7829 Visconic High Performance Industrial HFO Viscosity Meters
The 7829 Visconic Viscosity Transmitter is used for the measurement and control of on-line process viscosity applications. It simultaneously measures real-time viscosity, density and temperature and can be configured to output either dynamic or kinematic viscosity. 7829 Visconic Viscosity Meters build upon the proven performance of the 7827 Digital Viscosity meters and their essential accuracy and speed of response. 7829 Visconic Viscosity Transmitters are stand-alone instruments with two integral 4-20mA outputs and a Modbus RS485 communications port as standard.
In similar fashion to the 7827 Digital Viscosity meters, the 7829 Visconic Viscosity Transmitters are vibrating element meters that have many advantages over capillary, orifice and rotational viscometer types.
