iSPS-X Multi-Parameter Water Quality Measurement Instrument
The multi-parameter water quality meter is a measuring instrument that integrates pH/ORP, conductivity, salinity, dissolved oxygen (DO), turbidity, COD, TOC, ammonia nitrogen, nitrate nitrogen, and temperature into one instrument.
The instrument can be installed with up to four sensors to obtain water quality parameter data. Each sensor uses different electrochemical, optical, or physical detection means to measure the respective parameters. Users can read the measurement data through handheld instruments and the data acquisition instrument to transfer data to the data acquisition platform.
Parameter: pH, ORP, K+, EC, Salinity, TDS, NH3-N, NH4+, DO, Turbidity, TSS, COD, TOC, NO3-N, DOC, ChlorophyII-a, Blue-green algae, Temperature
- Quick measurement, shortest measurement cycle of 10 second
- No reagent consumption, environmentally friendly
- Long maintenance-free cycle, the sensor comes with a cleaning brush
- RS485 communication for fast connection to gauge heads
- IP68 protection for harsh environments
