Turbidity and temperature sensor for the deep ocean

ATUD-USB is an autonomously deployable data logger for long-term turbidity and temperature measurements in deep water. The temperature and turbidity sensors are highly stable, allowing for accurate data for long periods of time. Turbidity is detected through infrared backscattering and the sensor output has a good correlation with SS (Suspended Solid) over the range.

Parameter	Temperature	Turbidity
Range	-3 to 45 °C	0 to 1000 FTU (Formazin reference)
Accuracy	±0.02 °C (0 to 35 °C)	±0.3 FTU or ±2%
Resolution	0.001 °C	0.03 FTU

* The turbidity sensor is calibrated against formazin solution.
