AcuRite Digital Wireless Fridge and Freezer Thermometer with Alarm, Max/Min Temperature for Home and Restaurants (00515M) 4.25" x 3.75"

I purchased this to monitor the temperatures in my Frigidaire refrigerator as I had an episode where items in the refrigerator (i.e. cans of water and a steak) were frozen and items in the freezer (i.e. fudge pops) were partially thawed and I was concerned my refrigerator was malfunctioning. The installation was straight forward with the unit coming to life immediately after installing the batteries in the 2 sensors and the base unit. Each sensor requires two AA batteries and the base unit unit requires three AA batteries. A total of 7 AA batteries are required. I installed Lithium batteries in the sensors as they have a broader operating temp range than alkaline batteries (i.e. good down to -63F). The base unit provides min and max temps in a 24 hour period which is quite informative. The base unit has magnets if you want to attach it to the exterior of the fridge or a pop up stand if you want to place it on top of your fridge, or it can be mounted on a wall. Very convenient. The only down side is that the suction cups for the sensors don't work. The suction cups popped off the wall of the refrigerator and freezer so I just have the sensors laying flat on the shelf. The unit is well worth the money I paid for it and I highly recommend it. In my case I set the temperature setting for the refrigerator to a higher setting and made sure the fr4eezer door was not left inadvertently open with temperatures confirmed by the Acu-Rite monitor as -1 F for the freezer and +37 F for the refrigerator. Perfect.

I can't attest to the specific accuracy, that it's within x degrees and so on, but what I can attest to is that it's very easy to read and it's more than accurate enough for my uses. I also love that it shows the high and low over the last 24 hours. The reason I got them is that my fridge one day lost it's temperature and some food spoiled but not enough to be obvious. We almost got sick but luckily caught it on time. As a result we bought this to monitor the temperature and it's been a great piece of mind to be able to just look at them at random times and know that the last 24 hours the fridge has always been within a certain acceptable range. They have been running on batteries for months and they are doing great. That being said I would recommend using two thermometers (why I bought this item because it comes with two) so that they can be located in different parts of the fridge. Not only does it give you more confidence that they are working and accurate at first, but later on you can locate them in different areas such as the door which has a tendency to have a lower temperature if it's been left open and so on.

good product, very happy with the purchase

... the frustration of a fridge/freezer in the garage stopping working and not noticing until a few days later, I know the pain involved in having to throw out perfectly good (and expensive) food. So, I resolved to stop it happening again and I purchased these. Reviews that are written after time and not when in the initial haze of consumer contentment always carry far more weight, in my opinion, and this is one such as I have had these since November 2022. I am writing this now because, thanks to these beauties, I managed to head off another fodder fiasco when a different fridge/freezer in the garage suddenly stopped: I fixed the problem before I had to throw anything away because I became aware of the issue in good time. At last - something I bought that actually SAVED me money !! These are fairly straightforward to set up (although to set the warning alarms takes a little effort) and I am pleased to report that the batteries (two AAs in each) I installed in both sensors over a year ago - ALWAYS use lithium ones if you want a better experience ! - are still functioning just fine (although I have changed the three AAs in the receiver unit on one occasion). I decided not to keep the alarms as I didn't want any potential beeping in the middle of the night, so I simply verify the temperatures every day. It's actually quite fun to think that you are checking on the temperature of an appliance outside of the house ! There is an easy-to-see record of the previous 24-hour's minimum and maximum temperatures at the bottom of the screen and one push of a button shows you all the lowest and highest temperatures from when you last reset the unit. All numbers are clear to read. I do think that this set is quite expensive, though (and it was £60 when I purchased it), but one's choices are somewhat limited and at least I can show that they do work, so I guess it equates to value for money - especially when one compares it with a cost of replacing the contents of a well-stocked fridge/freezer !! I have the receiver unit on the side of a fridge in the kitchen (decent magnets present) and the actual sensors are about 20 feet away in the garden behind a metal garage door; I have had no issue with signal strength. And that's about it. As is my wont, I shall update this review if anything ceases to function as it should. If there is something specific that you would like to know that I have missed out, please ask a question and I shall do my best to respond... FV

Las lecturas son confiables, los compré para tener más control de los alimentos que almacenamos en el refrigerador, apesar de que nuestro refrigerador tiene un display digital para ajustar la temperatura, no confiaba en la precisión y quise tener un segundo monitor con estos sensores y las lecturas son muy parecidas aproximadamente +-2 grados. La opción de sujeción no es muy buena ya que se caían constantemente, opte por simplemente dejarlo en la charola del refrigerador sin tenerlo colgado en algún lugar en específico. Muy recomendados
