Viscometer G26

The G26 is a microprocessor controller for the regulation of the viscosity of solvent based ink. The viscosity measurement is made through a vibration sensor inline with the ink piping without moving parts.
This sensor emits a frequency to the controller that processes the viscosity in seconds (cup ZAHN, FORD etc.) and, then to the solvent valve, which maintains the value according to the reference signal.

The cleaning of the viscometer is made at job end, while washing up.


Rotogravure and Flexographic presses. Solvent based ink and varnish.

Console and command screen

PC 15” touchscreen display. All colours displayed on the screen. All viscosities are displayed on a graphic bar. Save up to 10.000 different jobs. Temperature control function displayed. Error signals (no ink, no water or viscosity over tolerance).

Control G26

Rack system cabled by connectors. Installed in a cabinet. Serial communication between PC and control.

Viscometer G26-RIV

G26-RIV to install in a danger zone near the ink tank. Solvent correction through pneumatic valve. Feeding by rotary or alternative pumps. Viscosity accuracy is measured within 1%.


Control temperature by G90 heat exchanger. HMI 4,3” – 9,7” touch screen display. Magnetic filter G70.

Maintenance and cleaning

At the end of the job, the cleaning of sensors is made simultaneously with the press ink cleaning system. No mechanical parts or moving components.
