GDJ-1B Digital Rotational Viscometer
Characteristics and Advantages:
ed and made as per ISO 2555 and JJG-2005
2.with high subdivision,driver controlled stepper motor,so it can adjust speed continuously,accurately and conveniently.
3.adopts a LCD display,i can show the viscosoty of samples(mPa.s),spindle No.,speed(RPM) and the Max.viscosity value the instrument can measure with selected spindle under the current speed.
4.spindle are made of stainless steel of AIS314.
5.if purchase 0#spindle,it can determine low viscosity samples.
6.if purchase small sample adapter it is designed for use few samples.
