Positive Pressure Explosion-proof Laser Gas Analysis System for High Precision H2S Online Monitoring with Multi-point Sampling

The AG-TDGA-7000 positive pressure explosion-proof laser gas analysis system perfectly combines Tunable Diode Laser Absorption Spectroscopy (TDLAS) and Multi Reflection Long Path Technology to improve detection sensitivity and provide the best solution for online monitoring of hydrogen sulfide.

• High precision: The optical path can reach 30 meters, greatly improving measurement accuracy and lower limit of measurement.
• No drift: A unique peak tracking algorithm that performs real-time correction at each cycle of concentration calculation, avoiding wavelength drift.
• Adaptable to harsh working conditions: High-temperature extraction pretreatment, full process high-temperature heat tracing without cold points, unaffected by harsh working conditions such as high temperature, high humidity, high dust, and flue vibration of flue gas.
• Measurement is more representative: Achieving multi-point sampling, grid sampling, multi-channel sampling, and multi-point rotating measurement, multi-point mixed measurement, multi-channel simultaneous measurement, grid measurement.
