Features
SevenGo Duo pro™
Professional portable watertight (IP67) dual-channel meters with data memory, infrared interface for data transfer to a PC or a printer, bright backlighting and extensive GLP support - ideal for special requirements in regulated sectors or for measurements under extreme conditions.
SevenGo Duo™
Watertight (IP67) portable dual-channel meters for routine pH measurement with a large display, data memory and indication of the electrode status - ideal for applications that require a high-quality meter with exceptional performance.
Intuitive and Easy Operation
Designed in such a way that a single keystroke triggers a calibration run, measurement or review of stored data.
Intelligent Sensor Management (ISM®)
ISM® leaves nothing to chance! Calibration data and history are stored in the sensor and transferred automatically upon connection to the meter.
Ergonomic Masterpiece
Fits your hand perfectly, regardless of whether you are right- or left-handed. Your thumb can reach all buttons – easy to operate.
