Moisture & Water Vapor Sensor: GPro 500
Tunable Diode Laser for H₂O Measurement
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.
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
|Protect Your Assets from Corrosion|
The GPro 500 moisture and water vapor analyzer is ideal for corrosion prevention at chlorine compressors. By detecting water vapor at ppm levels, you can control corrosive moisture in your gas stream. These TDL analyzers offer fast water vapor measurement.
|Immediate, In Situ Measurement|
This H2O analyzer is installed in situ, so you get a quick response without the need to extract and condition a sample. This offers a reliable and cost-effective alternative to technologies that require extraction and conditioning of the gas stream.
|Designed for Challenging Installations|
The GPro 500 is configurable, enabling the moisture and water vapor gas analyzer's measurement system to be paired with a variety of process adaptions to meet a wide range of installation requirements and pipe sizes.
|Predictive Diagnostics Ensure Long Life|
This moisture 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.
