DRK-504Coulomb moisture meter
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.
