QXD Fineness Gauges produced by our institute is based on the specification of the special identification regulations of measurement instruments for "Fineness Gauges" issued by former Ministry of Chemical Industry. They are applicable to determine the fineness of grind for the pigments and other particles dispersed in paints and pigmented pastes.
Main Technical Parameters
1. Types：QXD～0 QXD～1 QXD～2 QXD～3 QXD～25 (double channels)
2. Range of measurements：0～25μm 0～50μm 0～100μm 0～150μm 0～25μm
3. Graduations：2.5μm 5μm 10μm 10μm 2.5μm
4. Overall dimensions：
Single channel:170×50×12mm（length by width by height）
Double channels：175×65×13mm（length by width by height）

Impact Tester produced by our company is in accordance with the specification in National Standard GB/T 1732-93 “Determination of paint film resistance to impact” and the practical requirement of mechanical construction. The operation principle of the impact tester is by means of a weight that drops down from a specified height and impacts a painted panel under test to result in its rapid deformation, and the film resistance to impact is then attained from observing the film whether cracked or peeled off.
Main Technical Parameters：
1. Height of impact: 0-50cm
2. Hammer weight: 1000±1g
3. Diameter of steel ball on the punch end: Φ8mm
4. Overall dimension: 250×150×820mm (length by width by height)
5. Net weight: 11Kg

QBB Density Cup produced by our institute is in accordance with the specification of National Standard GB/T6750-86 "Paints and Varnishes-Determination of Density" and the practical requirement of mechanical construction. It is applicable to determine the density for various coatings, supplementary materials, oils and related materials.
Main Technical Parameters
1. Cup volume: 37ml/4℃ 100ml/4℃
2. Counter weight: It has a hole in the center that may be filled with lead particles to adjust the mass.
