Our diamond scales and carat scales offer unparalleled precision for weighing precious gemstones. With high-quality materials, overload protection, and smart features, our scales ensure reliable and convenient performance. Plus, our battery-operated models are perfect for weighing on the go, and you can easily connect our balances to printers or secondary displays for effortless record keeping.
Built-in weighing applications specifically tailored for diamond weighing are available on every balance, e.g. density determination of diamonds.
Almost all of our diamond scales and balances 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 scale 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 diamond weight value instantly.
Strong, high-quality materials mean your diamond scales 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.
We support and service your measurement equipment through its entire life-cycle, from installation to preventive maintenance and calibration to equipment repair.
In general, diamonds are weighed in carats to 3 decimal places so the readability required is 0.001 ct. For very small diamonds, METTLER TOLEDO also offers balances with a carat readability of 4 or even 5 decimal places.
When weighing diamonds, periodic calibration is necessary to ensure ongoing accurate and reliable results. Calibrating your diamond weighing instrument will ensure that it reaches standards such as ISO, GMP/GMP, IFS and BRC. Documented calibration procedures verify the quality of measurements, and should be performed regularly throughout the balance’s lifetime. Calibration should not be confused with adjustment and must be repeated after adjustment/repairs.
METTLER TOLEDO diamond scales are made from high-quality, chemically resistant materials and can therefore be cleaned with a commercially available, mild cleaning agent and a damp cloth or soft paper tissue. Use common cleaning agents such as 70% ethanol or isopropanol, or mild detergents. The weighing pan and balance base are made of stainless steel that is robust and chemically resistant, with the exception that it is not compatible with strong acids. Acetone should not be used, even for highly sticky substances, as it is not compatible with plastic handles, glued parts or the screen.
JET carat scales have 3 interface ports — USB host, USB device and RS232 — and are easy to connect to an internal network via the built-in PC Direct function. In addition, JET carat scales offer Bluetooth connection via the optional Bluetooth adapter.
