Instrument Introduction
The GV20K Karl Fischer Coulomb moisture analyzer adopts a 5.7-inch capacitor high-definition color touch screen, which is effortless and easy to operate like a mobile phone. The operation interface is simple and intuitive, and the navigation based operation mode reduces learning costs and makes it faster to get started. Unique circuit and program design, with advantages such as high precision, fast electrolysis speed, short balancing time, accurate blank deduction, and reliable analysis results.
Not affected by the environment, automatic drift monitoring
The system automatically detects environmental drift and can accurately deduct it, ensuring that the moisture detection results are not affected by the environment and mixing speed;
Connecting the Karl Fischer oven can also automatically detect and deduct moisture in the carrier gas, further reducing the requirements for the carrier gas and lowering user usage costs;
Multiple endpoint judgment methods, suitable for various reagents
Built in multiple endpoint judgment methods: relative drift; Relative drift+time; Measure potential+relative drift; Multiple endpoint judgment methods such as measuring potential and time allow users to choose the appropriate endpoint judgment method based on the environment and sample conditions.
Using dynamic drift algorithm to determine the endpoint, it is not affected by the environment and can be used with confidence even in high temperature and high humidity areas;
The endpoint potential can be set, suitable for different manufacturers and models of Karl Fischer reagents.
The system has multiple built-in methods, and result and units can be customized
The system has 5 built-in methods and 8 formulas, suitable for various solid, liquid, gas and other samples;
Automatic calculation of measurement results, including percentages, ppm, mg, etc; GLP compliant experimental rec
ords, including measurement time, moisture content, percentage, system time, operator, etc;
Carefully select various industrial grade imported components to ensure the reliability of the instrument
All internal components are imported industrial grade components from major manufacturers to ensure the stability and reliability of the instrument.
Capacitive touch screen makes navigation menu operation more convenient
The instrument adopts a capacitive touch screen, which is different from traditional resistive touch screens, with more sensitive touch and simpler operation;
Navigation style menu, clear function options, easy to use instrument.
Display more comprehensive and intuitive content
Simultaneously displaying water content, measurement time, PPM, percentage content, electrolysis current, potential, and system time online, the experimental process is clear at a glance and problems can be detected in a timely manner.
Electrolytic current stepless regulation, test results can be calibrated
The electrolysis current is 0-500mA, customizable and adjustable, with a maximum of 500mA and an electrolysis rate of up to 2.8mg/min.
The test results can be automatically calibrated by filling in the correction factor based on the calibration results.
