Abstract: A temperature measurement device is provided for monitoring the temperature of a temperature-sensitive product, e.g., a blood product. The temperature measurement device may include multiple different types of temperature sensors, e.g., at least two of the following types of temperature sensors: (a) a product-interfacing temperature sensor in thermal contact with the product, (b) an on-chip temperature sensor of a microprocessor or microcontroller, and/or (c) an ambient temperature sensor configured to measure an ambient temperature external to the product.
