sx713 portable conductivity/ tds/sal./res.meter
    the most cost effective portable conductivity meter, measurement of conductivity, tds, salinity and resistivity of water solutions, suited for industrial and mining factories, water treatment engineering and environmental protection field, especially suited in field and on-site.

● built-in microprocessor chips, intelligent functions such as automatic calibration, automatic temperature compensation, data storage, function set-up, automatic power-off and low voltage display.
● automatic identification of 8 conductivity standard calibration solutions, two options of standard calibration solutions: europe and america series and china series.
● adopt advanced conductivity measurement technology, use conductivity electrode of constant k=1, only need one point calibration and meet the measurement precision requirement of 0.5μs/cm ~ 200 ms/cm.
● ability to switch among conductivity, tds, salinity and resistivity. multinomial calculation for tds and salinity to ensure the conversion precision of the full scale.
● conductivity measurement mode has the function of non-linear temperature compensation for high purity water.
● plastic conductivity electrode with automatic temperature compensation, fast response and accurate result.
● meter meets ip57 rating, equipped with calibration solution and portable case.
