GB7600 Digital Karl Fischer Water Content Tester TP-6A

  • TP-6A



This TP-6A water content tester adopts the global recognized classical moisture testing method - Karl Fischer Coulometric Method which is the most accurate method with low cost. With the 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.

The whole testing process is automatically controlled by this tester itself. Its auto-stirring and analyzing would be finished within 60seconds, and results would be displayed directly. Totally closed titration system avoids damage to operator from reagent. Equipped with 500ml Karl Fischer Reagent, which could test about 1000 times sample continuously, completely avoiding big deviations of other moisture testing method and thus improving quality index of products.

1. Advanced MPU auto-control system and direct A/D conversion of testing electrode data

2. Completely closed titration system avoids direct touch between people and the reagent 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 six-digit Nixie tube display, with long service lifetime, high luminance and 0.1 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. 400mA electrolysis current is automatically controlled, which greatly improves its sensitivity and accuracy.

8. Sample auto-testing and direct display of results.
