0.01 NTU Online Turbidity Sensor SUS316L Stainless Steel RS485 Modbus 0-4000 NTU Water Quality Monitor for Wastewater & Industry

Short Description:

The turbidity sensor is based on infrared scattering light technology. It receives scattered light in a 90° direction, and the intensity of the scattered light is proportional to the turbidity.

FAQ

Q: How accurate is the sensor for low-range turbidity?

A: It features an ultra-high resolution of 0.01 NTU. Utilizing 860nm infrared technology, it ensures stable and precise data even in the 0-10 NTU range, unaffected by ambient light or water color.

Q: Can it be used in seawater or corrosive environments?

A: Yes. Our standard housing is SUS316L stainless steel. We also offer a Titanium Alloy version specifically for seawater aquaculture and highly corrosive industrial liquids.

Q: Is the sensor waterproof for deep-water monitoring?

A: Absolutely. It is IP68 rated and designed for continuous underwater operation. The high-quality PUR cable ensures long-term durability for deep-water deployment.

Q: Is it compatible with my PLC or IoT system?

A: Yes. It supports the standard RS485 Modbus RTU protocol. With its slim 20mm diameter and G3/4 threads, it integrates easily into narrow pipes and various automation platforms.

Q: Does it require frequent cleaning or calibration?

A: All sensors are factory pre-calibrated. For wastewater or high-sediment applications, we recommend our self-cleaning version with an automatic brush to reduce manual maintenance.

Q: What's the lifetime of this Sensor?

A: Usually 1-2 years.

Q: May I know your warranty?
