HK-7600 Coulometric Karl-Fischer Titration Tester


HK-7600 Coulometric Karl-Fischer Titration Tester conforms to the ASTM D4377 and ASTM D4928, which is used for testing water content of crude oil is important in the refining, purchase, sale, or transfer of crude oils. Our HK-1059 is used for determine water in the range from 0.02 to 2 % in crude oils. Mercaptan and sulfide (S− or H2S) sulfur are known to interfere with this test method and determine water in the 0.005 to 0.02 mass % range, but the effects of the mercaptan and sulfide interference at these levels has not been determined. For the range 0.005 to 0.02 mass %, there is no precision or bias statement.


HK-7600 Coulometric Karl-Fischer Titration tester is controlled by the SCM, which features system fault self-diagnosis, color liquid LCD touch screen and friendly human-computer interface; the tester can deduct blank current automatically with high test result accuracy, large current background compensation function, shorten the stand-by time greatly, particular reagent failure detection function, reminds user to change the invalid reagent, improve the use ratio of the reagent greatly. The built-in multiple water content formula meets different user’s demand. Equipped with high efficient miniprinter, built-in large capacity storage, which can store 500 test records, convenient retrieval mode, user can read and print the test report expediently.
