WATER QUALITY MEASURING DEVICE
First Claim
1. A water quality measuring device comprising:
- a measurement cell configured to pool sample water;
a sample water supply unit configured to supply the measurement cell with sample water;
a reagent supply unit configured to supply the measurement cell with a reagnet to react with a water quality index substance;
an agitating unit provided at a bottom of the measurement cell;
a measuring unit configured to measure intensity of transmitted light of light having a required wavelength through sample water; and
a control unit configured to control operations of the sample water supply unit, the reagent supply unit, the agitating unit, and the measuring unit;
whereinthe sample water supply unit includes an inlet channel configured to supply the measurement cell with sample water and an outlet channel configured to discharge sample water from the measurement cell,the inlet channel is connected to a flow channel configured to supply sample water, and includes a filter and an electromagnetic valve, andthe control unit opens the electromagnetic valve for supplying sample water to allow sample water, from which foreign substances are removed by the filter, to flow into the measurement cell.

Abstract
A water quality measuring device comprises a measurement cell (10), a sample water supply unit (80), a reagent supply unit (30), an agitating unit (17), a measuring unit (20) and a control unit (90). The sample water supply unit (80) includes an inlet channel (12) configured to supply the measurement cell (10) with sample water and an outlet channel (13) configured to discharge sample water from the measurement cell (10). The inlet channel (12) is connected to a flow channel (2) configured to supply sample water, and includes a filter (13) and an electromagnetic valve (15). The control unit (90) opens the electromagnetic valve (15) for supplying sample water to allow sample water, from which foreign substances are removed by the filter (13), to flow into the measurement cell (10).
