The trace water analyzer adopts advanced laser modulated spectroscopic absorption technology. Its measurement results are free from interference by background gas media. It achieves a limit of detection down to 1 ppb and supports dual-range configuration. Developed specifically for trace moisture impurity detection in high-purity, ultra-pure and ultra-high-purity electronic specialty gases, the analyzer features a passivated gas cell and gas path design. Its unique chamber structure enables fast response. It is especially suitable for moisture measurement in highly corrosive gases, free from interference from other gases. It requires minimal maintenance and supports remote control, ideal for industrial process monitoring, atmospheric environment monitoring, medical applications and other fields.

Features

• Advanced Technology: Adopts TDLAS technology with a highly stable tunable laser diode.

• Strong Anti-interference Capability: Exclusive technology eliminates interference from various gas molecules, enabling direct measurement without gas dilution.

• Stable Performance: Peak-locking technology precisely locates the moisture spectral peak for repeatable baseline measurement, unaffected by mirror reflection loss.

• Flexible Application: Supports both online and laboratory measurement modes to meet trace moisture testing requirements in diverse scenarios, such as moisture detection in ammonia gas.

• Cost Advantage: Modular design allows individual on-site component replacement. The built-in solid-state drive can store five years of test data, and the analyzer has no consumables.
