Introduction
This meter adopts the global recognized classical moisture testing method—Karl Fischer Coulometric Method. This method is the most concentrated and accurate method, with advantages of high accuracy and low cost. As a universal standard and analyzing method, it can quickly analyze the moisture content in liquid, solid and gas and directly display testing results, with testing range from 0.0001%(1ppm) to 100%. Therefore, this testing method has been widely used in institutions and enterprises of petroleum, chemical industry, power, pharmaceuticals, pesticide, railways, research, etc.
Features
1).Adopts advanced MPU auto-control system, direct A/D conversion of testing electrode data
2).Completely closed titration system avoids direct touch between people and agent as well as influence of environmental humidity.
3).Auto-control and compensation of electrical current via MCU contributes to quick balance of reagent.
4).Highlighted Nixie tube display, with long service lifetime, high luminance and microgram’ sensitivity.
5).Stirring speed is adjustable and steerable via buttons; breakdown can be self-checked via buttons.
6).Electrolysis and testing indicator lights indicates testing status.
7).500mA electrolysis current is automatically controlled, which greatly improves sensitivity and accuracy.
8).Advantages of sample auto-testing and direct display of results.
