Description

The Datalogger STRATO4 was developed by the engineers at Stratoflights specifically for recording measurement data from stratospheric flights and records data up to an altitude of 50,000 metres. With the Datalogger STRATO4, the secret of the altitude reached can now finally be revealed. In addition to the altitude and GPS position and thus the speed, the STRATO4 records further measurement data such as humidity, indoor and outdoor temperature, UV and infrared radiation, air pressure and much more on a microSD card every 2 seconds. After the flight, the data can be easily analysed on the PC with the Datalogger Evaluation tool. The tool creates numerous graphics with just a few clicks and, as a special highlight, the flight route can be displayed as a 3D curve in Google Earth. Via a serial interface, the data logger offers the possibility to read out the data for own extensions. The enclosed sensors can be attached outside the probe via a 30 cm long cable, so that the data logger is safely protected inside against the extreme influences of the stratosphere. Its lightweight and space-saving design makes it ideal not only for reaching maximum flight altitudes with the weather balloon, but also for launching a real research flight into the stratosphere thanks to the extensive data collection. Operation is very simple, all values are shown on a large colour display and no programming knowledge is required. Thus, the Datalogger STRATO4 belongs on board every stratospheric flight.
