The METTLER TOLEDO SevenDirect SD23 meter is a precise and adaptable instrument that measures pH and conductivity independently or simultaneously. It comes with an EasyPlace sensor arm.
Mastered in no Time
A large color touchscreen provides direct measurement and easy data entry. Instructions guide users through the sensor calibration process.
Tracks Customer Records
The instrument stores data like timestamps, samples, and sensor ID with every measurement and prints or exports records automatically.
Tough Enough
A closed connector compartment and replaceable cover keep the instrument safe from dust and spills, even with sensors attached (IP54 in use).
Electrode Arm for Efficient Operation
The EasyPlace electrode arm simplifies the positioning of the sensor in the sample or buffer container. Specific locations designated for cleaning and storage promote proper sensor handling. Vertical and horizontal movements enable precise positioning, even when using only one hand.
Protect Critical Settings
A two-level user management protects the most important settings. Operators retain the flexibility to individually set preferences like language and screen brightness.
Display Adapts to Customer Needs
You can access comprehensive measurement details on a single screen or opt for uFocus mode to enhance readability by concentrating solely on the result.
Two Parameters in One Device
Measure both pH and conductivity using a single instrument, either simultaneously or separately, depending on the application's specific requirements.
