The BGD 180 Intelligent Touch-screen Rotothinner is a user-friendly rotary viscometer. It is designed to measure the viscosity characteristics of samples at three different shear rates (20s−1 , 44s−1, and 200s−1) and can also assess the viscosity characteristics of the same sample over varying shearing times
This instrument complies with ISO 2884-2, "Paints and varnishes - Determination of viscosity using rotary viscometers - Part 2: Disc or ball viscometer operated at a specified speed," and BS 3900 A7 standards
