Apera SX751 Handheld pH/ORP/DO/Conductivity/TDS/Salinity/Resistivity Multiparameter Meter Kit - AI469


AI469 SX751 Handheld pH/ORP/DO/Conductivity/TDS/Salinity/Resistivity Multiparameter Meter Kit by Apera

Apera SX751 is designed for lab-grade measurement of up to 8 water quality parameters in the field, including pH, ORP (redox), DO (dissolved oxygen), conductivity, TDS, salinity, and resistivity. It is suitable for general water solutions' applications such as water treatment, groundwater, surface water, hydroponics, environmental monitoring, aquaculture, aquarium, beverage making, etc.

Comes as a complete test kit in a rugged carrying case for convenient field test

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
