A jewelry balance is a device designed to accurately weigh diamonds, gemstones, gold, silver, and other precious metals. Our jewelry scales and balances are made of high quality materials and have overload protection to ensure reliable performance for years to come. Smart features simplify daily jewelry weighing tasks, while our battery-operated models are perfect for weighing on the go. Furthermore, you can easily connect the balance to a printer or second display.
Built-in weighing applications specifically tailored for jewelry weighing are available on every balance, e.g. density determination to measure the purity of gold and totalization for weighing sets of gemstones.
Almost all of our jewelry balances and scales are approved versions according to OIML, NTEP, etc. (model availability is country- specific).
Easy device connection makes it simple to add a printer, secondary display or even a PC. All our accessories are backwards and forwards compatible.
METTLER TOLEDO's service portfolio offers a variety of products based around uptime, performance, compliance and training, helping you to achieve top performance, as well as enhance efficiency and productivity.
The specially angled balance display is easy to read and avoids the reflections that can occur under strong, bright lights. The secondary display allows your customer to see the weight value instantly.
Strong, high-quality materials mean your jewelry balance will sit solidly on your counter top, and will not move if accidentally bumped. The robust construction ensures a long balance lifetime and ensures a sound return on your investment.
Spare parts for jewelry balances and scales are readily available at any time. If we stop production of a particular jewelry balance model, spare parts will be available for a further three years after the end of production.
For weighing gold, a jewelry balance with a readability of 0.01 g is recommended. For weighing silver, a readability of 0.1 g/1 g is recommended.
General dust and dirt on your jewelry balance can be wiped off with a damp cloth. More thorough cleaning is achieved through the use of isopropanol/ethanol (70%). Acetone is not recommended. For more information on balance cleaning, check out our balance cleaning guide.
In gold weighing, the number of carats, or karats (k), refers to the purity of the gold with 24 carat gold (24k) being the most pure. When weighing diamonds, carat is the weight unit. 1 ct is equivalent to 200 mg.
METTLER TOLEDO's carat balances and scales are ideal for weighing diamonds and gemstones as they offer higher readability that is suitable for weighing small items. The default weight unit is also conveniently set to carat.
You should check the performance of your jewelry scale regularly using a reference weight to see if it needs to be recalibrated. In addition, a jewelry balance or scale should always be recalibrated whenever it is moved to a new location.
d is the smallest division that a balance or scale can display.
e is the smallest interval on a balance or scale that can be used in a business transaction.
For example, a scale has d = 0.001 g, providing weight results to 3 decimal places. In the case that e=d, the scale can be used in business transactions measuring weight to 3 decimal places (0.001 g). In the case that e=10d, the balance can only be used in business transactions measuring weight to 10 x 0.001 g or 0.01 g.
No. It is important not to confuse the readability of the scale with the minimum weight that can be weighed accurately on the scale. The minimum weight defines the weight of the smallest item you can weigh, while still meeting your desired accuracy requirements. The minimum weight of your jewelry scale is determined at the time of installation and is checked every time the scale is recalibrated. In the following document, you can find the typical minimum weight values that you can expect for each jewelry scale.
Legal requirements for weighing equipment vary from country to country. Therefore, it is important to check the local requirements of the area in which you do business.
Jewelry balances have a special software to meet the needs of the jewelry industry. For example, they have special weighing units.
No, all of our jewelry scales have the same METTLER TOLEDO quality and accuracy. Legal for Trade scales undergo additional testing and a tamper-proof seal is added during the manufacturing process.
