A few practical questions.
Can I see live readings during transit?
U2 records for USB download after the journey. It does not transmit live cloud readings or location information. Compare V5B if you need connected temperature monitoring.
How does U2 compare with M1E?

Can the recording interval or start delay be changed?
The standard logging interval is 10 minutes and the standard start delay is 30 minutes. Other settings are available on request, so confirm requirements with RTDL before ordering.
Can U2 be reused?
The U2 model on this page is specified as single-use. Discuss available alternatives with RTDL if you need reusable monitoring.
Can I use U2 for an export protocol?
Check the required tolerances, placement and validation process before selecting a logger. The supplied specification lists ±0.5°C accuracy from −20°C to +40°C and ±1°C outside that range. RTDL can help review the requirements.
