Dual beam 90° 140° Digital RS485 Turbidity and TSS Sensor
>>Technical Parameter
The AG-302 digital turbidity sensor, designed based on the ISO7027 standard method and adopting a digital, intelligent sensor concept, automatically compensates for the impact of light source intensity fluctuations, temperature changes, and other factors on measurement values. It directly outputs standardized digital signals, enabling networking and system integration without the need for a controller. Widely used in industries such as surface water monitoring and pollution source detection.
>>Feature
● Utilizing a high-brightness 875nm LED as the light source, eliminating the influence of sample color.
● Dual-beam (90°+140°) design for wide dynamic range measurement.
● Digital modulation coherent demodulation detection technology, ensuring high precision, excellent stability, and strong anti-interference capability.
● Advanced optical and electronic filtering technology to eliminate the impact of ambient light on measurements.
● Built-in light source intensity reference detection, unaffected by LED degradation.
● RS485 signal output, enabling seamless integration and networking with other devices.
● Automatic cleaning brush, significantly reducing maintenance workload.
