FTWS-810 Luxury type Automatic Karl Fischer Water Content tester is used for Coulometric water determination of the trace moisture content in solids, liquids, and gases with different properties according to Karl Fischer as per ASTM D1533, ASTM D6304, GB/T1600, GB7600, B/T 18619.1, GB/T 11133, SH/T 0246, SH/T 0255, etc.
Karl Fischer Coulomb titration is the most reliable method to detect trace moisture for different substances, which was utilized successfully by FTWS-810 trace moisture titrator.
This trace water tester, with its successful application of the method and utilization of computer aided control system, enables a fast determination and higher accuracy while titrated findings are directly displayed on a digital screen. Its self-diagnosis for fault and information display functions help to achieve a more efficient automatic operation.
This Karl Fischer Oil Trace Water Content Analyzer adopts new processor and circuit, excellent low-power consumption. Use measuring electrode signal as the criterion for the end of electrolysis. The stability and accuracy are the critical factor of effect on measurement accuracy. Due to use advanced components and method, make it possible to accurately measure electrode signal and further understand the characteristics of electrolyte. Accurately measure the trace water in liquid, solid and gas, applied to electric power, petroleum, chemical, pharmaceutical and food industries.
