TT-220 Probe/pH Probe Accessory

For Open Tank Applications

The TT-220 Process Viscometer is intended for open tank applications (5-20 gallon, 20-75 liters) requiring constant viscosity monitoring and or control. The TT-220 is often used in coatings or printing applications. The TT220 is a rotational coaxial cylinder (Searle) viscometer providing true dynamic viscosity measurements at defined shear rates.

An optional sealed pH probe and controller (plus temperature sensor) is available.

• Integrates control of viscosity and pH (optional)
• Dual LED displays indicate process viscosity vs. set point and optionally pH vs. set point
• Optional RS485 computer interface
• Displays viscosity in cP, mPa·s, or orifice cup seconds
• Senses/responds continuously
• Control capability includes PID, auto-tune PID, or on/off
• User selectable high/low alarms
• Easy to start-up, operate, and clean
• Wetted parts are 300 series stainless steel

Specifications

• Viscosity Range: 15 to 50,000 cP
• Accuracy: ±1% of full scale range
• Temperature Range: -40°C to 100°C
• Output: mechanical relay or 4-20 mA

The TT-220 is also available with pH measurement/control for use in water based printing inks and coating materials, which are sensitive to pH variation. In this case the instrument measures and controls pH in addition to viscosity. Specifications are as above with the addition of pH measurement and control capability.
