Abstract

A method of monitoring quality of extinguishing water in a sprinkler system by measuring electrical conductivity of the extinguishing water on at least one sprinkler head connected to an extinguishing water line. A quality and/or quality change of the extinguishing water is inferred from a measured conductivity value. A sprinkler head is disclosed that is suitable for carrying out the method. This sprinkler head has a connection fitting having a pipe section for connection to a free end of an extinguishing water pipe. A closure piece selectively closes the pipe section or free end of the extinguishing water pipe. A thermal trigger element holds the closure piece in a closed position in a normal state, and permits the closure piece to move into an open position at a trigger temperature. A conductivity sensor for measuring the electrical conductivity of the extinguishing water is provided on the sprinkler head.
