The Mobile Data Collector comes in a small suitcase and can easily be sent all over the world together with the testing products and a manual for using the device, which will contribute to the geographic expansion of recruiting volunteers. It has a digital display and an interface for the computer. In addition the Ambient Condition Sensor RHT 100 is connected to the instrument, recording temperature and relative humidity for each measurement. The device can be programmed with the number of the volunteer. It can save over 3000 measuring values together with time, date, R.H. and temperature internally or on a chip card. The measurements can be executed by the volunteer him/herself several times a day over several days following a specially designed schedule at any place (e.g. at home, work, leisure etc.) as it is easy to use and carry around.
After the study is finished, the device is sent back to the laboratory. The values are read out with a simple software, which allows a database to be created which can be further processed by spreadsheet analysis e.g. in Excel®. The measuring values can also be sent from the volunteer to the laboratory during the study via the internet on a regular basis by just connecting the device to a computer using USB. The saved measuring data cannot be manipulated by either the volunteer or the laboratory.
At the moment, it can be delivered as a hydration measurement device. Other measurement parameters such as sebum or pigmentation/erythema measurement can be added to the system on request.
