Online Infrared Biogas Analyzer For CH4 ,CO2 ,H2S and O2

   Used for measurement of the concentration of CH_{4 ,}CO_{2 ,}H₂S and O₂  in sample gases simultaneously . It is based on the single source two beams non-dispersion infrared (NDIR) method for CH_{4 ,}CO_{2 ,}fuel cell method (ECD) for H₂S and O₂.

    Landfill, water treatment, CDM project ,anaerobic digestion and other fermentation processes

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
