I really wanted a model that would guard both my freezer AND refridgerator (this does one OR the other by default), but couldn't find one. However, by taking out the internal (room) sensor (it's extremely small but easily found inside), and soldering it to a lead, Maybe the manufacturer could make a similar modification to a future version. With this simple modification I finally I got what I wanted: a thermometer that shows the temperature of both compartments AND warns if the freezer temperature rises too high. (I know I voided the warranty but hey, this isn't rocket science). Since this is battery operated it will warn even if the mains fail. Also, the color matched the front plastics of my refridgerator, so when I fitted it in there it looked like it had always been there. The warning ...

The warning sound is exactly right, not too loud and not too quiet.

CDN Audio Visual Refrigerator Freezer Alarm Thermometer Temperature Good Within Limits
This item is a decent buy, but has its flaws. The wire which must pass through the door gasket can allow air to infiltrate and allows for a bit of melting, frost and ice to occur on your freezer. I own four of these and the two being used on older models with older (and stiffer gaskets) have this problem. They did not have the problems before the wire was there. You will need to devise a better way to seal around this. I have not attacked this problem yet but I am resisting changing the door gaskets and will try to apply some sort of sealer or caulk to the wire. Another way to avoid this problem would be to use the thermometer intermittently instead of constantly although this might only serve to defeat you purpose. Also the alarm is not loud, so I would not count on hearing it. ... This item is a decent buy, but has its flaws.

This item would also be good to monitor unheated spaces without requiring you to open a door to get a temperature reading inside of the space.

Fridge saver
Twice already this little alarm has saved my fridge!! The doors on my double door fridge need to be pushed shut unlike my old one that would just close by itself and seal. Since I am not in the habit of 'pushing' the door shut I often neglect to do it. With the door open a tad the light stays on and warms up very quickly which over time leads to major ice build up in the bottom freezer, etc. So I love the thermometer/alarm even though it is lightweight and made in China.Twice already this little alarm has saved my fridge!!

CDN TA-20 Freezer/Refrigerator Monitor
CDN TA-20 wired Refrigerator Alarm is a good alternative to wireless monitors but has 2 minor issues both involving the temperature sensor. First, the wire is too short (..less than 3 feet long) limiting where you can place the main unit. Secondly, most applications require the wire to pass between the gasket and the frame compromising the air-tight seal you want. The wire needs to be longer and you need to be creative in running the wire. In my case, I was not using my ice maker so I ran the wire through the water port and out the back of the freezer. The refrigerator is another challenge. Alarm is loud enough to be heard from 2 rooms away. Unit seems to be pretty accurate. All & all, a must have for all refrigerator and freezers. Hope this helps.

Useful for Medical Couriers
In my job as a medical courier, I pick up medical specimens that are temperature critical. Some must be frozen (think dry ice), refrigerated (50-60°F), others kept at ambient temperatures (60-80°). These thermometers can be used for either freezer or refrigerator temperatures using the attached remote sensor, plus the ambient temperature outside the coolers. It has an alarm that you can set when the temperature exceeds the preset limits. Runs on 1 AAA battery (included) for a long time. My first one has lasted 2 years on same battery.In my job as a medical courier, I pick up medical specimens that are temperature critical.
