ZDY-504 constant moisture titrator

Features:

1. Support the measurement of the full range of moisture content including volumetric method and coulometric method to meet the measurement needs of different users of constant moisture and trace moisture;

2. Dot matrix LCD display, key operation, computer Chinese software control or separate control; real-time display of relevant test methods and test results;

3. "Dialogue" operation steps to easily complete titration settings and process operations;

4. Non-pollution measurement and analysis process: anti-leakage device and waste bottle anti-suckback device; full automatic liquid inlet, liquid discharge, KF reagent mixing and automatic cleaning functions, anti-titration cup solution overflow protection function; prevent users from directly contacting KF Reagents to ensure the safety of staff and the environment for measurement and use;

5. Support multiple titration modes such as pre-titration, automatic titration, manual titration, constant titration, KF titration determination, etc. to meet the analysis of different types of samples;

6. Support multiple burette types and calibrate burette coefficients;

7. The user can select various measurement result units such as mg, mg/L, %, ppm, etc.; the instrument supports GLP specifications, supports the storage of 200 sets of constant and trace moisture measurement data; supports data storage, deletion, inspection, Print or output;

8. With power-off protection function and KF reagent failure detection and reminder function;

9. Support RS232 serial printer, print measurement results;

10. Support firmware upgrade and software upgrade, allowing function expansion.
