อุปกรณ์วัด Conductivity/TDS (Benchtop Meter for EC, TDS, NaCl, Temperature with USB output for PC connection

HI 2300-02 Benchtop Meter for EC, TDS, NaCl, Temperature with USB output for PC connection

HI 2300 performs measurements of conductivity  (EC), total dissolved solids (TDS),% of sodium chloride (NaCl) and temperature. The function of exchange-automatic scale for EC and TDS measurements set the measurement scale pi9 adjusted according to the measured sample.
All measurements are automatically compensated for temperature to 20 or 25  C.The value of the coefficient of automatic compensation  selectable. can also disable the temperature compensation and measure the value of cos  “conductivity  real”. The display on the large display of the indicator of stability , further guarantee of accuracy.
conductivity readings are obtained by applying the probe to 4 rings an alternating voltage that creates a variable voltage as a function of conductivity.
Functions GLP allow you to store and retrieve data about the status of the system.Thanks to GLP can call at any time last calibration data, together with the date and time. In this way is created a historian of instrumentation useful for the purposes of Traceability of the measurements performed.
With this tool is provided with a probe glass body to 4 rings made ​​of platinum and protective sheath of plastic material, suitable for applications in environments highly acidic or alkaline, and in extreme temperature conditions.
