Coulometric Karl Fischer Moisture Analyzer Coulometric Karl Fischer Liquid Determinator

Coulometric Karl Fischer Moisture Analyzer     Coulometric Karl Fischer Liquid Determinator

Instrument Introduction

The coulometric Karl Fischer moisture analyzer adopts a 5.7-inch capacitive high-definition color touch screen. The operation interface is simple and intuitive, with a navigation-style operation method, making it easy to get started. Its unique circuit and program design features high precision, fast electrolysis speed, short equilibrium time, accurate blank subtraction, and reliable analytical results. The measurement accuracy of this instrument can reach the ppm level, making it suitable for measuring various liquid products with low moisture content.

Product Features

1. Strong environmental adaptability, with precise, accurate, and stable measurement results

The full digital intelligent control measurement during the electrolysis process, precise background current deduction, and complete elimination of the influence of environmental air humidity and stirring rate;

Exclusive use of real-time dynamic impedance method to determine the titration endpoint, resulting in more accurate measurement results;

It can set the equilibrium point (titration endpoint) to ensure the wide adaptability of the instrument to different sensitivity reagents;

2. Built-in multiple testing methods, making the testing process simpler

The carefully refined eight concentration calculation formulas cover most of the moisture measurement standards in China and abroad, and six testing methods can be selected to meet various needs;

Measurement result storage and query function: It can store 500 sets of measurement data, and comes with a built-in printer for immediate query and printing;

3. High reliability

Core components use industrial-grade data conversion chips from the United States, with excellent linearity and long-term stability;

The used components and key parts are all from international first-line brands:

IC: ANALOG, TI, ISSI, CY, SAMSUNG, Toshiba, etc. for new industrial-grade ICs

Capacitors: Murata; Inductors: TDK, Murata; Solder: Alpha; Connectors: Molex, HRS, Omron, etc.

4. Simple operation

Navigation-style menu design, functions are clear at a glance, capacitive touch screen operation, as convenient as operating a mobile phone, different from the resistive screens of other instruments, it is more convenient to use and the click is more accurate.

5. Rich display content, clear measurement process

It simultaneously displays water content, measurement time, ppm, percentage content, electrolysis current, potential, system time, etc., making the experimental process clear and enabling timely detection of problems;

6. Multiple test result units can be selected, suitable for different samples

Measurement results are automatically calculated, including percentages, ppm, mg, etc.; in line with GLP experimental records, including measurement time, moisture content, percentage, system time, etc.
