KZTS-220 Self-Cleaning Turbidity Sensor
1. Core Advantages:
Digital signal sent out via RS485 directly.
Works well with MODBUS/RTU protocol.
Built-in cleaning brush keeps probe surface clean.
Reduces bubble attachment and cuts routine upkeep work.
Adopts 90° scattered light with internal fiber path.
Infrared LED and optical filter lower outside light disturbance.
316L stainless steel body with anti-corrosion treatment.
Runs steadily with low power consumption.
2. Maintenance Schedule
Auto cleaning function cuts manual work by nearly 80%.
Cleaning interval can be set from 1 to 24 hours on site.
Do two-point calibration every three to six months.
Calibration needed after probe cleaning or replacement.
Check optical window condition once every month.
Normal use allows 3 to 5 years service life for optical part.

4. How to Choose?
Pick KZSS-220 for activated sludge and high-solids sewage monitoring.
Pick KZTS-220 for drinking water, surface water and general water clarity testing.
5. Installation Best Practices:
Place the sensor at steady flow spots.
Keep away from dead water zone, bubble gathering and direct sunlight.
Can be installed by immersion, pipeline or wall bracket.
Link with transmitter, PLC and control cabinets for real-time view.
Use shielded wire for signal line and keep 12-24V power stable.

6. Maintenance Schedule
• Self-Cleaning: The built-in automatic cleaning system reduces manual cleaning by 80% – set the cleaning cycle (1-24 hours) via the control system.
• Calibration: Perform 2-point calibration (0 NTU & standard solution) every 3-6 months, or after probe cleaning/replacement.
• Probe Inspection: Monthly visual check for scratches, fouling, or damage to the optical window.
• Service Life: 3-5 years for the optical probe under normal operating conditions.
7. Industrial turbidity sensor Packing & Shipping:
All turbidity sensor models wrapped with waterproof film.
Add shockproof layer and strengthen outer package.
Load on standard non-fumigation pallet for safe delivery.

8. Common Troubleshooting
Recalibrate and clean window when reading is not accurate.
Check power and wiring if no signal comes out.
Adjust cleaning cycle once surface dirt builds up easily.
