Abstract
A fluid-ejection printhead die includes a fluid-ejection firing element and an electrochemical cell. The fluid-ejection firing element is to cause droplets of fluid to be ejected from the fluid-ejection printhead die. The electrochemical cell is to measure an electrical property of the fluid. The fluid-ejection firing element and the electrochemical cell are both part of the fluid-ejection printhead die.
