Freshliance 10packs USB Temperature Data Logger Recorder 129600 Points High Accuracy Cover 120days Single Trip Cold Chain Fresh Tag 1

Update: there is a 10 minute delay, and then these start to record. Also, if not in the temp range they will blink red every :30 instead of green. This could be better explained in the instructions. The delay info is written on the side so if you’re not careful it could be easily missed as it is obscured by the film bag that these arrive in. Otherwise they are simple to use.Held start button for 5 seconds as told, 3 green flashes, then yellow “delay” flash every 30 seconds for about 5 minutes, then single red flash every 30 indicating not recording.All 10 of these were the same, my experiment is compromised.

Unit turned on, but did not record data. Recording in progress light did not flash. No data in .pdf file that downloads. Very minimal documentation, no specifications, including how often readings are taken. No idea if it can be reset - no documentation. Returned.

It is a very useful and easy to use product. It helped me a lot regarding doing my work. I got a summary of the data logger recordings on the first page and all the data details on the next pages. It is quite easy to use. You just turn it on, and plug it in to get the data results.

Received quickly and work for their intended purpose.

Great product at a great price!
