Overview
KSA-2000P is a portable biogas analyzer that simultaneously measures five gas components: CH4, CO2, H2S, O2 and H2.
It features a 5-inch color touch screen, online gas concentration monitoring, 4~20 mA analog output, measurement data storage, and gas concentration alarms with alarm relay output.
With a modular design for easy calibration and a rugged portable build, it is well suited to on-site measurement at biogas production and treatment facilities such as anaerobic digesters, biogas engines/CHP and H2S scrubbers.
