Fixed biogas analyzer
Description: An explosion-proof biogas analyzer (online infrared gas analyzer) is used to accurately measure the concentration of CH4, CO2, and H2S in biogas of large and medium-sized biogas projects. Equipped with a patented H2S life protection device, a maintenance-free biogas pretreatment device, an automatic temperature control device, a high protection level,
stable working performance, long service life, very suitable for high moisture and high H2S content biogas metering. It is used to analyze the concentration of CO2, CH4, H2S and other gases in process pipelines so that field personnel can understand the gas conditions in the pipeline, and it is a reference for mentioning production efficiency and production safety monitoring.

Portable infrared biogas analyzer
The portable infrared biogas analyzer adopts the most advanced NDIR non-spectrographic infrared and ECD long-life
electrochemical technology, and is mainly used to measure the volume concentration of CH4, H2S, CO2 and O2 in biogas.
The product has high measurement accuracy, simple structure, convenient operation and good practicability.
Scope of application: It is suitable for landfill, sewage treatment, anaerobic fermentation production process and
CDM measurement and other application fields, as well as the monitoring of CH4, H2S, CO2, O2 and other gas components
in scientific research laboratories.
While continuing the advantages of the previous generation of products such as high precision and no consumables,
the volume is reduced by 75% and the weight is reduced by 60%.
Product Features
1. Portable body design
It is easy to carry and can meet the needs of industrial field measurement and laboratory air bag sampling analysis
at the same time.
2. High measurement accuracy
Modular design of the sensor, simultaneous online measurement of the volume concentration of CH4, CO2, H2S, O2 and
other gases.
3. Stable performance
The sensor adopts a dual-channel design, with strong stability; it has a self-diagnosis function, which can check the
sensor status online.
4. Power can only be managed
Configure the soft-start power switch, and the battery power can only be managed to avoid the instrument working under
low power conditions.
5. Convenient data management
Automatically store measurement data, with query and delete functions, and can be transmitted to the upper-level
centralized control system through various interfaces.
6. Low cost of use
Compared with gas analysis technologies such as Austrian style and chromatography, the measurement process does not
require disassembly, installation, consumption of chemical reagents, etc., and the operation is simple and no consumables are required.
7. Gas flow rate can be collected (hand-held flow meter is required)
8. With Bluetooth function, it can upload the collected data and display it on the APP
9. With GPS positioning function
