The DDB-11A portable conductivity meter is a 3 1/2 digit LCD digital display conductivity meter, which is suitable for measuring the conductivity of solutions in laboratories and production sites. Due to its small size and easy portability, it is particularly suitable for measuring the conductivity of solutions in places without AC power supply.
