It comes in a pack of two, each featuring a large, easy-to-read analog dial with clear blue and red indicators.

The thermometer is made of durable stainless steel, ensuring longevity and ease of cleaning. Additionally, it features a hook type panel design, allowing for flexible mounting options as it can be hung or placed in different positions within the appliance. While it excels in durability and ease of use, it lacks a digital display, which may be a drawback for those preferring more precise readings. Furthermore, it doesn't include an alarm feature to alert when the temperature deviates from the desired range, and there's no mention of water resistance, which could be a consideration for use in humid environments.

Despite these limitations, the PECULA Refrigerator Thermometer offers reliable performance and value, especially for those who prefer classic analog displays and straightforward functionality.

It also offers flexible placement options with magnetic backing, a stand, or a hook, so you can position it wherever it fits best.
