Description

The WiMo Plus Multi-Parameter Logger can be fitted with up to 7 probes to monitor a wide range of water parameter. The unit has a magnetically activated WiFi interface that allows simple configuration with a mobile or tablet using a web browser and the internal web interface. The WiMo Plus automatically detect the connected sensors and allow you to select the ones you want to log and show any available calculated parameters available that you can also log. The WiMo Plus can log the readings internally for later retrieval, provide a Modbus RTU output, or connect to a 3G/4G transmission module that can send the data via a mobile network, this can be via the Starlink network for remote location out of reach of onshore mobile masts.

The WiMo Plus is the larger model in the range, including a smart cleaning system that can fit to the central sensor port to ensure the six other probes are kept clean of any debris. The rotating arm cleans the top of each of the installed probes. This can also ensure the sensors are clear of air bubbles and any bio-fouling common with any extended deployments. Any other sensors can be fitted to remaining six empty ports. Available sensors are designed to be fully submerged in water and rated for depth up to 250m.
