Name: Analytical Balance MR304
Brand: Mettler Toledo

Perfect for All Environments

These balances deliver consistently accurate results whether you’re weighing in a busy lab or in the challenging conditions of the factory floor.

Easy Integration

Multiple interfaces and MT-SICS commands make it simple to connect your MR balance to PLC and MES systems as well as other lab instruments.

Designed for Your Convenience

Advanced functions, such as automatic adjustment and guided leveling, simplify weighing, while smooth surfaces and rounded edges make cleaning easy.

Easy-to-Clean QuickLock Draft Shield

The draft shield has been cleverly designed with fast-release QuickLock glass panels that can be quickly removed without tools and without moving the balance. The drip tray simply lifts out and all parts are dishwasher-safe.

Multiple Interfaces

The built-in interfaces support error-free data transfer to a PC, peripheral devices, or local networks. Drop-to-cursor functionality is a simple solution that lets you send results to a spreadsheet on your PC without additional software.

User Management

By setting up different user groups and profiles, operators see just the functions and applications they need to carry out their tasks, simplifying processes and reducing errors. Passcode protection prevents settings from being modified accidentally.

Automatic Internal Adjustment

To ensure ongoing accuracy, you can set the balance to perform an adjustment automatically using the internal test weights. The adjustment can be performed at a scheduled time or whenever the balance detects a change in the ambient temperature.

Power-Saving Mode

To save energy and costs, as well as protect the environment, you can configure when your balance will automatically go into its ultra-low power mode, for example overnight and at weekends. It will also warm up to be ready for work at the time you choose.
