$10 — Aerostratospheric High-Altitude STEM Certificate

x2 Data Logger

Built for high-altitude science: a compact USB logger that rides through extreme temperature swings from the launch pad to near-space and back. Single-use. Plug into any computer for a PDF and CSV report — no software install. Records every 10 minutes without WiFi or any network connection, a true offline logger. Production is currently limited so some variations to design and branding are still probable. The Aerostratospheric X2 is a single-use USB temperature data logger built for high-altitude science. Balloon payloads leave a warm Illinois field, climb through a −50°C tropopause, and can see another swing on descent. X2 is made for that profile: a −30°C to 70°C sensor window, and a 14,400-point record you can dump to PDF/CSV the moment the payload is back on the benc Use it as a payload thermometer, a cooler/ground-truth check next to the launch stack, or a classroom instrument that shows students how fast temperature really changes with altitude or use it in fridge!
