Conductivity meter for EC and TDS (amount of salts and dissolved solid materials)
With the conductivity meter PCE-CM 41 it is possible to measure conductivity value, the amount of all the solid material or dissolved salts (TDS - Total Dissolved Solids) and the temperature. The conductivity meter PCE-CM 41 is very easy to carry everywhere thanks to its small size. The water resistant enclosure protects properly the electronics (it also protects against dust). The measurement of EC and TDS conductivity has an automatic temperature compensation. The conductivity meter PCE-CM 41 has a wide field of application and can be used in the industry, fish farming, horticulture and others.
- Two measurement ranges for a high accuracy.
- Measures conductivity, TDS value and temperature (3 devices in one)
- TDS factor can be selected
- Auto shut-off: to protect battery life.
- Temperature in ºC of °F
- Water resistant (IP 67)
