A range of dual channel portable meters for measuring 2 parameters at a time out of pH, ion concentration or dissolved oxygen (DO)
The SevenGo Duo Pro instruments are easy to use, offer the highest possible accuracy and provide great functions and security features not found in other portable instruments. In addition to the many security features the SevenGo Duo pro instruments also have ISM. This ensures that the correct and most up-to-date calibration of the connected sensor is always used for the measurement.
Dual-channel instrument for the determination of pH, mV, rel. mV, ion concentration and dissolved oxygen.
5 point pH calibration is possible, with a choice of 7 predefined and one user-defined buffer sets
Data storage for 500 GLP data records with time/date, sensor ID and serial number and user and sample IDs
Contact free IR communication
Intelligent Sensor Management (ISM)
Connect to printer or PC for output of data with GLP compliance
PIN protection - the instrument offers separate PIN protection functions for operating the device, for accessing general system settings such as the date and time, and of the deletion of data records.
ISM Intelligent Sensor Management - a sophisticated safety concept that leaves nothing to chance. The instrument automatically detects the connected sensor and uses the most up-to-date calibration data stored on the sensor chip.
Monitoring limit values - you can define your own limit values. If the actual values fall above or below the limit values a warning appears on the display and on the GLP printout.
Acoustic Signal - you can activate an acoustic signal to clearly announce the appearance of warnings on the display, the pressing of buttons and when a stable end-point has been reached.
IP67 Watertight and dustproof - making the instrument equipped for the most adverse usage conditions. The 6 indicates it is completely dustproof, while the 7 indicates it is watertight for up to 30 minutes at a depth of 1m
GLP Compliance - all measurement relevant information (such as the time and date, alphanumericsample, user and sensor IDs, sensor serial numbers and any warning messages) are stored for each measurement and can be printed on each printout.
PC Software available - LabX direct pH, the user-friendly PC software archives your results quickly and reliably. It enables the easy transfer of data from SevenGo Duo pro to an open application such as MS Excel. If required, the values can automatically be displayed graphically in the delivered MS Excel templates.
Barometric pressure correction - when testing dissolved oxygen, the air pressure is measured using the integrated barometer. The instrument then automatically compensates for any deviations in the air pressure, thus increasing the reproducibility of results.
