PVT-230 Probe/pH Probe Accessory

Process Viscometer for Viscosity Control of Inks, Paints and Coatings

The PVT-230 Viscometer is used in printing and coating applications to maintain viscosity and pH by automatically adding the appropriate control agents. The instrument is available with an optional pH probe and control package which displays viscosity, pH, and temperature. The PVT230 is a rotational viscometer providing true dynamic viscosity measurements at defined shear rates.

• Optimizes product consistency and quality
• Provides measurement and control of viscosity
• Provides a permanent record for quality control when used with a recorder or PC
• Minimizes waste; automatic solvent additions reduce operating costs
• Ensures continuity of color value with minimum ink and solvent consumption in printing operations
• Maximizes press operating speeds
• Easy to start-up, operate and clean
• Senses/responds instantaneously
• Direct in-tank measurements
• Wetted parts are 300 series stainless steel

The controller provides control of viscosity and pH, and displays process temperature (the RTD temperature probe is built into the pH sensor). Viscosity may be displayed in cP (mPa·s) or seconds (Zahn, ISO etc.). Process condition and set point are displayed for viscosity and pH.

The controllers are equipped with relay output to operate solenoid valves, which add appropriate control agents to the working fluid; current output may be provided as an option.
