  • 7 inch color capacitive screen with high resolution (1024*600) and sensitivity, which can show more parameters, more intuitive, and simpler to read data.
  • Auto calibration, auto temperature compensation, data storage, USB data export, wireless printing, function setup, smart self-diagnosis and other intelligent functions.
  • Built-in memory can store 300 sets of test data which can be saved and transferred to USB flash drive and opened with Excel, very easy and convenient for edit.
  • DO mode has functions of ATC, auto salinity compensation and auto pressure compensation.
  • New structure polarographic DO electrode can measure temperature, salinity, and dissolved oxygen simultaneously, equipped with special DO electrode calibration sleeve, only need 3-5 min for polarization.
  • Combined diaphragm cap makes it extremely convenient to replace the sensitive membrane just by screwing the new cap to the electrode.
  • Auto recognition of 8 kinds of standard conductivity solutions and there are two series of standard solutions for option: USA series and China series.
  • Able to switch between conductivity, TDS, salinity, and resistivity. Multinomial calculation for TDS and salinity to ensure the conversion precision of the full scale.
  • IP54 dustproof and waterproof housing.
