product details
l supports the measurement of moisture content in the full range including volumetric method and coulomb method to meet the measurement needs of different users of constant moisture and trace moisture;
l dot-matrix lcd display, key operation, simultaneous control or separate control by computer chinese software; real-time display of relevant test methods and test results;
l "conversational" operation steps to easily complete titration settings and process operations;
l pollution-free measurement and analysis process: anti-leakage device and waste bottle anti-suckback device; automatic liquid inlet, liquid discharge, kf reagent mixing and automatic cleaning functions, anti-titration cup solution overflow protection function; to prevent users from directly contacting kf reagents, to ensure the safety of measurement and use personnel and the environment;
l support pre-titration, automatic titration, manual titration, constant titration, kf titer determination and other titration modes to meet the analysis of different types of samples;
l supports a variety of burette types, and supports re-calibration of burette coefficients;
l users can choose mg, mg/l, %, ppm and other measurement result units as needed; the instrument supports glp specification, supports storage of 200 sets of constant and trace moisture measurement data; supports data storage, deletion, viewing, printing or output;
l with power-off protection function and kf reagent failure detection and reminder function;
l support rs232 serial printer to print measurement results;
l support firmware upgrade and software upgrade, allowing function expansion.
