Methane Gas Analyzer: GPro 500
Tunable Diode Laser for CH4 Measurement
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.
