WHAT is R.O.C. and WHY IS IT THE BEST WAY TO DETECT AN OVER-HEAT CONDITION BEFORE A PROBLEM GETS SERIOUS?
RATE OF CHANGE (R.O.C.) is the use of a rapidly changing temperatures (usually 3°C per minute) to trigger an alarm. One can readily see the advantage to using ROC because it can trigger an alarm well before a product damaging condition occurs. Anywhere from minus 40°C on up. The parameters of ROC can be defined in an instrument (see Instruments) or in the computer software.
