Smart temperature monitoring for your fridge and freezer

The VLEJEARI 2 pack Refrigerator Thermometer with Extra Sensor helps you keep an eye on important temperatures in your kitchen. The main unit stays mounted outside the appliance while the flexible external sensor sits inside, connected by a 1.5 meter cable. With an indoor and outdoor alternating display and a clear high/low alert, you can quickly check temperatures at a glance and respond as needed.

Key capabilities you can rely on

Designed for precise monitoring across a wide range, this device covers -40 °C to +120 °C with a 0.1 °C precision. The high and low alarm settings can be tailored to your storage needs, and the alarm lasts for 60 seconds unless you press a key to silence it. When the temperature crosses your set thresholds, the LCD can flash to draw attention without being overwhelming.

• Dual sensing setup with an outer main unit and an inner sensor for accurate readings
• Large temperature span with fine 0.1 °C steps for careful monitoring
• Audible alarm that lasts 60 seconds and can be stopped by any key
• LCD indication and visual alerts if temperatures drift outside the set range

Set up and everyday use

Configuration is straightforward. The default high is 28 °C and the low is 18 °C. Long press the set button for 3 seconds to begin adjusting the values, use the up or down controls, and confirm with set. The system supports C to F conversion, so you can choose the unit you prefer. If the external sensor detects a temperature outside the desired range, the alarm will alert you promptly.

• Simple 3 second long press to enter settings
• Adjust high and low temperatures with up and down keys
• Display remains active even with the sensor mounted inside the fridge door

What you get and how to position it

Each pack includes two thermometers, one external sensor, a wall hook, a sensor hook, and a ready to use AAA battery that typically lasts over six months. The strong magnet lets you mount the main unit on the outside of the fridge for quick visibility, while the inside sensor is designed to be affixed in the fridge for direct readings. The device can also be used on a desk with the folding bracket or hung on a wall for flexible placement.
