DILUTION APPARATUS

摘要

PROBLEM TO BE SOLVED: To easily perform maintenance of respective flow rate sensors for a dilution liquid and chemicals and electric parts in an electric dilution apparatus. SOLUTION: The dilution apparatus is provided with a chemical flow rate sensor for detecting an amount of the chemical fed to a tank by a chemical feeding means; a water flow rate sensor for detecting an amount of dilution water fed to the tank by a dilution liquid feeding means; a dilution magnification setting button for setting a dilution magnification of the dilution chemical; and a control unit for controlling operation of at least any one of the chemical feeding means and the dilution liquid feeding means based on the predetermined value of the dilution magnification and the detected value of both the flow rate sensors. The dilution apparatus is provided with an operation displaying part capable of displaying any one of a control information and a maintenance information of the dilution apparatus; and a display switching means for switching a display mode of the operation displaying part from a usual mode for displaying the control information to a maintenance mode for displaying the maintenance information.
