Introducing KNF-400D: Next-Generation Drainage Water Quality Monitoring Equipment

As global environmental regulations tighten and the demand for sustainable urban infrastructure grows, accurate and reliable drainage water quality monitoring has become a top priority for municipalities, industrial facilities, and environmental agencies alike. KaiNaFu is proud to announce the KNF-400D Online Automatic Wastewater Monitoring System — a state-of-the-art monitoring equipment engineered specifically for drainage networks, sewer systems, and industrial discharge points.

System Overview

The KNF-400D is a comprehensive online water quality monitoring solution composed of three tightly integrated components: high-precision digital sensors, a low-power wireless acquisition terminal, and the proprietary Kenafu Cloud Platform. Designed with a modular architecture, the system allows users to configure and customize sensor arrays based on specific monitoring requirements — including pH, COD, ammonia nitrogen, turbidity, conductivity, dissolved oxygen, water temperature, water level, and oil-in-water detection.

Installation is remarkably simple. With no need for road excavation or complex civil works, a single KNF-400D unit can be deployed directly into existing manholes or drainage shafts within 15 minutes. This plug-and-play approach drastically reduces deployment costs and enables rapid large-scale rollout across urban drainage networks.

Key Features & Advantages

• Modular Sensor Array: Supports up to 8 water quality parameters simultaneously — pH (0–14), COD (0.5–500 mg/L), ammonia nitrogen (0–1000 mg/L), oil-in-water (0–100 ppm), turbidity (0–400 NTU), conductivity (0–100 ms/cm), liquid level/flow, and temperature.
• Low-Power Design: With per-sensor power consumption as low as 0.3W, the system can operate on a built-in 48,000 mAh lithium polymer battery for extended periods, enabling all-weather monitoring even in locations without grid power access.
• Automatic Cleaning Device (Optional): An integrated self-cleaning mechanism helps maintain sensor accuracy in harsh sewer environments, extending maintenance intervals to approximately 6 months.
• Multiple Data Transmission Modes: Supports RS485 (Modbus-RTU protocol), 4G wireless (GPRS), and NB-IoT, with configurable reporting intervals to meet diverse regulatory and operational requirements.
• Kenafu Cloud Platform: Real-time data collection, storage, and visualization powered by Cloud infrastructure. The platform supports PC web access, mobile apps (iOS/Android), WeChat binding, and automatic early-warning notifications. Data can be synchronized to LED displays and digital signage terminals.
• Zero Secondary Pollution: Reagent-free operation means no chemical waste, no consumables, and significantly lower total cost of ownership compared to traditional laboratory-based sampling methods.

Technical Specifications

Target Applications
