Product Description

731 p2

SX731 7-in-1 Portable pH/ORP/Conductivity/TDS/Salinity/Resistivity Meter
SX731 is designed for lab-grade measurement of up to 7 water quality parameters in the field, including pH, ORP (redox),
conductivity, TDS, salinity, resistivity, and temperature. It is suitable for general water solutions’ applications such as water
treatment, groundwater, surface water, hydroponics, environmental monitoring, aquaculture, aquarium, beverage making, etc.


Basic Features
* Intelligent functions –– auto. calibration, auto. temperature compensation, self-diagnosis, data logging, auto. power off, and more.
* Digital filter technology –– enhance the meter’s response time and measurement accuracy
* Automatic electrode recognition –– the meter automatically switches to the right parameter mode according to the connected electrode
* Data logging –– 400 sets of data storage and recall
* Built tough –– IP57 water-resistant structure, ideal for use in harsh environment
