GPro - Model 500 -Moisture Sensor

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

• Effective path length:
• Probes: 100, 200, 400 mm (3.94", 7.87", 15.75")
