Viscometers
BYK-Gardner · byko-visc DS — in-can paint viscosity
Krebs Stormer viscometer
A digital Stormer viscometer that automatically calculates in-can paint viscosity in Krebs units, grams, or centipoise, simulating real stirring conditions at a constant 200 rpm directly inside standard paint cans.
BYK-Gardner · byko-visc RT — rotational viscometer
Rotational viscometer
The most versatile model in the byko-visc family. A rotating spindle is immersed in the sample; the torque required to turn it is proportional to viscosity, measured by a precision spring mechanism across a wide measurement range.
BYK-Gardner · byko-visc CP — absolute viscosity
Cone & plate viscometer
Determines absolute viscosity from sample volumes under 2 mL using fixed cone geometries and constant shear rates, ideal for non-Newtonian fluids and high-shear processes such as spraying or rolling.
BYK-Gardner · Gardner-Holdt — tubes A5 through Z10
Bubble viscometers
A proven method for the rapid determination of kinematic viscosity in resins, varnishes, and oils. The time for an air bubble to rise is directly proportional to viscosity. Sealed glass tubes with a 15-year shelf life and no orifices susceptible to clogging.
BYK-Gardner · Flow cups
Ford · DIN · Zahn — dip, flow cups
Simple, robust instruments for the rapid determination of efflux time. Available in certified versions with full NIST or PTB traceability, covering a wide viscosity range for low- to semi-viscous liquids. Ideal for workshop or inline production control.
BYK-Gardner · Stands, standards & accessory kits
Accessories
Stands, calibration standards, and accessory kits that complete every measurement setup — from cup leveling and temperature control to spindle storage and tube replacement.
