产品概述：
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, from as low as 0.1 sec-1to as high as 600 sec-1.
特点和优势：
LED displays indicate process viscosity 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
Can measure at API-defined shear rate of 511 sec-1, or “LSRV” drilling mud shear rate of 0.15 sec-1
