Caulking Viscometer: CV-100

Perfect Instrument for Highly Viscous and Hard-to-Measure Materials!!

The CV-100 Caulking Viscometer is a compact but heavy-duty instrument that is ideal for highly viscous and hard-to-handle material on the production floor or in the QC lab.  Like all other SBS viscometers, the CV-100 combines economy, ease of operation, accuracy, reliability, and versatility.  High quality of instrument guarantees reliable performance for a long life. Small sample size and temperature control are also available.

The Caulking Viscometer consists of a support stand and a disposable sample tube filled with the liquid whose viscosity is to be determined. Viscosity of the sample is determined by measuring the falling time of a controlled needle through a predetermined distance of the fluid held in a sample tube. The falling time is measured automatically by means of Hall sensors and a magnet in the weight holder (CV-100), laser sensors (CVa-100) or manually (CVm-100). For Non-Newtonian fluid, a computer program is available from SBS.
