Industrial plastic shell turbidity electrodeMainly used for turbidity testing in clean environments. Adopting the mature 90 ° scattered light principle from abroad, it supports submerged or pressurized installation and is suitable for water quality control in scenarios such as drinking water production, sewage treatment, and industrial water circulation.

Features:

1. Digital sensor, directly outputting Rs-485 digital signal

2. 90 ° angle scattered light principle, built-in temperature can automatically compensate

3. Fiber optic structure with strong resistance to external light interference

4. Infrared LED light source, with added filter design, resistant to light source interference, and good stability

5. Surface anti-corrosion and passivation treatment

6. Low power consumption of sensors and anti-interference design of internal circuits

Maintenance and precautions

1. Maintenance

It is recommended to clean the attachment of the sensor measurement probe every 30 days; Avoid using hard objects to scratch the light guide part of the measuring probe during cleaning; Please wipe with a soft damp cloth.

It is recommended to clean the outer surface of the sensor with water flow. If there are still debris residues, please wipe them with a damp soft cloth.

2. Precautions

Installation measurement: Avoid conducting installation measurement in areas with turbulent water flow to reduce the impact of water bubbles on the measurement. Keep the measuring probe 5cm away from the bottom.
