PWQ-2000 Tap Drinking Water Quality Monitoring System （Electrode Method）
Product Description
Quality is our culture, A professional water sensors manufacturer to make water analysis to be right for you!
The PROBEST PWQ-2000 Tap Drinking Water Quality Monitoring System is a professional-grade solution tailored for drinking water safety management. It integrates high-precision pipe network water quality monitoring sensors, an intelligent data processing unit, and an integrated internal water flow pipeline system—realizing 24/7 continuous monitoring of critical drinking water parameters. Core measurable indicators include temperature, pH (acidity-alkalinity), turbidity (water clarity), and disinfectant residuals (residual chlorine/chlorine dioxide), with optional expansion to conductivity (mineral content), ORP (oxidation-reduction potential), and other key water quality parameters. Designed to meet national drinking water standards, it provides reliable data support for water supply safety supervision, process optimization, and risk early warning.
Professional Disinfectant Monitoring: Adopts advanced constant voltage method for disinfectant detection, with optional dual indicators (residual chlorine / chlorine dioxide)—critical for ensuring drinking water microbial safety. The electrode features a simplified structure, easy cleaning and replacement, no need for diaphragm or reagent replacement, and ultra-low maintenance costs.
EPA-Certified Turbidity Detection: Utilizes EPA-standard 90° scattered light technology, equipped with a high-stability LED light source—offering low power consumption, long service life, and accurate measurement of turbidity (a key indicator of suspended particles in drinking water).
Integrated Space-Saving Design: Highly integrated internal wiring and waterway system, minimizing installation space. Users only need to connect power supply and inlet/outlet water pipes—achieving quick deployment and reducing on-site construction complexity.
Stable Water Flow & Accurate Data: Optimized internal waterway design ensures stable water flow during measurement, avoiding data fluctuations caused by flow instability, and guaranteeing high-precision monitoring results.
User-Friendly Intelligent Operation: Equipped with a 7-inch color LED touch screen, supporting operation even in direct sunlight. The interface is intuitive and easy to operate, with a reliable system structure and low maintenance requirements—suitable for on-site staff to use without professional training.
Comprehensive Data Management: Built-in data storage and real-time curve display functions, enabling users to grasp dynamic changes of water quality at a glance. Supports historical data download and trend analysis, facilitating traceability of water quality changes within a specific period.
Intelligent Fault & Alarm Management: Features automatic fault diagnosis, abnormal information recording, and remote uploading (e.g., component failure, parameter over-range, standard-exceeding alarms). Equipped with three-level management authority to ensure data security and operation standardization.
Flexible Connectivity Options: Optional wireless data transmission module (compatible with IoT platforms, 4G/5G/Wi-Fi) for remote monitoring and cloud data access—supporting smart water supply network management.
Waterworks & Water Supply Pipe Network Monitoring: Real-time monitoring of finished water quality in waterworks, as well as key nodes in urban water supply pipe networks (e.g., pipe network terminals, booster stations) to prevent secondary pollution.
Community Secondary Water Supply Detection: Compliance monitoring of water quality standards for secondary water supply (tanks, pipelines) in residential areas, ensuring the safety of tap water entering households.
Rural Tap Water Quality Supervision: Suitable for rural drinking water projects, monitoring water quality from wells, reservoirs, and other sources to meet rural drinking water safety standards.
Special Scene Drinking Water Monitoring: Real-time water quality monitoring for swimming pools, SPA centers, hotels, schools, and hospitals—ensuring the safety of daily water use in public places.
