Hydrogen Sulfide Gas Analyzer: GPro 500

Hydrogen Sulfide Gas Analyzer: GPro 500

Tunable Diode Laser for H2S Measurement

The GPro 500 hydrogen sulfide (H2S) gas analyzer is a unique tunable diode laser spectrometer designed for direct measurement of H2S in gas streams. It uses a folded-path laser beam design for simple installation and accurate H2S measurement.

Top Performance in H2S Measurement
An H2S analyzer for challenging applications, the GPro 500 provides a reliable measurement in catalytic reformers and coke oven gas measurements.

Low Maintenance and Operating Costs
This H2S 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.
