Combi table-top multimeter SevenDirect™ SD23 Basic

From Mettler-Toledo

Fits to / Accessories

For determining pH/Redox and conductivity/salinity/TDS.

Single/dual mode: Single measurement or simultaneous measurement of pH and conductivity is possible
Large colour touchscreen (7″) for straightforward data input and direct measurements
Simple and intuitive operation. On-screen instructions provide step-by-step guidance through the programs (e. g. sensor calibration).
Screen display can be adjusted for specific requirements. Full-screen mode displays all information, while the details screen only shows the most important measurement information with large digits.
Calibration can be performed with predefined and user-specific buffers and buffer groups. Calibration memory with optional sensor lock setting available. Quality of the most recent sensor calibration shown directly via pH sensor symbol. Verification mode enables checking of the current sensor status.
Electrode arm can be operated easily with one hand. Simple and safe electrode handling via specific positions for cleaning and storage. Precise positioning via vertical and horizontal movements.
Traceable documentation. With each measurement, data such as the timestamp or sample and sensor ID is saved and automatically printed or exported.
Two-level user management (administrator, operator) prevents unwanted changes to device settings
Internal measurement data memory: save by pressing a key or with time-controlled measuring intervals
Intelligent Sensor Management (ISM^®) for automatic recognition of ISM^® sensors and reading in calibration data

Delivery incl. electrode holder and protective casing.

Without sensors, please order separately.
