Total Suspended Solids / Turbidity Sensor with HydroMetrics IoT Telemetry

Get real-time, accurate, and reliable water quality monitoring with this low power use, optical TSS Sensor.

Designed for enhanced precision and durability, this optical four-beam self-compensating sensor virtually eliminates drift caused by contamination or electronic aging — ensuring long-term stability and performance.

Why this TSS Sensor?

1. Unmatched Accuracy – Delivers repeatable, high-precision readings via 4-beams for effective monitoring.
2. Easy to Use & Install – Simple 2-point calibration via USB and a simple interface.
3. Reliable Remote Monitoring – Compatible with 4-20mA, Modbus RS485, and SDI-12 connections.
4. Versatile Applications – Ideal for stormwater monitoring, flocculant dosing, and wastewater management.
5. Extended Range – Measures 0 - 2.5g/L (contact us for other levels).
6. Low Power: designed for remote installations with only a small PV panel / battery required.

Pair with our HydroMetrics SDI-12 Telemetry for seamless data collection. Band 28 IoT coverage is required — contact us to check availability in your area if you are outside Australia or New Zealand.
