What Is a Water Quality Transmitter

A water quality transmitter from Googolwater converts raw sensor signals into standardised digital or analogue outputs for display, logging, and remote monitoring. At Googolwater, our transmitters and data loggers work seamlessly with our full range of optical and electrode sensors. As a result, you get a complete end-to-end monitoring solution from a single supplier.

Our transmitters support RS485 Modbus RTU communication. Therefore, they connect directly to SCADA systems, PLCs, and cloud platforms. Furthermore, we offer both wired and wireless models to suit different installation environments — from indoor control rooms to remote outdoor monitoring stations.

Transmitters vs. Data Loggers

A transmitter is ideal when you need real-time data display at the measurement point. For instance, our Outdoor Water Quality Transmitter features a weatherproof enclosure and a built-in display for field operators. A multi-channel data logger, on the other hand, records and transmits data from multiple sensors simultaneously. For example, our On-site Multi-Channel Data Logger supports several sensor inputs and uploads readings to the cloud in real time. Meanwhile, it stores historical data locally for offline review. Together, these transmitter and data logger solutions cover every scenario — from simple single-point monitoring to complex multi-parameter network deployments.

Who Uses Our Water Quality Transmitters?

Environmental monitoring agencies, municipal water utilities, aquaculture farms, and industrial wastewater treatment plants use our water quality transmitters and data loggers. In addition, they deploy these devices in river and reservoir monitoring networks across more than 20 countries.

 All products carry CE and RoHS certifications. Our monitoring standards align with guidelines from the U.S. Environmental Protection Agency and the World Health Organization.
