predictive Diagnostics Ensure Long Life

This methane TDL 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.
