A measurement device for determining heating parameters of an oven may generally include a support plate and at least one sensor cup coupled to the support plate. The sensor cup may define a liquid well for receiving a volume of liquid and may include a bottom wall defining a floor of the liquid well. In addition, the measurement device may include a temperature sensor positioned adjacent to the floor of the liquid well such that the temperature sensor is configured to be in fluid contact with at least a portion of the volume of the liquid received within the liquid well. The temperature sensor may be configured to monitor a temperature of the liquid as the liquid is heated and evaporates from the sensor cup.
