AcuRite Matte White Digital Wireless Fridge and Freezer Thermometer for Home and Restaurants with Alarm and High/Low Temperature Records (00523M)

Something everyone should have. Accurate and excellent functions. It gives max/min temps daily. Should any problem occur with fan or compressors you might not know as shut down could occur at night. By morning after compressor cools it is working again. I should have had one years ago.

Nice product. Elegant style and works seamlessly. Having a serial number on it would make it professional and could be used for places need calibration and testing and tracing back the device, example usage is medication fridge for hospital and nursing homes. I wish the manufacturer would see this and include a serial number on it. Good product good price!!

I have boughten 2 off these digital wireless temperature monitors in the last 6 years. They have worked perfectly. They can be recalibrated too be used on two freezers. I can monitor the temperature on all the freezers and fridge in my kitchen.

Still really assessing!! I have only used one of the two units I purchased. I am using the Acurite as a secondary monitoring system as back up. I am monitoring critical medications at home in my freezer and fridge. I am using lithium batteries in the freezer thermometer and seems to be reasonably accurate most of the time. However, once or twice a day it will warm up significantly compared to my main monitoring system. I had to calibrate the fridge monitor a bit and seems to be ok. Quality and build seems to be nice and better than similar concept temperature monitors that are cheap and nasty. Interested to find out how long batteries will last, as I am hoping not to have to be buying batteries regularly.

I've had this in my garage freezer and house fridge for a couple weeks now, and they seem to be reasonably accurate, reading within a degree or two of my mechanical fridge/freezer thermometers. Keep in mind that these are measuring the air temperature, so the readings do fluctuate more than the food temperature. For example the food in my fridge is stable at 35*F, but the thermometer will show about a 10*F fluctuation as the fridge cycles on and off. You will need the lithium batteries for the freezer especially, otherwise you will get a constant low battery alert flashing on the screen since other battery chemistries can't handle the sub 32*F temps. Overall, these seem to be working just fine and I can see that my freezer in the garage is working properly which is my primary concern since I don't get into that freezer more than maybe once a week. The silicone loops make it easy to hang the sensors wherever you want without taking up storage space. I would buy this unit again. The price is reasonable, as is the accuracy for my needs. My only complaint is that it only shows a 24 hour history. It would be nice to have a longer term history, say 30 days or all time min/max, but thats a pretty minor gripe.
