Instrument Introduction
Built in 60 water quality indicator detection modes, capable of measuring water quality indicators such as COD, ammonia nitrogen, total phosphorus, total nitrogen, turbidity, chromaticity, suspended solids, etc.
Features
1) Android intelligent water quality detection system: smoother interactive experience, stable operation, and strong scalability;
2) 360 ° rotation color comparison: supports color comparison using a φ 16/25mm rotating tube, effectively reducing interference factors and increasing stability by 10 times;
3) Intelligent data sorting and analysis: The instrument supports data filtering and analysis, generating weekly/monthly data curve graphs;
4) Administrator permission settings: Built in administrator, allowing users to set their own permissions for easy management and ensuring data security;
5) Standard curve development and calibration: Custom calibration of support coefficient curves and sample curves to meet the application needs of regulatory agencies, research institutions, etc;
6) Intelligent IoT management: Data can be uploaded to Lianhua Cloud or connected to user databases;
7) On site photography: supports on-site photography and can be associated with detection data;
8) Exceeding limit warning prompt: supports setting indicator limit settings, and displays exceeding limits intuitively.
