Abstract

Apparatus for testing scale deposited from a flowing liquid e.g. water comprises at least one plate (20) and preferably a stack of plates (20) formed on one or both surfaces with a spiral (or other form) groove (17). The liquid flows into the top plate (20) of the stack from the periphery (26) to the centre (18), down to the next plate (20) where it flows from the centre (18) to the periphery (16), down to the next plate (20) and so on. When the test has finished the stack of plates (20) can be dismantled very readily and the deposited scale tested e.g. by chemical analysis or X-ray or electron radiation techniques. The plates (20) can be cleaned very easily for a further test and the apparatus is very compact so that it can be used readily for testing on site (in the field). <IMAGE>
