The size of the installation box is 500mm 400mm 173mm, and can monitor residual chlorine, temperature, pH value, conductivity and turbidity of water simultaneously. Compared with the existing similar products in the market, the method realizes the advantage of more monitoring parameters under the same volume. And wall-mounted installation can be realized, space is saved, and the wall-mounted installation is convenient for a user to use and install and is convenient for operation and maintenance.

The main control board is used as a control core, namely a main control unit, and is composed of a singlechip; and the man-machine interaction adopts a 5-inch touch screen to realize the control interaction, information output and data recording of the equipment.

When a certain measured parameter is higher than the upper limit threshold or lower than the lower limit threshold, the corresponding alarm output relay is attracted to generate an alarm signal, and a user can perform corresponding processing according to the signal. When the super-threshold alarm occurs, the red alarm on the right side of the equipment cabinet is started, and the buzzer is started, so that the audible and visual alarm is realized.
