Multi-parameter Water Quality Analyzer GWQ-MP200
Empowering Modern Agriculture & Fertigation

From source water to root zone — real-time monitoring of pH, EC, dissolved oxygen, residual chlorine, COD for higher yield & quality
📍 Project Location: Smart Agriculture Industrial Park / Highland Vegetable Base
🌾 Application Scenarios: Greenhouse soilless cultivation, fertigation integrated irrigation, seedling water quality control
📅 Implementation: 2024 – present  |  Equipment: GAIMC GWQ-MP200 Multi-parameter Water Quality Analyzer (1-6 channels, supports pH/EC/DO/Residual Chlorine/Turbidity etc.)
🌾 Water Quality Challenges in Agriculture & GWQ-MP200 Solution
In modern facility agriculture, irrigation water quality directly affects root vitality, fertilizer efficiency, and soil-borne disease risks. Traditional single-parameter testing is inefficient and lacks real-time insight, making it difficult to precisely control nutrient solution EC/pH fluctuations, leading to reduced yields or physiological disorders. The GWQ-MP200 Multi-parameter Water Quality Analyzer features a real-time operating system (RTOS) and can simultaneously connect digital sensors for pH, conductivity (EC/TDS), dissolved oxygen, residual chlorine, turbidity, COD, and more. It enables 24/7 continuous online monitoring of irrigation water, return solution, and source water. With RS485 and 4-20mA outputs, it seamlessly integrates with fertigation controllers, making every irrigation data-driven.

📈 Proven Results: 12% Yield Increase, 15% Water Savings
In a large-scale greenhouse tomato cultivation area, the GWQ-MP200 continuously monitors pH and EC in the main irrigation line and return tank, automatically adjusting the fertigation machine. After 6 months of operation, nutrient solution pH remained stable between 5.8-6.2, EC fluctuation reduced by 64%, tomato blossom-end rot incidence dropped by 42%, total yield increased by 12%, and water/fertilizer efficiency improved significantly. Meanwhile, residual chlorine monitoring ensured effective biofilm control in end pipelines, reducing emitter clogging by 35%.
