CONDUCTIVITY METER CM35
Standards: EN-196-2
TWO INSTRUMENTS IN ONE
The conductivity cells normally used with the CM35 have an integrated temperature sensor. As a result, apart from measuring conductivity the instrument can be used as a thermometer up to 60 or 80 ºC epending on the cell used. By replacing the cell with an appropriate Pt 1000 probe the CM35 becomes a precision thermometer up to 600º C.
DOUBLE LCD DISPLAY
For simultaneous reading of the specific conductivity at the selected reference temperature, 20 or 25º C, and the real temperature of the sample.
A SMALL MOBILE LABORATORY
Optional carry case equipped with instruments, instruction manual, sensors, standard solutions 147, 1413 μS/cm and 12.88 mS/cm, protection to store the cell and small flasks for calibration.
