Its and integrated fridge/freezer, and the fridge already has this feature.. bizarre the freezer doesnt.. anyway... So, I needed a digital thermometer with an external probe (batteries dont work very well when frozen, so the electronics have to be on the outside). I read some good reviews of this item, and some bad reviews. The biggest themes were "its not accurate enough" and "I want the temperature inside my fridge, why do I have to use the OUT setting". I wasnt put off by the bad reviews for the following reasons : 1. My freezer should be at -20^C, and if it is at -5^C its warming up, and thats a problem. Even if the thermometer was out by 5^C, setting an alarm at -10^C would work.. as the temperature would be between -10^c and -5^c... both of which are a problem. I dont need a precise measure of the temperature, just a warning that it is climbing. 2. The thermometer is actually TWO thermometers... one is on the INSIDE of the unit, and one is OUTSIDE on the plug in probe. Most folk use these for measuring the temperature INside their house, and OUTside their house, hence the probe setting for the freezer is the OUT setting. Not too hard to comprehend. I ordered 9pm, and it arrived lunchtime the next day. Staggering, thanks desertcart! Its fairly self explanatory, pretty similar to most other battery powered gadgets.. OPen the battery door and remove the tab to activate. Plugged the probe in, there was only one place it would go on the bottom left side.. so cant really get that wrong. Ont he back is a button to flip between ^C/^F... pretty straight forward. The only bit I needed to refer to the "manual" for was setting the alarm. This could have been worded better, and a simple diagram would have helped. The basic idea is there are two modes... you're either setting a range for the alarm to trigger if it is within a range (for example, above 5^C, and below 10^C), or outside a range (for example below 5^C or above 10^C)... once that is clear, the poor description makes sense, and its pretty easy to set up. Mine was all up and running in under 10 minutes. Probably the best £12 of the year so far, as it is protecting £100's worth of food, and saving me the hassle of another defrost. The alarm is plenty loud enough too... I wouldn't hesitate to buy again, or recommend. Review: Good - Does the job ## Features - Easy to Read Fridge thermometer: more large digital display,more clear with the protector. Displays temperature in Celsius and Fahrenheit with high Accuracy (±1°C / ±2°F). - Double Alarm Function with LED Indicator: A. Hi/Low outdoor or freezer('OUT' reading is freezer temperature) alarm,you need to set the Hi/Lo temperature alarm; B. Frost point alarm. Two choices for you,more convenient. The Frost Point Alarm is a default setting of the temperature from -1℃～+4℃(+30.2℉～+39.2℉). - Flexible Installation: 2 different ways to install the fridge thermometer or indoor thermometer. Either use the stand to place it on the table-top,or mounts on the outside of your refrigerator with the magnet on the back. Cute design won't take more room of your refrigerator. - Simple to Operation: 4 buttons to complete the main functions of the digital fridge thermometer. IN/OUT Key: Inner and Outer(Fridge or outdoor) Temperature Conversion (Must insert sensor cable); MIN/MAX key: When it works, it will detect the max/min temperature automatically; AL key: set the alarm temperature range, open the alarm function; ADJ & ℃/℉ key: ADJ adjust the value under setted or change temperature unit between Celsius (℃) and Fahrenheit (℉). - Accurate Measuring: Thermometer Working Range: -10~50℃ (14~122°F); Sensor Cable Measurement Range: -50~70℃ (-58~158°F).

With the wide range of the temperature, it can also be use as a indoor/outdoor thermometer. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B072FJVSSL | | Age Range Description | Adult | | Age range (description) | Adult | | Best Sellers Rank | 21,966 in Home & Kitchen ( See Top 100 in Home & Kitchen ) 10 in Fridge Thermometers | | Brand | Gellvann | | Colour | Blue | | Country Of Origin | China | | Customer Reviews | 4.3 out of 5 stars 927 Reviews | | Display Type | Digital | | Immersion Depth | 7E+1 Centimetres | | Included Components | Battery, User Guide | | Included components | Battery, User Guide | | Indoor Outdoor Usage | Outdoor | | Item Length | 6 Centimetres | | Item Weight | 50 g | | Manufacturer | TopXun | | Manufacturer Part Number | 601 | | Model Name | Stander Gellman | | Number of Batteries | 1 LR44 batteries required.

Until now they have behaved perfectly, then yesterday the one monitoring the fridge started displaying -35 degrees which I knew was false as the fridge wasn't frozen up. Today the display disappeared altogether so I inserted a fresh battery, but that didn't help, the display remained blank. So I am ordering a new one. Overall I am happy with these units, as 3 years of constant use before failure doesn't seem too bad these days. Although it does lose one star because of this. ## Frequently Bought Together - Gellvann Digital Freezer/Fridge Thermometer with Magnet and Stander Digital Freezer Thermometer with LED Alarm Indicator Max/Min Memory Freezer Thermometer for Home Kitchen Restaurants Bars(Grey) - Fridge Thermometer Digital Refrigerator Thermometer, Suplong Digital Waterproof Fridge Freezer Thermometer With Easy to Read LCD Display (White-1) - Fridge Thermometer Refrigerator Thermometer,INRIGOROUS Pack of 2 LCD Digital Fridge Freezer Thermometer Monitor with Hanging Hook and Retractable Stand --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/204473978-digital-freezer-fridge-thermometer-with-magnet-and-stander-led-alarm](https://www.desertcart.co.za/products/204473978-digital-freezer-fridge-thermometer-with-magnet-and-stander-led-alarm) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-10-14*
