Conductivity (EC) Meter

B-771

Feature

Conductivity reading converted into Salt concentration and TDS. Autoranging & temperature

compensation feature allows accuracy on a measurements wide range.

Applications include

Fresh water testing (rain, rivers, lakes); aquaria; soil testing; salt water damage testing; surface

cleanliness testing and improved paint adhesion.
