Routine Dual-Channel Meter With ISM®

SevenGo Duo™ combines user-friendliness, quality and reliable measurements. The meter is designed so that a single keystroke triggers a calibration or measurement or allows accessing stored results or system settings. The kit versions are also well suited for outdoor use or use in the production area 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.
