Electronic Portable Scale

The image shows an Electronic Portable Scale, specifically the WH-A08 model, with a blue backlight function. 

Here's a breakdown of its features and uses:

Key Features:

Functionality: Primarily used for weighing items, it has a tare function to zero out the weight of containers. 

Display: It has a clear LCD screen with a blue backlight for easy reading in various lighting conditions. 

Weight Capacity: Typically has a capacity of 50 kg with an accuracy of 10 grams. 

Units: Supports multiple units, including kg, lb, oz, and jin. 

Power: Operates on 3V using two AAA batteries. 

Additional Features: Includes auto power off, data lock function, overload indication, and low battery indication. 

Portability: Designed to be lightweight and compact for easy carrying. 

How It Works:

The scale uses a high-precision strain gauge sensor system to measure weight.

When an item is hung on the hook, the sensor detects the deformation, which changes the resistance of the strain gauge. This change is then converted into an electrical signal and displayed as a weight reading. 

Common Uses:

Luggage: Ideal for weighing suitcases and bags to avoid extra baggage fees while traveling. 

Shopping: Useful for weighing groceries or other items while shopping. 

Home: Practical for various home uses, such as weighing packages or ingredients. 

Vendors: Can be used by vendors for weighing goods, although it is not recommended for commercial use. 

Additional Notes:

Some models may include a temperature measuring function. 

The scale is designed with a durable ABS shell and a stainless steel hook. 

This scale is a convenient tool for precise and portable weighing needs.
