Now you can quickly and easily check the viscosity of any oil…on site. The Visgage® is inexpensive and easy to use…no stop watches or thermometers are required. This simple test method has been used for seven decades in thousands of industrial plants, maintenance shops, and at hundreds of remote equipment locations. Checks engine oils, lubricants, and hydraulic fluids. Special models are available for water glycol.

The principle of operation is simple and is based on comparing the viscosity of a sample of oil with an oil of known viscosity. The viscosity reading is made in either saybolt universal seconds at 100°F or centistokes at 40°C at room temperature. No calculations are necessary. An accuracy of 95% or better is easily achieved when making tests, and careful operators can test to ±1% accuracy. More visgages are in use throughout the world than any other type viscometer, and for very good reasons - better accuracy and easier operation. Unless you are willing to pay a very high price for viscosity tests, your operator in the field can consistently test as accurately as most commercial laboratories, and much faster - especially when you need to know results right now.
