LCH Color Screen Brookfield Rotary Viscometer
The Whirl-pak LACHOI LCH Color Screen Brookfield Rotary Viscometer is a high-precision digital instrument designed for measuring the dynamic viscosity of Newtonian and non-Newtonian liquids. Featuring a high-definition TFT color display and advanced microcomputer control, it provides real-time data on viscosity, torque, and temperature, making it a powerful alternative to traditional analog viscometers for quality control and R&D
Description
Description
The LACHOI LCH Color Screen series utilizes the classic Brookfield rotational principle—rotating a spindle in a fluid and measuring the torque required to overcome viscous resistance—but upgrades the experience with modern digital technology. The full aluminum housing ensures high durability and electromagnetic shielding, while the synchronous damping system inside provides stable, whisper-quiet operation.2
This viscometer is widely used in industries such as food (sauces, syrups), cosmetics (creams, shampoos), oil and petroleum, and chemicals (paints, resins) where precise flow characteristics are critical.
Key Features
High-Resolution TFT Color Screen: The intuitive interface displays viscosity (3$mPa·s$ or 4$cP$), torque percentage, spindle number, rotational speed, and temperature simultaneously.5
Precision Stepless Speed Regulation: Offers flexible speed control (typically 0.1 to 200 RPM), allowing users to find the exact shear rate needed for non-Newtonian fluid analysis.6
Wide Measurement Range: Supports a broad spectrum of viscosities from thin solvents to thick pastes (ranges vary by model: LV, RV, HA, or HB series).7
Built-in Temperature Monitoring: Includes a high-sensitivity RTD temperature probe to ensure all viscosity readings are indexed to a specific temperature, which is vital for accuracy.
ARM Technology & Linux System: The internal processor enables fast data acquisition and complex functions like time-to-stop, time-to-torque, and automatic range scanning.8
Data Export & Connectivity: Equipped with an RS232 interface and often Bluetooth capability, allowing for direct connection to a micro-printer or a PC for detailed curve analysis and report generation.9
Safety & Stability: Features a digital leveling system to ensure the instrument is perfectly upright, along with “over-range” alarms to prevent damage to the internal spring and sensors.
Aluminum Build: The robust full-aluminum shell protects the delicate internal electronics from harsh laboratory environments and reduces vibration
