Multilog 2 WW

Built to withstand the corrosive conditions encountered within waste water environments, Multilog 2 WW is specifically designed to be compatible with a wide variety of third-party sensors, including RavenEye, MicroFlow-i, dBi and VEGAPULS.

Including four sensor connections and delivering up to 8 logging channels, Multilog 2 WW is highly versatile and is suitable for a wide array of applications, including depth, flow and quality data logging, battery telemetry for third party radar depth and velocity sensors and Modbus sensor telemetry.

Designed specifically for non-ATEX applications, Multilog 2 WW is housed in a drop tested non-metallic casing and has non-metallic connectors to prevent against corrosion in harsh environments.


A highly-compatible, self-powered data logger that benefits from our advanced modem for dependable connectivity, Multilog 2 WW is the ideal solution for non-ATEX environmental and waste water monitoring.
