Portable condictivity meter CM 35
Ergonomic and robust instrument with IP67. Measures conductivity, salinity, total dissolved solids (TDS) and temperature. The range of cells covering a wide range of applications from clean water to viscous samples.
Simultaneous reading
It´s backlit LCD display allows simultaneous reading of the specific conductivity (salinity or TDS) to the selected reference temperature, the actual temperature of the sample and the duration of the measure.
Automatic change of scale
For reading with the highest resolution
