Every high performance water sensors are available at treatment plants, but not at home where we actually get to drink the water. There are no other water sensors available for general consumers with high accuracy, rapid speed, low costs and easy-to-use features.

The brand, ‘WaTalk’ represents a series of IoT products that dramatically improve the quality management of tap water at home for general consumers.

The key competitive advantage of ‘WaTalk’ series is that the price is at least 10 times lower compared to our competitors, but without sacrificing accuracy.

The world’s best portable water sensor(by Hach Company) is for experts who monitor and manage the water quality of water supply and sewerage. This product is highly accurate(±0.02 NTU) but it costs 1,500 USD, not including the costs of consumables(vials) for each test.

The ‘WaTalk’ series have equally high accuracy(±0.02 NTU) but the cost is just 150 USD (15 USD for rental model). It is easy to use and understand the data with our mobile application. The small size allows users to carry it anywhere to secure their rights to drink only clean and safe water. 

CORE TECHNOLOGY 

• Core technology : multiple scattering. Signal amplification technology ensures low cost laser and image sensors while maintaining the same performance level as the conventional products 

• It is a low-level turbidity sensor that can check the quality of tap water, filtered water, purified water and/or bottled water by general consumers 

• The product’s LED lights provide water quality in three levels (good, normal, bad). The mobile app provides information that interprets accurate turbidity figures and data.  

• The turbidity in the pipeline and in home can be compared to predict the changes of infrastructure conditions for efficient water management system.

PATENTS

• Total 18 patents registered (4 US patents) 

• Total 65 patents applied (7 US patents) 

• Total 11 design patents applied

• Tumbler-type portable turbidimeter 
• High precision required for low concentration turbidity level (±0.01NTU) 
• Easy to check and manage data in mobile apps 
• Easy to use: automatic analysis with a single button
