HI98130 Pocket EC/TDS and pH Tester, High Range

This instrument is designed to obtain accurate measurements of pH, EC / TDS and temperature. It is no longer necessary to use 2 or 3 instruments for these measurements: in fact, this tester displays the pH or EC / TDS readings automatically compensated in temperature and the temperature value of the sample in degrees Celsius or Fahrenheit. To achieve more precise results in any particular application, the EC / TDS conversion factor and the temperature compensation coefficient ß can be set by the user.
