Pocket Balances
Pocket balances, also known as pocket scales or portable pocket-sized scales, are compact and lightweight weighing devices that can easily fit into a pocket. These scales are designed for quick and convenient weighing on the go. Here are some key features and considerations for pocket balances:
-
Compact and Portable: Pocket balances are designed to be small and lightweight, making them highly portable and easy to carry in a pocket, bag, or purse. This makes them convenient for various applications outside of traditional laboratory settings.
-
Weight Capacity: Pocket balances typically have lower weight capacities compared to larger scales. They are suitable for weighing small items and are commonly used for applications such as weighing jewelry, coins, medications, or small food items.
-
Battery Operation: Many pocket balances are powered by batteries, enhancing their portability. Some models may use standard batteries, while others use rechargeable batteries.
-
Units of Measurement: These scales usually support multiple units of measurement, such as grams, ounces, carats, and grains. The ability to switch between units allows users to weigh items in the desired measurement unit.
-
Tare Function: The tare function is useful for zeroing out the weight of containers or additional items, allowing users to measure only the net weight of the substance being weighed.
-
Display: Pocket balances typically have a digital display for easy reading of measurements. The display may vary in size and readability, so consider your preferences and needs.
-
Protective Cover: Many pocket balances come with a protective cover that not only shields the weighing surface during transportation but also serves as a tray for placing items to be weighed.
-
Auto-Off Function: To conserve battery life, some pocket balances are equipped with an auto-off function that turns off the scale after a period of inactivity.
-
Calibration: Some pocket balances may offer calibration features to ensure accuracy. Calibration weights or a known standard can be used to calibrate the scale periodically.
-
Accuracy and Precision: While pocket balances may not have the same level of precision as larger laboratory balances, they still offer sufficient accuracy for many everyday weighing needs.
These scales are commonly used by jewelers, hobbyists, outdoor enthusiasts, and individuals who need a portable and convenient way to measure small quantities. When selecting a pocket balance, consider the weight range you'll be working with, the required precision, and any specific features that may enhance your usability and convenience. Popular manufacturers include brands like AWS (American Weigh Scales), Tanita, and My Weigh.
