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

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.

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!!

Really like being able to put sensors in my fridge/freezer and seeing the results on the exterior. My refrigerator has a textured surface so the exterior display has a tendency to slip. I place a small magnet below, which prevents that. Temperature accuracy seems inline with my TempPro thermometer. The sensors can either be hung from a wired shelf or using the included suction cups. I ordered the white model, but I wish I would have ordered the silver version for my black refrigerator. I do like it and would recommend it for anyone wanting to monitor temps.

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 two of these for a few years now (originally got one for the kitchen fridge, then bought a second unit for the deep freezer.) The pluses and the minuses are below. First, the minuses: The first thing is that this is supposed to be able to stick to your fridge magnetically. But, they cheaped out on the magnets. The magnets in the back are NOT strong enough to hold this device onto the fridge. The motion of the door makes it fall off, and when not falling off, it is gradually sliding down. We added some heavy-duty magnets between it and the fridge to keep it on there. The second thing to know is that the freezer sensor on the first one I bought went bad, after less than 2 years of use. You can't buy replacement sensors, so I ended up buying a whole new unit. I hope that this is a fluke, and the current units last longer. I will update. The pluses: I have a temperamental refrigerator. It came with the house and it still runs so I would rather use it than replace it. But it's very responsive to changes in barometric pressure. Sudden cloudy or rainy days? The refrigerator temps drop and things freeze. An engineer friend explained it to me once but I don't really understand it, I just live with it. I like having the temperature display on the front of the fridge so that if there's a problem, I can see it right away. I also like that this device has a safety alarm if temps get too low or high. The device works for that. The batteries need replacement every 6 months or so.
