WM221B semi-automatic penetration tester Introduction
The WM221B semi-automatic penetration tester is based on the relevant provisions of the National Standard for Petroleum Products Test Methods GB / T269-91 "Determination of Grease and Petroleum Grease Penetration" and GB / T4509-84 "Petroleum Asphalt Penetration Measurement" Designed and manufactured, the WM221B semi-automatic penetration tester also conforms to the traffic industry standard T604-93 "Asphalt Penetration Test", which is suitable for measuring the penetration test of various greases and petroleum greases. Relevant standard needles can also be configured for solid fine particles, powders, or colloids, frozen bodies and other substance tests, as well as the inspection of cheese, sugar gum, butter, butter, fermented materials and other food materials.
WM221B semi-automatic penetration tester is also suitable for ISO2137-85 "Grease and Petroleum Grease Cone Penetration Method"; ASTMD217-82, IP50-79 "Grease Cone Penetration Method" This instrument is used to determine grease and Stone oil viscosity cone penetration, petroleum asphalt penetration, petroleum wax penetration. Features
1. The penetration tester is composed of a base, a support, an up-down adjustment mechanism, and a measurement mechanism.
2. Base adjustment mechanism: The chassis is provided with fine-adjusting anchor screws, and the surface is provided with leveling round blisters. The level of the base table can be easily adjusted by adjusting the anchor screws.
3. Support and vertical adjustment mechanism (national patent): It consists of a support rod, a support arm, and an upper and lower thickness adjustment knob. During the test, the height of the scale in the measuring mechanism can be adjusted, which has the characteristics of accurate adjustment and self-locking at any time.
4. Measuring mechanism: It consists of digital ruler, electric cone locking, manual button and timer. It has the characteristics of accurate measurement, convenient observation and operation, and no resistance when the cone slides down. Technical Parameters
