Pore Size Analyzer

Introduction
 Test items:
Integrity (whether the damage of the filter, filter joint, end cap adhesive with or without defects);
The maximum bubble diameter of the first bubble point pressure filter;
The average pore size of the bubble point pressure filter;
Filtering accuracy (βx ≥ 20 corresponds to the reference value).
Test objects:
Oil filter material and air filter;
Oil filter and air filter;
All filter components of the chip filter and filter.
 Application
 Product development and quality control department monitoring center
Quality inspection and supervision institutions
Filter users and filter manufacturers
 Features
 
◆  Filter element and filter material  is easy to install;
◆ The filter element and the filter material are easy to convert to the test state (by adjusting the three-way wrench adjustment);
◆ The machine itself comes with an air pump;
◆ Temperature compensation. (Experimental results are not affected by temperature changes);
◆ Measurement data time monitoring (LCD display), the test results are intuitive and easy to understand;
◆ Come with a printer;
◆ Test results can be long-term preservation, easy to query (up to 200);
◆ The conversion coefficient between the filter precision and the average pore diameter of the six kinds of filter materials is set.
◆ With exhaust fan, protective cover;
◆ Filter automatically tightening, lifting device;
◆ A tank can be automatically added liquid, drainage;
◆ Aluminum alloy frame, stainless steel panel, stainless steel test tank.
