EC-21 multi • EC-26 multi Portable Multi Meter

An elegant and ergonomic case, with a practical soft rubber and IP57 protection, contains the best of current technology. A large display (3-color backlit for EC-26multi) shows all information that you need.

All the functional parameters of connected electrode, during measurement or calibration, are constantly checked and inform the operator for easy trouble-shooting. The new DHS-technology allows the use of digital as well as analog electrodes.
Only 4 keys (6 for EC-26multi) allow the user to control all functions in an intuitive and easy way.
