Test items: Penetration test against blood-borne pathogens This instrument is specially designed for testing the permeability of medical protective clothing against blood and other liquids; the hydrostatic pressure test method is used to test the penetration ability of protective clothing materials against viruses and blood and other liquids. Used to test the permeability of protective clothing to blood and body fluids, blood pathogens (tested with Phi-X 174 antibiotic), synthetic blood, etc. It can test the anti-liquid penetration performance of protective equipment including gloves, protective clothing, outer covers, coveralls, boots, etc. 1 Product Introduction This instrument is specially designed for testing the permeability of medical protective clothing against blood and other liquids; the hydrostatic pressure test method is used to test the penetration ability of protective clothing materials against viruses and blood and other liquids. Used to test the permeability of protective clothing to blood and body fluids, blood pathogens (tested with Phi-X 174 antibiotic), synthetic blood, etc. It can test the anti-liquid penetration performance of protective equipment including gloves, protective clothing, outer covers, coveralls, boots, etc. 2 Features ● Negative pressure experiment system, equipped with fan exhaust system and high efficiency filter for inlet and outlet to ensure the safety of operators; ● Industrial-grade high-brightness color touch screen; ● U disk export historical data; ● The pressure point pressurization method adopts fully automatic adjustment to ensure the accuracy of the test. ● The special stainless steel penetrating test tank guarantees the firm clamping of the sample and prevents the synthetic blood from splashing around; ● Imported pressure sensor is adopted, with accurate data and high measurement accuracy. Volume data storage, save historical experimental data; ● Built-in high-brightness lighting lamp in the cabinet; ● Built-in leakage protection switch to protect the safety of operators; ● The inner layer of the cabinet is integrally processed into stainless steel, and the outer layer is sprayed with cold-rolled plates, and the inner and outer layers are insulated and flame-retardant. 3 matters Needing Attention In order to prevent damage to your anti-blood-borne pathogen penetration tester experimental system, please read the following carefully before using this equipment. Keep this manual so that all product users can refer to it at any time. ① The operating environment of the experimental instrument should be well ventilated, dry, free of dust, and strong electromagnetic interference. ② The instrument should be powered off for more than 10 minutes if it continues to work for 24 hours to keep the instrument in good working condition. ③ Poor contact or open circuit may occur after long-term use of the power supply. Check and repair before each use to ensure that the power cord is not damaged, cracked, or open. ④ Please use a soft cloth and neutral detergent to clean the instrument. Before cleaning, make sure to disconnect the power supply. Do not clean the instrument with thinner or benzene or other volatile substances. Otherwise, the color of the instrument casing will be damaged, the logo on the casing will be wiped off, and the touch screen display will be blurred. ⑤ Please do not disassemble this product by yourself, please contact our company's after-sales service in time if you encounter any failure. 4 Appearance Structure and Corresponding Description 1.
