Compact City-Water Analyzer

MWB4-70

This analyzer is for continuous monitoring water quality
(Maximum seven parameters) at faucet feed line or water
receiving tank of a building.
In addition to the three items of turbidity, color, and
residual chlorine, which are specified by law to be
inspected daily, this analyzer can optionally conduct
measurements of the electric conductivity, pH, water
temperature, and water pressure.
The compact B4-size allows the MWB4-70 to be
installed in narrow spaces. The MWB4-70 also delivers
high reliability, durability, and excellent maintainability.

signals, “Caution” and “Warning”, thereby enabling users
to identify the severity of the problem.
