Abstract
Non-boil boiling point indicator includes a probe housing having inner and outer chambers and a heater located within the inner chamber at a free end of the probe housing. The probe housing has a free end provided with non-restrictive apertures. Similar non-restrictive apertures are located between the inner and outer chambers and from the outer chamber to an outer environment surrounding the probe housing. The temperature of the test fluid is monitored by a temperature monitoring device. As the test fluid is rapidly heated, its temperature quickly rises then flattens out before boiling point. This change is used to extrapolate to the boiling point. Localized steam or vapor bubbles are created next to the heater, which causes the test fluid above the heater to be propelled upwards and overflow through the unrestricted apertures at the top of the inner chamber into the outer chamber.
