Applications * Measurement of the cooling characteristics of a quenchant in the quench tank, in the following cases: - To check the cooling performance at various positions in the quench tank. - To check the effect of the flow rate on cooling performance. - To follow changes in the cooling performance of a quenchant - as a result, for example, of degradation or impurity - over a period of time. * Laboratory measurements. * Tests can be made with different quenchants e.g. oils, polymers, water and salts. * Incoming inspection of quenchants. Mode of Operation * A test probe containing a thermocouple is heated to the required temperature, normally 850°C and immersed in the quenchant. * The temperature change is recorded on computerized equipment and stored in memory. * After measurement, the temperature vs. time and cooling rate vs. temperature characteristics are plotted on a built-in printer. * The results may also be printed out in table form.
