HK-7600 Coulometric Karl-Fischer Titration Tester OverView 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-7600 is used for détermine water in the range from 0.02 to 2 % in crude oils. Mercaptan and sulfide (S-or H2S) sulfur are known to interfère with this test method and détermine water in the 0.005 to 0.02 mass % range, but the effects of the mercaptan and sulfide interférence at these levels has not been determined. For the range 0.005 to 0.02 mass %, there is no précision or bias statement. Features 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 resuit accuracy, large current background compensation function, shorten the stand-by time greatly, particular reagent failure détection 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 mini printer, built-in large capacity storage, which can store 500 test records, convenient retrieval mode, user can read and print the test report expediently. 1. - Rated Voltage: AC220V±10% 50Hz 2. - Measuring range: 3pg~150mg 3. - Resolution Ratio: O.lpg 4. - Accuracy: Water contenté lOpg (error±2) No aqueous injection Water content: 10pg~500g (error±3g) 5. - EIectrolytic speed: Maximum 2.0mg/min
