The BGD 180 Touch-screen Rotothinner is a user-friendly rotary viscometer designed for simplicity and accuracy in viscosity measurements.
It is utilized to assess sample viscosity characteristics under three distinct shearing rates (20S-1, 44S-1, 200S-1), and can also determine viscosity variations over time under constant shear. This device adheres to 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.
