A colleague bought a 5-pack of them and scattered them around her labs. You
and put them into your lab(s) at various places. When you need the
unattended for many, many months. It has a much larger memory than the
a bit more expensive than the Lascar one. I actually leave it shoved in a
next to our Ti:Saph. I usually check it a few times a year.
recommend one of the Lascar 5-packs. If you only want/need a single logger
time due to its larger memory, at very short intervals. I leave mine set to
record temperature and humidity every half-hour. Some versions of the MSR
status lines on your equipment if you want to monitor something else. Again
