FAQ's of EXplore 171 Compact Turbidity Sensor:

Q: How is the EXplore 171 Compact Turbidity Sensor installed and operated?

A: The EXplore 171 is designed for easy, submersible installation in water bodies or treatment facilities. Simply mount the sensor at the monitoring location using its compact, durable body and connect the RS485 (Modbus RTU) interface to your control system. It automatically collects turbidity data with minimal intervention.

Q: What environments and applications are suitable for this sensor?

A: This turbidity sensor excels in a variety of settings, including drinking water plants, wastewater treatment facilities, industrial process monitoring, natural water bodies, and research projects. Its robust IP68 waterproofing and wide temperature tolerance let it perform reliably in challenging, humid, or even fully submerged situations.

Q: When should the sensor be maintained and does it require frequent service?

A: Thanks to its antifouling design and low-maintenance features, the EXplore 171 typically needs only infrequent cleaning and inspection, depending on water quality and environmental conditions. Routine checks ensure optimal accuracy and performance but are straightforward to execute.

Q: Where can this sensor be deployed and does cable length restrict installation?

A: The sensor is suitable for deployment both indoors and outdoors, wherever water turbidity requires monitoring. It comes with a standard 5-meter cable, but longer lengths can be requested for flexible installation in remote or deep locations.

Q: What is the measuring principle and why is it beneficial?

A: The sensor uses the nephelometric (90 scattering) principle, which accurately measures suspended particles in water by detecting light scattered at a right angle. This method ensures high sensitivity and precision, making it ideal for applications demanding strict water quality standards.

Q: How does the EXplore 171 benefit users in terms of data and integration?

A: It delivers real-time turbidity measurements with fast response, visible indicator LED, and robust RS485 Modbus digital interface for seamless integration into automated monitoring and control systems. This ensures timely detection of water quality changes and supports efficient system management.
