Introduction
Gasboard-3200L portable biogas analyzer is designed to measure CH4, CO2, H2S and O2 concentration simultaneously in different biogas applications, like landfill, water treatment, CDM projects, anaerobic digestion and other fermentation processes, based on NDIR technology for CH4, CO2 gases, ECD technology for H2S and O2 gases. This model can be powered by lithium battery ensure easy carrying among different measuring points
Applications
Biogas plants
Anaerobic digestion
Waste water treatment plants
Sludge digestion
Biomethane production plants
Landfill sites
Features
1. Measures CO2, CH4, O2, H2S gases with customized measure range
2. Modular sensor design ensures easy on operation and maintenance
3. Self-developed gas conditioning device to remove vapor and dust in biogas for analyzer’s protection in long term operation
4. Built in rechargeable lithium battery for easy carrying
5. Stores and downloads readings available.
