  • Warranty
  • 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.



    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

    pH Features

    • Built with lithium glass membrane and fiber ceramic junction, the 201T-S pH/temp. electrode provides the foundation for quick response and accurate pH readings.
    • 1 to 3 points of quick auto. calibration, recognizing up to 13 kinds of pH buffers.
    • The self-diagnosis function helps you understand common problems and how to fix them.
    • With the 8-pin to BNC converter (sold separately), a variety of LabSen pH electrodes can be connected to meet the testing needs of specialized applications.


    Conductivity Features

    • Built with Apera’s proprietary platinum black, the 2301T-S conductivity/temp. electrode ensures high accuracy (±1% F.S) in a wide-range (0 to 200,000 µS/cm)
    • Simple 1-point automatic calibration, recognizing up to 8 kinds of conductivity standards
    • Easy switch to TDS, salinity, and resistivity
    • 0 to 50˚C Automatic temperature compensation
    • Non-linear temperature compensation will be triggered if the sample’s conductivity is <10µS/cm, significantly increasing the reading accuracy for pure water.


    DO Features

    • Equipped with Apera's DO500 polarographic DO electrode, featuring quick response and integrated temperature and salinity sensors.
    • Replaceable DO membrane cap (3 replacement membrane caps and an inner solution refill are included in the kit).
    • Regular electrode polarization only takes 5 minutes. Measurement reaches 90% response within 30 seconds. 
    • Automatic compensation for temperature and salinity; manual compensation for barometric pressure


    ORP Features

    • Equipped with 301Pt-S Platinum ORP electrode featured with stable potential and fast response
    • No need for ORP calibration
    • The platinum sensor is easy to clean and maintain


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