Product introduction of digital turbidity sensor

The digital turbidity sensor, designed in accordance with the ISO7027 standard method, is based on the principles of digital and intelligent sensor design, capable of automatically compensating for the effects of fluctuations in light source intensity and temperature changes on measurement values. It directly outputs standardized digital signals, enabling networking and system integration without the need for a controller. It is widely used in industries such as surface water and pollution sources.

Features of  turbidity meter

• The use of 875nm high-brightness LED as the light source eliminates the influence of sample color.
• Digital modulation coherent demodulation detection technology offers high precision, good stability, and strong anti-interference.
• Unique optical and electronic filtering technology is employed to eliminate the impact of ambient light on measurements.
• Built-in light source intensity reference detection is unaffected by light source attenuation.
• RS485 signal output enables integration and networking with other devices.
• Automatic cleaning with a cleaning brush significantly reduces maintenance workload.
• Easy to operate, supporting online software upgrades.
