Scope

Scope: This document specifies the structural composition, technical requirements, performance indicators, and detection methods of portable water quality rapid detectors. This document is applicable to the determination of chemical oxygen demand (COD), total phosphorus, ammonia nitrogen, and total nitrogen in surface water, groundwater, domestic wastewater, and industrial wastewater. This document is suitable for monitoring with high time-effectiveness requirements, large sample quantities, and samples that are not suitable for sending back to laboratories, such as environmental emergency monitoring, environmental supervision inspections, monitoring of river discharge outlets, environmental investigations, and environmental scientific research. Main technical content: 1. Scope 2. Normative reference documents 3. Terms and definitions 4. Structural composition of the instrument: Overall structure of the instrument, data acquisition module, data processing module, result display module, and auxiliary equipment 5. Technical requirements of the instrument: General requirements, operating conditions, safety requirements, and functional requirements 6. Performance indicators of the instrument 7. Detection items 8. Detection methods: General requirements, standard substance requirements, and instrument detection methods 9. Quality assurance
