Rules
Normal sudoku rules apply.
Along "slow" thermometers, values increase or stay the same starting from the bulb.
There are nine nullifier cells in the grid, one in every row, column and box. Each digit from 1-9 appears in a nullifier cell exactly once.
The value of every cell that orthogonally touches a nullifier cell is equal to 0. A nullifier cell's value is equal to its digit.
Solution code: Column 3

The minute I saw a 43-cell thermometer filling more than half of the grid, I knew I am in for a lot of fun. And it delivered. Thank you for setting and sharing this sudoku. "Nicolas Duhail" has become a synonym with "excellent puzzles".
