NS-ZS602 Digital Turbidity Sensor

Product Introduction
The NS-ZS602 Digital Turbidity Sensor is a submersible water quality sensor designed for continuous turbidity monitoring in industrial and environmental applications. It uses infrared optical technology to measure light absorption and scattering caused by suspended particles in water, providing reliable turbidity readings over a wide measurement range.
Equipped with RS485 digital communication and 4–20mA analog output, the NS-ZS602 can be integrated into online water quality monitoring systems, PLCs, and industrial control equipment. Its automatic wiper cleaning function, five-point calibration, and IP68-rated housing make it suitable for long-term monitoring in demanding environments.

Performance Features
• Infrared optical measurement: Uses a stable, near-monochromatic infrared light source to reduce interference from water color and ambient visible light.
• Optical compensation: Built-in light intensity compensation improves measurement accuracy and stability.
• Dual signal output: Provides 4–20mA analog output and RS485 digital communication.
• Automatic wiper cleaning: Adjustable cleaning intervals from 1 to 30,000 minutes help reduce maintenance requirements.
• Advanced optical detection: High-transmittance quartz glass lenses support stable infrared light transmission and reception.
• Strong anti-interference capability: Designed to reduce the effects of ambient light on measurement.
• Wide measurement range: Standard range of 0–4000 NTU, with customized ranges available.
• Stable performance: Designed to provide good repeatability and measurement stability, independent of sample flow rate and pressure within the specified operating conditions.
• Flexible configuration: RS485 communication supports sensor address, baud rate, online calibration, range, output range, and compensation settings.
• Five-point calibration: Supports multi-point correction for measurement adjustment.
• Watchdog function: Helps prevent system freezing during operation.
• Durable construction: 304 stainless steel and ABS housing, with IP68 protection.
• Long-term data protection: Power-loss data protection exceeds 10 years.

Working Principle
The NS-ZS602 measures turbidity using the infrared light scattering and attenuation principle. Its infrared emitter sends light through the water sample. Suspended particles and colloidal substances absorb, reflect, and scatter the light as it travels through the water.
A detector receives the optical signal at a specific angle. The sensor's internal processing unit analyzes the received light intensity using a dedicated algorithm to calculate the turbidity value.
The near-monochromatic infrared light source reduces interference from water color and ambient visible light. Built-in optical compensation further helps improve measurement stability. The automatic wiper periodically cleans the optical surface to reduce contamination and maintain reliable readings.
