Overview

The Tu-4 Viscometer (model: TND-4G) is an instrument produced by the QIWEI brand for the measurement of viscosity in liquid conditions such as coatings. It indicates viscosity by measuring the time (seconds) required for a certain amount of sample to flow out of a specified aperture at a specific temperature, which meets the requirements of national standards.

Features

1. Brass cup body with a capacity of about 100ml and a stainless steel outflow hole at the bottom to ensure durability and accuracy 2.Geometric dimensions and inner wall asperity strictly comply with GB/T 1723 standard 3. Equipped with correction factor K (range 1 +/- 0.03) to ensure the accuracy of measurement results 4. Outflow time measurement range 0~ 150 seconds, to meet a variety of viscosity measurement needs

Principle

The coating -4 Viscometer measurement is the conditional viscosity, that is, the time for a certain amount of specimen to flow out of an outflow hole of a specified diameter (4mm) at a fixed temperature, expressed in seconds. The outflow time t (s) obtained by measurement can be converted into kinematic viscosity μ (mm ²/s) by the formula: when t < 23s, t = 0.154 μ + 11; when 23s ≤ t ≤ 150s, t = 0.223 μ + 6.0.

Standards

GB/T 1723

Notice

The correction factor K should be within the range of 1 +/- 0.03, otherwise the Viscometer needs to be replaced. • Viscometers should be regularly calibrated according to the frequency of use • The difference between the measured value of the standard viscosity liquid outflow time and the calculated value should be within +/- 3% of the calculated value
