Реферат: A method and apparatus are disclosed for externally and noninvasively determining the temperatures of chemical reactions inside a plurality of separate closed vessels that are made of materials that substantially transparent to microwave radiation but that are poor conductors of heat. The method comprises exposing a plurality of substantially microwave-transparent of vessels containing chemical reagents therein to microwave radiation, concurrently measuring the temperature of the reagents inside a first vessel using a first temperature sensor inside the first vessel and while measuring the temperature of the exterior of the first vessel using a second temperature sensor positioned externally to the first vessel, and immediately thereafter successively measuring the temperature of the exterior of the remainder of the vessels using the second sensor.
