EM-2Q

EM-2Q is a purpose-built wireless water quality monitoring solution for rivers, lakes, reservoirs and coastal waters, aimed at environmental agencies, utilities and industrial operators and at regulatory requirements such as the UK Environment Act 2021. A fully submerged monitoring station communicates sensor data to a fixed or portable gateway, which can be hidden or placed out of reach.

Key features

• Fully submerged station with no cables for data retrieval, reducing theft, vandalism and tampering
• Integrates with multiparameter sondes (e.g. pH, temperature, turbidity, ammonia, dissolved oxygen, conductivity)
• Hands-free airbag retrieval: a remote command inflates an onboard airbag to raise the device without divers
• Topside unit can be placed up to 100 m from the river
• Through-ice operation (announced January 2026) for year-round monitoring under seasonal ice; the gateway uploads data to the cloud

Applications
