Digital Sensor Method Multi-Parameter Water Quality Online Monitor
For River Industry Water
>>Overview
The AG9070 Multi-Parameter Water Quality Online Monitoring
Instrument is based on optical, electrochemical, and other
measurement principles. It can monitor multiple water quality
parameters, including temperature, pH, conductivity, turbidity, dissolved oxygen, COD,
ammonia nitrogen, nitrate nitrogen, chlorophyll, blue-green algae, and more.
Key Features
Display: 7-inch color touchscreen with a Chinese user interface for easy
operation.
Data Storage: Built-in storage, review, and export functions with customizable
storage intervals.
Signal Output:
a: 1× RS485 Modbus RTU standard protocol.
b: 2× programmable switch outputs (for controlling self-priming
pumps or automatic cleaning).
c: 5× programmable 4–20mA outputs (optional).
Password Protection: Secures calibration data to prevent unauthorized adjustments by
non-professionals.
>>Highlights
Modular Sensors: Digital smart sensors are plug-and-play, freely combinable, and
automatically recognized by the controller.
Flexible Installation: Choose between integrated or split-type configurations for
cost-effective deployment in diverse scenarios.
Auto-Calibration: Automatically reads sensor calibration history—no recalibration
needed when replacing sensors, saving time.
Robust Design: Advanced circuitry ensures ultra-low failure rates and strong
anti-interference capabilities.
Durability: IP65 protection rating for reliable indoor/outdoor performance
