STM-IV  ASTM D562 Stormer Viscometer

Basic performance
Stowe’s viscometer STM to IV is a dedicated to measure the paint, coatings, etc (i.e., KU) values for the unit with the Krebs fluid viscosity test instrument.Through function keys, can be displayed on the blue backlit LCD screen circulating Krebs units (KU), g (gm) and cP (cP) as the unit of viscosity values.
This instrument adopts 16-bit microprocessor core control circuit, paddle rotate the rotor to the rotating speed of 200 r/min, the resistance moment in the current body directly by the computer into a KU values and display on the screen, with reference to ASTM D562 industry standard, can be carried out between KU, gm, cP transformation.
