SevenGo Duo pH/Ion/Cond meter SG78-FK2-K

SG78-FK2 SevenGo Duo pro is a dual-channel portable meter for simultaneous pH/ion and conductivity determination. Built for high laboratory and field demands yet simple to operate, the IP67 instrument features an illuminated, individually adapted LCD, infrared data transfer to printer or PC, and comprehensive GLP support with sensor and sample identification. Time-interval measurement with automatic storage and a memory for 200 GLP-compliant data sets streamline routine documentation. Calibration can be segmented or linear, with five-point pH calibration using six predefined buffer sets plus one user-defined set; cell constants and custom standards are freely enterable. The pH range spans −2,000 to 19,999 (resolution 0,1/0,01/0,001; relative accuracy ±0,01), mV from −1999,9 to 1999,9, and conductivity from 0,01 µS/cm to 1000 mS/cm (±0,5 % of range maximum), with linear and non-linear temperature compensation and pure-water measurement according to USP/EP. TDS, salinity and resistivity modes are also available. Supplied as a complete set from manufacturer Mettler-Toledo OnLine, the kit contains the meter, InLab Expert Pro-ISM pH electrode (2 m), InLab738-ISM conductivity electrode (2 m), calibration solutions, field case, operating instructions, declaration of conformity, test certificate and four 1,5 V AA batteries. Net weight 2,5 kg.
