Digital density meter 4340

for paper porosity measurement

The 4340N Series of Paper Porosity Densomete, manufactured by GURLEY Precision Instruments, is designed for testing the porosity and smoothness of paper, paperboard and other flat-sheet materials. This device is optimized with the textile standard and high pressure densometers. Moreover, it provides fast results to increase productivity, and can reduce unwanted waste of time. This product can be used in manufacturing, printing, testing filters, testing insulating materials applications. Combination of low, standard and high pressure Gurley Densometers and smoothness testers Our flagship instrument. The Model 4340 combines the abilities of our textile, standard and high pressure Densometers, S-P-S Testers as well as our programmable digital timers and provides a reading in seconds, thus reducing the time required to test a material. By utilizing state-of-the-art mass flow technology, the Model 4340 can accurately test both low and high flow materials traditionally tested between 0 and 50,000 'Gurley Seconds'. At the end of either an automatic or manual test, the user can then toggle between Gurley units, Bendtsen, Sheffield or Bekk equivalent units. Conform to TAPPI T-460 & TAPPI T-536-88, ASTM D-726-58 & D-202-77, APPITA/AS 1301-420, BS 5926, CPPA D-14, ISO 5636/5, SCAN P-19 & P-53. Overview The Model 4340 differs from the traditional manual Densometers in several ways. First, the Model 4340 utilizes the latest mass flow and servo-regulator technology to provide a quick, accurate test that is oil-free. Second, pneumatic cylinders insure both a consistent clamping pressure as well as an automatic test feature; which allows the user to test a
