Widely applied in chemical workflows, the Combi Hand-Held Measuring Device Sevengo Duo™ SG23-Fk5 is a versatile tool that offers simultaneous measurement of pH, redox, conductivity, TDS, salinity, and temperature. This device features an intelligent Sensor Management system for seamless recognition of its ISM sensors and reading in calibration data. Its pH measurement capabilities include automatic 1-, 2-, or 3-point calibration from pre-defined points and a user-defined buffer set, along with automatic end point recognition, automatic buffer recognition, and temperature compensation for reproducible results. The device comes equipped with an InLab ExpertGo-ISM pH single-rod measuring cell with an integrated temperature gauge for aqueous samples, including emulsions, suspensions, and solutions with proteins, with a pH range of 0
