Online NDIR Infrared Biogas Analyzer For CH4 ,CO2 ,H2S and O2
Part No: INGA-13004
Used for measurement of the concentration of CH4 ,CO2 ,H2S and O2 in sample gases simultaneously . It is based on the single source two beams non-dispersion infrared (NDIR) method for CH4 ,CO2 ,fuel cell method (ECD) for H2S and O2.
Application:
Landfill, water treatment, CDM project ,anaerobic digestion and other fermentation processes
Features:
1. Up to 4 gases measurement with combination of NDIR and ECD gas sensor technology.
2. Simple construction with pulsable infrared source and two beams technology.
3. Constant temperature control for gas bench for high stability.
4. 320*240 LCD with menu operation.
5. Repeatability:±0.5% FS.
6. Linearity: ±1% FS.
7. Zero/Span drift: ±2%FS
