Overview

KSA-2500A is an online biogas analyzer that simultaneously measures and continuously monitors four gas components: CH4, CO2, H2S and O2.

It has an H2S measurement module with automatic air purge, automatic condensate drain and full built-in diagnostics, and displays real-time data on a 7-inch touch screen.

Housed in an IP54 wall-mounted industrial enclosure, it is used for continuous monitoring at biogas production facilities and for quality and process control of biogas upgrading.
