Mask Particle Protection Effect Tester , Respirator Particles Testing Machine

Mask particle protection effect tester

Overview

It is used to test the protective effect of daily protective masks and other types of masks on particulate matter. Applicable to medical device inspection centers, safety protection inspection centers, labor protection inspection centers, drug inspection centers, disease prevention and control centers, textile testing centers, hospitals, masks and respirator manufacturers.

Applicable standards

GB / T32610-2016 daily protective mask technical specifications

Technical parameter

· Adopt cold generation aerosol generator to produce continuous and stable aerosol particles, which is convenient for filling solution.

· Adopt high-precision PM2.5 sensor to measure aerosol concentration.

· The whole particle anti-leakage design protects the safety of laboratory personnel.

· 2 sets of aerosol generators: saline particulate aerosol generator and oily particulate aerosol generator.

· Equipped with aerosol particulate static neutralization device.

· Configuration temperature and humidity sensor, real-time display of ambient temperature and humidity (temperature and humidity requirements: 25 ℃±5 ℃, 30% RH±10% RH).

· Configure laser dust particle counter.

· The door opening design in front of the protective effect test chamber has good sealing performance and is equipped with operating gloves to facilitate the replacement of the mask to be inspected.

· The protective effect test uses a standard head mold: a standard head mold, imitating the real situation of people wearing protective masks.

· Protective effect aerosol particles: test chamber concentration range (20-30) mg / m3, adjustable settings, concentration fluctuation less than±10%; aerosol generator produces particle size distribution of 0. 02-2um, mass median diameter: Salt particulate matter 0.6um, oil particulate matter 0.3um.

· Protection effect aerosol concentration detection device: gas sampling flow rate (1-2) L / min, sampling frequency: 20 times / min (1-9999 times / min can be set arbitrarily), dynamic detection (0.001 001-100) mg / m3, accuracy 1%.

· Protective effect The inhaled gas sampling tube is located just below the nostril (in the mouth).

·Protection effect adopts breathing simulator to simulate human breathing state. Respiratory simulator: sinusoidal airflow, frequency 20 times / min, respiratory flow control (30±1) L / min, respirator flow range: 0-40 L / min.

· Instrument accuracy level (accuracy level): Level 1

· Control system: The computer controls the test process, automatically collects data, and configures a dedicated computer and test software.

· Automatic computer test and display: medium concentration in the warehouse, inhaled gas medium concentration, background concentration; automatic calculation: protective effect; can save, output, query, print test data.

· Power supply: AC220V 50Hz
