The GPro 500 moisture and water vapor (H2O) analyzer is a unique tunable diode laser spectrometer designed for direct measurement of H2O in gas streams. It uses a folded-path laser beam design for simple installation and accurate moisture detection.
Top Performance for Moisture Measurement
A moisture sensor for challenging applications, the GPro 500 provides a reliable measurement in applications such as chlorine gas and EDC storage.
Low Maintenance and Operating Costs
This H2O 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.
