Fine control handle / Faucet handle

We use running water when cooking, but it is rather hard to accurately control the required water amount every time, which is a waste of water and time. This fine control handle is designed specifically for this problem. Users can regulate the water yield by rotating the front end of the handle, respectively, 100ml, 500ml, and 1L. Users can rotate the front end of the handle to the required water yield, and water output will stop when it reaches the set amount.
