DWHVT-II ASTM D5867 ASTM D2812  HVT High Volume Instrument High Volume Fiber Tester DWHVT-II Micronaire value, maturity index, length  


Application: 


 


DWHVT-II HVT High Volume Instrument is used to determine the cotton fiber properties, such as Micronaire value, maturity index, length including upper half mean length (UHML), uniformity index (UI) and short fiber index (SFI), fiber strength in g/text and elongation, moisture content, color (Reflectance Rd, degree of yellowness +b) and color grade (American upland cotton color grade CG) and real trash content (%).

Compact and ergonomic model embedded with microcomputer controlled technology for rapid measurement;


Less space occupation, less weight and comfortable and SS stop work space;


3  Calibration by USDA and any other international calibration cotton;


Advanced trash separation by buoyancy separation technique by the use of air currents;


Precise and rapid measurement with single specimen feed;


6 Parallel as well as simultaneous operations ensure faster testing;


More tests can be performed under combined tests mode;


Since it is measuring real trash content (%), it will take 12 minutes for 50 gram sample size;


Flexible report options like date wise, lot wise, cotton type wise as well as consolidated reports;


10  Automated Fiber Comb Sampler for better sampling repeatability and avoid operator influence.
