Testeur d'efficacité de filtration de masque PFT-01

Le testeur d'efficacité de filtration de masque est également appelé testeur de filtrabilité de masque et testeur de performance de filtre de masque.Il est principalement adapté à la détection de l'efficacité du filtre des masques et des tissus soufflés par fusion. Cette machine de test peut générer des aérosols salés et huileux

Paramètres principaux du testeur d'efficacité de filtration de masque :

Nom commun : Détecteur d'efficacité de filtration des particules

Plage de détection d'efficacité de dépassement : 0-99,999 %

Précision : Classe 1

Plage de débitmètre de détection d'efficacité de dépassement : 10-100 L/min

Précision du débitmètre : classe 2,5

Fréquence d'échantillonnage : 1-9999 fois/min

Efficacité de filtration Concentration de particules : 20-30mg/m3

Diamètre médian de comptage : particules de sel (0,075±0,02) μm, particules d'huile (0,185±0,02) μm

Écart-type géométrique de la distribution granulométrique : particules de sel≤1,86, particules d'huile≤1,60

Plage de détection dynamique : 0,001-100 mg/m3, précision 1 %

Alimentation hôte : 220VAC 50Hz

Poids net de l'unité principale : 64 kg

Configuration de l'instrument : hôte, ordinateur, logiciel professionnel, générateur d'aérosol, compteur de particules de poussière laser, débitmètre à rotor en verre, pompe à vide

Principe du test : la détection de l'efficacité de la filtration consiste à pénétrer en continu dans l'élément filtrant avec des particules de concentration et de distribution granulométrique spécifiées sous un certain débit d'air, et à mesurer l'efficacité de la filtration de "chargement", c'est-à-dire de simuler le processus d'utilisation réel , la matière particulaire a une certaine quantité sur le matériau du filtre Efficacité dans l'état de dépôt (capacité de rétention de la poussière).

Multi-Functional Scratch tester For automotive interior materials

Multi-Functional Scratch tester is applicable to all types of wiping performance test of automotive interior materials; test equipment integrated three domestic standards (fingers scraping method, a hundred grid method, and plastic scraping finger scraping method). Scratch tester is an electronic instrument capable of measuring critical load, adhesion, scratch resistance and bond strength for a wide range of surfaces. Scratch tester measures the scratch resistance of a sliding and moving surface in the relative motion to a stylus. The stylus is forced/pressed against the moving surface with precise controlled force which is normal to the surface and tangential force at the contact has to be measured. Scratch tester can be utilized for all type of industrial coating from the plasma layers used in semiconductor and optical technology used in decorative coatings used for automotive and consumer goods. Scratch tester is used in various applications such as

FMVSS 302 With Horizontal Flammability Tester

FMVSS 302 is one of the most important to crash survivability. This standard not only designates acceptable flammability characteristics of materials to be used in vehicle interiors but also outlines specifications for testing these properties and interpreting their results. By comparing their findings against the desired burn characteristics, auto manufacturers and parts suppliers can ensure their interior materials are approved for use. Test instruments : Horizontal Flammability Tester ; Test Procedure of Horizontal Flame Tester ： a.Mount the specimen so that both sides and one end are held by the U-shaped frame, and one end is even with the open end of the frame. Where the maximum available width of a specimen is not more than 51 mm, so that the sides of the specimen cannot be held in the U-shaped frame, place the specimen in position on wire supports as described in S5.1.3, with one end held by the closed end of the U-shaped frame. b.Place the mounted specimen in a hori

Zipper Tester, Slide Fastener Reciprocating Tester

The Zipper Tester, also known as a Slide Fastener Reciprocating Tester, is a specialized device used to test the durability and functionality of zippers or slide fasteners. It is commonly used in the textile, garment, and bag manufacturing industries to ensure the quality of zippers used in various products. The tester simulates the repeated opening and closing actions that zippers undergo during normal usage. It evaluates the zipper's resistance to wear and tear, as well as its ability to withstand the repetitive movements and forces applied during regular operation. The Zipper Tester typically consists of a testing chamber or fixture, where the zipper is securely clamped. The tester applies a controlled reciprocating motion to the zipper slider, repeatedly opening and closing the zipper according to predefined parameters, such as cycle count and speed. During the testing process, the machine measures various performance parameters, including the force required to open and close t
