The instrument is composed of three parts: main unit, titration cup and feeding & drainage device. The Main unit is responsible for handling main functions, such as the exchange display of user interface, data measuring, titrate mode selection, parameter setup, titration control, communication and printing, etc.

The titration cup is the where actually measures water samples, including sampling port, capillary input, electrode interface, inlet of KF reagent A liquid , dryer interface, waste water liquid outlet, etc., adopts full sealed structure.

The Feeding & drainage Device's main function is to prevent users from direct contact with KF reagent, as an auxiliary device designed to simplify user operation, including drainage and feeding function of KF reagents. For example, the initial operation before measurement analysis: Suck out the solution in KF reagent A liquid bottle (solvent), through sealing pipe suck the solution into titration cup, and then start measurement analysis after the sample injection; After sample analysis many times, when the solution in titration cup accumulates to certain degree (or the titration cup solution alarm prompts), users need to operate the instrument to drain the solution inside the titration cup.

2.Instrument Operation

2.1 Introduction

HZ1200 Volumetric Karl Fischer Titrator (hereinafter referred to as the instrument) is a highly precise laboratory analyzer, which is mainly used in chemical analysis of college, scientific research institute, petrochemical industry, pharmacy, drug test and metallurgy.

2.1.1 Features of HZ1200

With new microprocessor technology, the meter can show relevant measuring methods and measuring results. It has friendly operating interface for convenience.

The meter has several titrate modes including Pre-titrate, Auto titrate, Manual titrate, Constant titrate and KF titer measurement, etc. The instrument has filling and cleaning function.

For KF reagent, the instrument has feeding, drainage, KF reagent mixing function, prevent users from direct contact with KF reagent, simplify the user operation.

The instrument supports automatic anti-overflow protection function for solution in titration cup.

The instrument supports failure detection and prompt functions for KF reagent.

The transmission system has been improved to reduce the size and noise of the meter during operation. The stirring system adopts PWM technology to adjust the speed of stirring system.

The meter has USB interface which can be connected to the computer. It is controlled by the professional software.
