Description
Overview
GAOTek Online Water Quality Sensor Test Meter offers a compelling solution for efficient and comprehensive water quality analysis. Boasting a competitive price point, this sensor meter amalgamates multiple crucial parameters – Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD), and Total Organic Carbon (TOC) – into a single, user-friendly system. The integration of ultraviolet (UV) technology enhances precision and sensitivity, enabling real-time monitoring of organic contaminants in diverse water sources. However, a more detailed evaluation of the sensor’s accuracy across varying water compositions, its long-term reliability, and compatibility with different industrial or environmental settings would provide a more nuanced assessment of its performance and value proposition.
Features
- Direct-immersion probe measurement without taking sampling and pretreatment
- No chemical reagents, no secondary pollution
- Short response time for continuous measurement
- Real-time sewage treatment organic load and water quality monitoring
- Continuous on-line monitoring of surface water, industrial effluent, and fishery wastewater
