7827 High Performance Viscosity Meters
The 7827 digital viscosity meters is used for quality and analytical measurements where kinematic viscosity at line and reference temperature are required to be measured. The essential accuracy and speed of response makes this the first true viscometer solution for process measurement. When 7827 digital viscosity meters are used in conjunction with 795x Series Signal Converters, a variety of referral methods are avialable to compute the viscosity at the reference temperature from the viscosity measured at the process conditions.
