SevenDirect SD50 pH/Ion Meter from METTLER TOLEDO

METTLER TOLEDO’s SevenDirect SD50 is a precise and versatile meter for measuring pH, ORP, and ion concentrations. It features the convenient EasyPlace sensor arm for hassle-free deployment.

Mastered in no Time

The large color touchscreen makes easy data entry and direct measurement possible. Instructions guide users through the sensor calibration process.

Tracks the Records

With each measurement, the device saves information such as the timestamp, sample, and sensor ID. Records are then automatically printed or exported.

Tough Enough

Even with sensors connected, the instrument is protected from dust and spills by a closed connector compartment and a removable cover (IP54 in use).

Electrode Arm for Efficient Operation

The EasyPlace electrode arm simplifies the process of placing the sensor into the sample or buffer container. It provides designated spots for cleaning and storage, ensuring proper sensor handling. Both vertical and horizontal movements enable accurate positioning, even with one hand.

Protect Critical Settings

A two-level user management system protects the most crucial settings. Operators can continue to customize settings for things like language and screen brightness.

Display Adapts to the Needs

Users can access comprehensive measurement data on a single screen or opt for the uFocus mode to streamline readability and concentrate solely on the results.
