Direct measurements in the gas stream

The GPro 500 Moisture TDL allows drift-free, virtually maintenance-free operation in dry storage applications by allowing the measurement of water vapor at ppm levels to protect your assets from corrosion damage in applications including: 

Process control
Cl2 storage
EDC storage
Features and Benefits

Tunable Diode Laser spectroscopy

Dependable, industry-proven technology

Simple installation

Thanks to probe design and single flange connection

In situ measurement

Direct measurements in the gas stream are fast and reliable

SpectraID technology

For highly reliable O2 measurement

Low cost of ownership

No sampling or conditioning equipment. Annual verification and periodic optics cleaning are the only maintenance

Low nitrogen purging consumption

For lower operation costs

Predictive ISM diagnostics

Continually monitor optical path quality to determine when cleaning will be required
