Description
Overview
GAOTek multi-gas analyser is designed to measure CH4, CO2, O2, H2S and optional H2, CO gases in biogas. This model is powered by a lithium battery and with a very compact design that is very suitable for remote use onsite. Its modular sensor design ensures easy operation and maintenance. It is very suitable for research purposes or daily inspection in different biogas applications such as Anaerobic Digestion, landfill, wastewater treatment, biomethane and so on.
Features
- Modular NDIR and ECD sensors design for easy maintenance
- facilitating easy transportation between different sites
- Auto temperature compensation to ensure precision in measurements
- Precision filters to effectively remove moisture
- dust from the sample gas, providing analyser protection
- Rechargeable Lithium battery that supports up to 8 hour
- In-built memory capable of storing up to 2560 units of records
- simplifying data download to a PC.
