This apparatus employs a state of the art wireless data acquisition system that collects and digitizes temperature, pressure, and air velocity data within inches of the sensors. This increases system flexibility while reducing system error, thermocouple material cost, and insulated envelope penetrations. These data are monitored by an automated computer control system that varies heater and fan output, calculates and records key variables, and determines the completion of experimental objectives. Using this system, it is possible to expedite the conduction of accurate thermal experiments with a minimum of human interaction.
