1. Total Solution for Flue Gas Analyzer Series

2. Technologies & Strengths

3. NDIR Dual Beam Technology
Based on dual beam design which one is reference channel and another one is test channel,
our sensors always get reference to make immediate self-adjustment to ensure the high performance.

4. Micro-flow NDIR Technology
Dual gas chamber design innovatively, one gas cell is injected measurement gas, another one is filled with reference gas N2, then micro-flow infrared sensor output the signal change, comparison between measured gas variation and reference gas signal to get the precise measurement result.

5. UV-DOAS Technology Light source: Xenon flash lamp.
Gas chamber: Long optical path reflection gas chamber.
Spectrometer: UV-band spectral response is fast, measurement accuracy is high, resolution is good.

6. Technology Benefits Micro-flow NDIR UV DOAS
Best choice for measuring SO2, NO, CO ≥ 500ppm
Best choice for measuring SO2, N0 ≤ 500ppm, dual range H2S
Water adjustment device to eliminate the impact of on measurement
Unaffected by moisture and environmental temperature
Integrated temperature controller to reduce environmental temperature affect
Drift is less during ultra-low range measurement
Less drift & stable performance
Minor vibration impact
