Abstract
A testing device () for testing the level of a selected chemical in central heating system water in a central heating system circuit comprises: a sample chamber () for holding a sample of central heating system water to be tested, the sample chamber () being connectable () to the central heating system circuit to allow fluid to pass between the central heating system circuit and the sample chamber (); means () for controlling filling of the sample chamber () with central heating system water from the central heating system circuit, and emptying of the sample chamber (); at least one valve () for isolating the sample of central heating system water from the heating circuit during testing; and optical testing apparatus including a light source () and a detector (), for measuring an optical property of the sample of central heating system water isolated within the sample chamber () and thereby making a determination as to whether or not the level of the selected chemical in the water is greater than a predetermined threshold level.
