AMIR Upgraded Refrigerator Thermometer, Wireless Indoor Outdoor Thermometer, Sensor Temperature Monitor with Audible Alarm Temperature Gauge for Freezer Kitchen Home (Battery not Included, Grey)

BOTTOM LINE: Affordable, simple way to monitor the temps in your refrigerator and/or freezers to insure that your food stays at the temps it should. Pop in batteries, set upper & lower limits and forget it. About as simple as it gets. Very happy. Well worth it for the peace of mind. 5 STARSTHOUGHTS: Having just filled our large chest freezer in the basement with a half Angus beef, I thought it might be a good idea to make sure things are staying at the proper frosty temps. Our freezer is decades old while it's always just chugged along without complaint, you just never know when it might give up the ghost. That'd be a helluva lot of perfectly good food (and money) gone to waste if it ever did. We don't go down there to pull food out or check on a daily basis so, after some internet researching, this inexpensive little remote thermometer seemed like a good way to keep tabs on things. As a bonus, this unit is set up for two individual sensors/monitored readings, so I placed the other sensor in the bottom drawer freezer in our fridge in the kitchen. Now they're both being closely monitored, so hopefully we'll never have any ugly surprises! Instruction booklet was helpful, but setting was an intuitive deal. Set upper & lower limits, decide whether you want an audible alarm for each sensor (about as loud as most cooking timer alarms) and place it where it's most convenient for you. (Receiver unit has a hole to allow for mounting on a nail or screw, a pop-out foot to allow you to set it upright on a counter or widow ledge, and 4 strong magnets so you can attach it to your stove or fridge. Main receiver unit takes 2 "AAA" batteries, remote sensors take 2 "AA" each. The manufacturer recommends using lithium batteries, for longer life. I'm not sure if regular batteries would last very long sitting in the single digit temps of the freezers, so I sprang for a set of Energizer Lithium batteries - just to be on the safe side.*** I also wanted to mention that when I got mine, I couldn't get a reading from Sensor #1. I tried different batteries and whatnot, but to no avail. I contacted the vendor (AMIR) and they quickly & politely responded with several suggestions, which I tried... but still no soap. I emailed them again and they offered me a complete refund and asked if I'd be willing to take a chance and re-order. I did, and within a couple of days the replacement arrived. When I put the batteries in, I quickly discovered that the fault with that first, original unit wasn't with the remote sensor but rather the main receiver/display monitor; the readout for sensor #1 was dead. Oddly, they said I didn't have to bother returning the defective original. So now I have a second one which only displays one reading, but rather than throw it away or let it sit in a drawer I simply used the fully functional replacement unit to monitor our freezer AND fridge upstairs, and now that original unit with only one working temp is dedicated to the big downstairs freezer. Now I can keep tabs on EVERYTHING being kept chilled or frozen. Win-Win! THAT is what I call outstanding customer service!

I use one in the refrigerator freezer and one in the big freezer because we arn't always in the big one and have lost a lot of frozen food out of a big one.

I have multiple freezers to store my meats and vegetables, and I recently purchased a new freezer and placed one of the sensors inside. It alerted me that the freezer had quit working. There was probably $809 worth of meat in that freezer. Since I had purchased this unit 2 years ago and never had a problem, so I never thought to keep checking the Temps. Thankfully I had the alarm set and it alerted me. It is a must have for anyone that has a freezer.

Here's the best review I can give at this time. Received unit and put fresh batteries first in base unit, then added batteries to each of the two sensors. All three sensors registered good temps within 10 seconds. I placed first sensor in deep freeze and second out in a unheated area. After stabilization, all 3 registered temps that were consistent with mechanical thermometers I already had in each location. I placed the main unit upstairs in living area, not far above the two remote sensors downstairs - separated by ~ 1" of floor material and R30 insulation, and the freezer sensor inside the freezer compartment. Both stayed connected to base unit. Contrary to an earlier review, all 3 sensor channels have independent and settable alarm settings. Base channel is intended as an indoor sensor, and the alarm settings are settable from -9C - 60C - if that doesn't cover most living areas, well you're hardier than me! The remote sensor channels are settable between -39C - 60C - totally suitable for most household deep freezers. Alarm limit setup is fairly straightforward - hold down the appropriate key 3 sec. for the channel intended, set the high limit, hit same key once, and set low limit, and hit same key once again. You can do this for each channel, including the internal/ base unit sensor - just stay within the limits stated. When the main display is on, the numbers displayed on the right may seem confusing, but they are simply the highest and lowest recent temps registered on that channel. Hit "Clear" once (Short - once), and they will reset and start registering recent temp changes again. WARNING: If you hold down the "Clear" key for 3 seconds, it resets everything and starts the process over - you may have to do that to reacquire sensors after replacing batteries, but will just cause you additional work otherwise! It would have been less confusing if there was a key to display "recent" vs "set alarm settings', but there's not. If you want to review your alarm settings, hold down the appropriate "Alarm Setting" button for 3 seconds. If the Hi limit setting is what you want for the hi limit, then hit same key again once (don't hold). If you wish to make a change, use +/- keys to adjust desired change, then hit same key again once. That will put you into the low alarm settings mode. Again, use +/_ keys to set to desired lo limit, or do nothing to keep current setting, then hit same key again and all settings you viewed are saved. NOTE: You have to set and/or view all alarm settings individually by sensor channel - all 3 are independent of each other! Actually, pretty straightforward and it works, and the instructions are accurate, albeit busy. But that's typical for any device that is performing multiple functions and few keys to program with. I found this one far more straightforward than so many other devices that require pressing multiple switches to perform necessary setup. As for alarm volume, you won't hear it unless you're nearby - that is why I placed base unit up in the living area. Yes, it would be nice if it were louder, but given the physical confines of the base unit, it is what it is. It was audible if I were nearby but it's not going to wake you up, or likely to be heard over loud ambient noise - but it is audible. This is a common complaint for most residential temp monitors on the market and I guess it is just a case of "when's the next best thing coming"! This one isn't any worse than others I've dealt with. Long term, not sure how battery life will be for the sensor inside the freezer compartment. Each remote has a battery condition reading so at least it can be monitored. I have 3 deep freezers at my place, each in remote locations, but 2 of them are visited frequently. I bought this one to monitor the one I don't visit that often but it holds a lot of valuable meat I would hate to spoil. The other two I have small lights plugged into the GFI outlets so I can do frequent visual checks on them - GFI's seem to be biggest culprits of things shutting down, especially if you experience periodic power outages. For the $$, this unit is working well for it's low cost.

For the price, this is quite amazing. The build is very solid, no flimsy plastic. The measured temperatures are accurate and sensitive. I was worried that I might have trouble with the sensors connecting to the display as my house is notorious for poor WIFI reception. But I have had zero issues with the two sensors in the basement connecting to the display on the main floor. I wish they made WIFI access points!

Works real well I use them in my kegerator and my spare fridge. My spare fridge doir sometimes does not close properly but this system lets me know when the temperature goes above a preset value.In my kegerator, I keep the temperature at 2⁰C but occasionally the temperature gets close to zero and I get a warning which is awesome.Works perfectly. No cons.

Très efficace, par contre un acheter il y a trois ans et un capteur ne fonctionnait plus , j’ai dû donc en commander un autre

Have one sender outside and one in the freezerManufacturer's seem to use sneaky cheaper ways of assessing fridge/freezertemperatures these days, especially 12v portables, so seeing what's actually going on might surprise you!Like the use of AA Batteries for longevityAmazon basics are pretty good.
