What is a data logging USB?
A data logger is a tool used to record a variety of parameters, which can include, temperature, humidity, dew point, current, voltage, and carbon monoxide. The logger is used in the field to record data, then brought back to a computer to collect/graph what was collected. These data loggers are ideal for applications such as: calibration labs, environmental chambers, pharmaceutical plants, and storage warehouses.

In HVAC systems, there are many different parameters that are commonly measured for system performance or building comfort. Some of the most commonly measured HVAC system parameters are temperature, air velocity, humidity and static pressure. Of those parameters, static pressure is extremely important in terms of system performance. Static pressure indicates how hard the HVAC system has to work to move air through the building or how much resistance to flow exists. The higher the static pressure, the harder the system has to work to move air through the building. 
Radon is a naturally occurring radioactive gas that comes from the decay of Uranium. It is often found in the rock and soil upon which many residential and commercial buildings are built.
