The GPro 500 carbon monoxide percent gas analyzer is a unique tunable diode laser spectrometer designed for measurement of CO in a gas stream at high temperatures. It uses a folded-path laser beam design for simple installation and CO% measurement.
Top Performance in CO% Measurement
A CO% analyzer for challenging applications, the GPro 500 provides reliable measurement in FCC units, PTA, steam reforming, and hydrogen production.
Low Maintenance and Operating Costs
This CO% gas analyzer is designed to operate at high temperatures, in situ without a 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.
