I like a bit of simple home science. So, to help you out
@rayray119 I performed a small experiment using my Accu-Chek Aviva Nano glucose meter (specs are shown below) with a listed working range of 6°C to 44°C
Experiment
I have a thermometer in my refrigerator which shows 4°C, I took my meter out of my trouser pocket and put it into the fridge for 10 minutes. At the end of 10 minutes I took the cold meter out of the fridge and took a finger test. The test result matches my Libre.
Outcome
A good low temperature, compact meter.
