Fully automatic characteristic viscosity meterBased on capillary method and automation control technology, viscosity is calculated by measuring the flow time of liquid in the capillary. The core process includes:

Constant temperature control: The double-layer bath design combined with high-precision temperature control modules ensures stable testing temperature and eliminates the influence of temperature on viscosity.

Automatic sampling and cleaning: The peristaltic pump or vacuum system accurately sucks in the sample to the capillary scale line, and after testing, it automatically injects solvent for cleaning to avoid cross contamination.

Optoelectronic detection and data acquisition: Infrared photoelectric sensors monitor in real-time the time when the liquid level flows through the upper and lower scale lines of the capillary tube. The system automatically records multiple flow times and takes the average value. Combined with the capillary constant, it calculates the kinematic viscosity or viscosity number.

Intelligent calculation and output: The built-in algorithm automatically calculates parameters such as intrinsic viscosity and viscosity average molecular weight based on preset formulas, and the results can be exported to Excel reports or printed test reports.

This device eliminates errors caused by manual operation by accurately controlling temperature and timing, and the repeatability of the results is much better than manual methods. The entire experiment does not require manual supervision, allowing for continuous testing of bulk samples, greatly improving testing efficiency and reducing the labor intensity of operators.
