Overview

The ORF-RH1890 particle filtration efficiency tester can simulate the actual usage environment of Kou masks, medical Kou masks, and protective Kou masks, and perform filtration efficiency based on standard requirements for oil mist and salt mist methods. $r $n filtering efficiency: the percentage of particulate matter filtered out by the filtering element under specified detection conditions; $r $n oil mist method detection: using oil-based or equivalent substances such as DEHP/PAO/DSP as aerosols to detect or filter the filtration performance of the filter material; Salt spray detection: a method of detecting the filtration performance of filter media using NaCl or equivalent halides as aerosols;

Product Details

Particle filtration efficiency tester ORF-RH1890

Before introducing the testing instruments, first of all, popularize the following relevant knowledge:
1、 Filtration efficiency:The percentage of particulate matter filtered out by the filter element under specified testing conditions;
2、 Oil mist detection:Use oil-based or equivalent substances such as DEHP/PAO/DSP as aerosols to test the filtration performance of the hood or filter material;
Salt spray detection:The method of using NaCl or equivalent halides as aerosols to test the filtration performance of hood or filter media;

The PFT-01 particle filtration efficiency tester developed and produced by Shenzhen Ouruifan Equipment Co., Ltd. using oil mist and salt mist methods is used for testing the particle filtration efficiency of daily protective masks, medical masks, and respirators.
