Description

SG78 – SevenGo Duo pro™ pH/Ion/Conductivity

SG78. 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.

Professional Dual-Channel Meter With ISM®

SevenGo Duo pro™ combines maximum measurement accuracy and an excellent range of functions with user-friendly operation and exceptional security. SevenGo Duo pro™ meters are essential for special analyses, particularly in regulated sectors in the pharmaceutical, chemical, cosmetic and food & beverage industry. The kit versions are also well suited for outdoor use because both the meter and the sensors are watertight (IP67).
The revolutionary intelligent sensor management system (ISM®) offers the user an even greater level of security. The calibration data is stored on the chip in the sensor and is used automatically when the sensor is connected to the meter. This ensures that the meter always uses the latest calibration data.
