The SevenDirect SD20 is a precise and adaptable pH and ORP determination meter. Its EasyPlace sensor arm provides added convenience.
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 placing the sensor in the sample or buffer container. Appropriate locations for cleaning and storage aid in proper sensor handling. Precise positioning is made easier with vertical and horizontal movements, even with one hand.
Protect Critical Settings
A two-level user management system protects the most crucial settings. Operators are free to customize settings such as language and screen brightness.
Display Adapts To User Needs
Users can view all measurement data in detail on a single screen or utilize the uFocus mode to focus solely on the result, enhancing readability.
