Application:
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.
