Density meter Excellence D6 - Overview - METTLER TOLEDO

Density meter Excellence D6

Accurate, Intuitive, and Modular.Best in class for highest accuracy: The Excellence D6 Density Meter offers fast measurements with automatic temperature control from 0 to 95°C, and accuracy of up to 0.000005 g/cm³. Delivered with a syringe holder for precise sampling.

Simple One Click™ Operation

The One Click™ user interface enables users to start a complete workflow with one click including sampling, measuring, rinsing, drying, and SOPs.

Smart Error Detection

Measurements can be observed in real time via video, and sampling errors can be avoided with the automatic bubble detection algorithm.

Result limits

Measurement limits can be set for color-coded pass/fail information for accepted and rejected samples.

Automatic Temperature Control

The integrated Peltier temperature control quickly heats up or cools down the measurement cell, maintaining the sample reliably at the desired temperature.

User Management

Instrument settings can be personalized with shortcuts and the selected operator language. The user management system allows different levels of access to be defined, protecting critical data.

Seamless Modularity

A refractive index cell can be combined with the Excellence density meters to provide a space-saving system for applications where both density and refractive index values are required.

Status Light

The status light of the instrument shows if it is ready for a measurement (green), busy (blinking), or waiting for operator action (orange).

Automated Sampling, Rinsing and Drying

Automating workflows saves time, reduces costs and increases safety. The Excellence density meters are compatible with a portfolio of autosamplers including solutions for single or multiple samples, and samples which are viscous or solid at room temperature

Upgradable System

The Excellence density meters can be upgraded into a dedicated automatic multi-parameter system combining density, refractive index, pH, color, and more to save time, increase data quality and prevent any alteration of samples between individual analyses.
