Smart Storm - Model USM -Water Quality Meter

FromSmart Storm Ltd.

SHARE

The USM water quality meter is a powerful and versatile meter that measures a wide range of environmental parameters. As standard, the USM will measure one of a number of ISE (Ion Selective Electrodes) plus an additional optional Modbus Electrode so the user can measure two parameters at the same time.
