Smart Q secondary sensor range

Rather than simply measuring surface temperature, this sensor measures the energy transfer from or to an object in Watts per square meter.

When the sensor is placed against a flat surface, the differences in the rate of temperature changes between the two sides of the sensor are used to determine the flow of heat. Objects warmer than their environment show a positive heat flow, whereas those cooler show a negative value.

Applications:
Physics:
Investigating insulation properties
Newton's Law of cooling
Heatflow to cold objects
Heatflow from hot objects
Biology:
Heat loss from the body e.g. through clothes; from different parts of the body etc.
General:
Heat flow or loss in buildings e.g. through single and double-glazed windows; from different materials used for glazing; different areas of a door; different building materials.
