A compact, easy-to use instrument which gives a quick and accurate detection of corrosive elements in cooling systems is now being marketed in this country by Car Plates, the sole United Kingdom distributors.
Called a Corometer. the device was developed and patented in the United States by HoyerStanyer Industries Inc., Kansas. It consists simply of a sensor, at one end of which is an indicator dial and a connector. A test of a cooling system occupies about 30sec.
The connector clip is attached to the radiator filler lip and the sensor inserted in the solution. The sensor is suspended in the solution ' at normal operating temperature: the needle-reading on the dial then indicates the corrosive quality of the solution. The instrument functions equally efficiently with anti-freeze, ordinary water or any mixture of water and engine coolants.
The dial is easy to read. A curved band is coloured green, yellow and red in equal segments. Each respective segment is marked with the words "good", "changeand "bad" The position of the needle when the instrument is being operated indicates the appropriate action to be taken with regard to the solution.
If the reading is -green", the coolant is satisfactory and no further action is needed. A "yellow" reading indicates that the radiator should be drained, flushed and refilled with fresh solution.
A -red" reading indicates that the cooling system is deteriorating rapidly and that the system should immediately be flushed out with cleaning compound and filled up with a solution containing active rust-inhibitors. This procedure may have to be repeated to bring th....1 Corometer reading to "good".
The Corometer requires no battery or other electrical connections. Its electronic components are sealed inside the thermal, shock-proof bodycasing which, like the sensor, is made of toughened nylon. Marketed by: Car Plates, Greasley Street, Bulwell, Nottingham. Price: £18.
