Name: Precision Balance MA303
Brand: Mettler Toledo

Simple Operation

Touch control, simple menus, guided applications, automatic calculations, and easy results documentation make weighing a breeze.

Built to Last

The strong metal base and tough outer housing make these balances highly resistant to aggressive chemical agents as well as easy to clean.

Efficient Performance

With proven weighing technologies and built in adjustment using the internal test weights, you can trust your results to be consistent and precise.

Multiple Interfaces

Thanks to the USB-A and RS232 interfaces, you can transfer your weighing data quickly and without error to a printer or a PC or connect to a USB storage device for simple data transfer.

Touch Operation with LCD Display

The bright LCD screen provides excellent readability, while the glass surface resists wear and tear and is easy to clean. The touch keys make it simple to operate the balance and navigate through the menus in the user interface.

Built-In Adjustment Procedure

With just one keypress, you can trigger the balance to perform an adjustment procedure using its own internal test weights. This simple process helps to ensure consistently accurate weighing results.

Passcode Protection

Altering balance settings requires a password, preventing unauthorized or accidental changes. You can therefore be sure that all balance operators use the same settings and that your processes are consistent.

Standby Mode

When you’re not using your balance, save energy by putting it in standby mode. You can also set it to enter standby automatically after a predefined number of minutes. What's more, it’s ready for use when you exit standby—no warm-up is necessary.
