Description
SG78-ELK SevenGo Duo pro is a dual-channel meter kit for pH, ion and conductivity measurement in professional laboratory and field environments. The SevenGo pro platform provides a large data memory for detailed GLP protocols, an infrared interface for transfer to a printer or PC, a backlit display and extensive parameter-specific functions, with IP67-oriented handling for demanding yet simple operation. Capabilities include timed interval measurement with automatic storage, 200 GLP-compliant data sets, segmented or linear calibration options, five-point calibration with six predefined and one user-defined buffer set, user-definable standards or cell constant, linear and non-linear conductivity temperature compensation, and pure-water measurement per USP/EP. pH covers −2,000 to 19,999 (resolution 0,1/0,01/0,001; relative accuracy ±0,01); conductivity 0,01 µS/cm to 1000 mS/cm (±0,5 %); TDS 0,01 mg/L to 600 g/L; salinity 0,00 to 80,00 ppt; resistivity up to 100,00 MΩ·cm. This complete set from manufacturer Mettler-Toledo OnLine includes the instrument, InLab Expert Pro-ISM pH electrode (2 m), InLab738-ISM conductivity electrode (2 m), calibration solutions, operating instructions, declaration of conformity, test certificate and four 1,5 V AA batteries.

Questions about SevenGo Duo pH/Ion/Cond meter SG78-EL-K
What is this article?
SevenGo Duo pH/Ion/Cond meter SG78-EL-K is the article on this page. Luminix Health distributes Mettler-Toledo OnLine for laboratory use. It sits in Conductivity meters & cells, inside pH & electrochemistry, in Lab instruments.
A conductivity meter and its cell measure how well a solution carries current. The cell constant is the geometry that converts conductance to conductivity, and it is calibrated with a standard. Temperature compensation matters because conductivity rises with temperature.
A pH meter is a voltmeter on a glass electrode. The voltage tracks hydrogen-ion activity, and the electrode is converted to pH only after it is adjusted with buffers of known value. Conductivity measures how well a solution carries a current, which for dilute salts tracks concentration. Dissolved oxygen and titration are further electrodes on the same idea: a sensor, a standard, and a reading that is only as fresh as the calibration. Buffer values and chemical identity sit on PubChem. Accreditation of the calibration laboratory is the field of BELAC and EURAMET.
Which category should I open next?
