LBT 162 Intelligent Touch-Controlled Rotational Viscometer

Description

Product Introduction

The intelligent touch‑controlled rotational viscometer is an upgraded replacement for the original digital viscometer. It features a powerful 7‑inch high‑definition touchscreen with an intuitive human–machine interface, offering convenient operation and rich display information, making it a fully automated instrument for measuring liquid viscosity. Equipped with an ARM‑based processor, the device precisely controls the speed of the stepper motor and manages the entire measurement process. Under computer program control, it automatically completes viscosity measurements, with results displayed on the screen. The instrument boasts a compact design, stable performance, high measurement accuracy, and excellent anti‑interference capabilities. It is suitable for determining both kinematic viscosity and absolute viscosity and is widely used in industries such as coatings, inks, resins, adhesives, petroleum products, cosmetics, and food, as well as in research institutions.

◆ Complies with standards GB/T 2794, GB/T 10247-2008 (rotational method), GB/T 21059, GB/T 22235-2008 (rotational method), GB/T 22314-2008, ISO 1652, ISO 2555, ISO 3219, ASTM D2196, ASTM D2983, and others.

◆ 7-inch HD touchscreen, offering simple and convenient operation, directly displays viscosity, rotational speed, torque, and the maximum viscosity value that can be measured by the rotor at the current speed.

◆ Built-in high-precision electronic level; the screen directly displays the instrument’s leveling status, enabling operators to quickly and easily adjust the instrument to a horizontal position.

◆ Magnetic‑suction rotor removal and installation method reduces damage to the journal during disassembly, enhancing its durability.

◆ Highly compatible; users can perform self-calibration.

◆ Overcomes the limitation of domestic instruments, which can only perform a single sampling per rotation, by enabling multiple samplings in a single rotation.

◆ The stepper motor, driven by high‑resolution microstepping, delivers precise and smooth rotational speed; variations in AC voltage frequency do not affect the accuracy of viscosity measurements.

◆ Direct drive with a stepper motor: noise-free, easy to adjust speed, highly reliable, and free from vibration.

◆ The viscosity value is displayed as a continuous change, and an audible alarm sounds when the measurement range is exceeded.

◆ Full-range linear calibration, with a measurement accuracy of ±1.0% of full scale.

◆ For thixotropic non-Newtonian fluids, the instrument’s timing function ensures consistently reliable data.

◆ Tempered glass base, durable and easy to clean

◆ ARM-based processor, delivering faster data processing speeds

◆ Arbitrary conversion among multiple viscosity units; automatic conversion between dynamic viscosity and kinematic viscosity.

◆ Supports exporting data to an external USB flash drive.
