Simultaneous Monitoring of pH/DO/Turbidity/Conductivity/ORP/Temperature/Ammonia Nitrogen Boosts Efficiency by 300%
I. Industry Pain Point: The “Instrument Forest” Dilemma in Traditional Water Quality Monitoring
The field of multi-parameter water quality testing has long faced significant challenges:
- Proliferation of Equipment: Single parameter per device, requiring 7-8 instruments on-site
- Fragmented Data: Data isolated across instruments, time-consuming to integrate and analyze
- Cumbersome Calibration: Each device requires individual calibration, leading to high maintenance costs
- Delayed Response: At least 2 hours from sampling to complete report generation
Data from a 2024 Provincial Environmental Monitoring Center showed that in traditional methods, equipment preparation and data integration consumed 65% of total working hours, highlighting a severe efficiency bottleneck.
