Description

Floating Water Quality Measuring Device The present invention relates to a floating water quality measuring device. To measure water quality parameters such as dissolved oxygen, pH, and ORP (oxidation reduction potential) using electronic sensors in oceans, rivers, streams, tanks of large-scale water treatment facilities, and small tanks of water model simulators, sensors must be installed at a specific height. These measurement sensors are equipped with semiconductor components to convert signals internally and cables to transmit the measurements. In water quality measurement environments, fluctuations in water levels can cause the semiconductor components and cables to become submerged, leading to short circuits or damage. Consequently, expensive waterproofing is required for these sensors, which can increase the cost of water quality measurement. In addition, depending on the water quality measurement environment, bubbles, foreign substances, etc. may enter or adhere near the sensor tip of the water quality measurement sensor, resulting in inaccurate measurement results or requiring repeated cleaning.
