Detailed Product Description
|
Particle filtration efficiency tester(PFE) Scope of application: Especially used for calibration: infrared forehead temperature gun,
infrared ear thermometer, portable infrared thermometer medical
thermometer, infrared body surface screening instrument; Standards: GB / T 32610-2016 ,GB / T19083-2010 ,YY/T 2626-2019 ,YY0469-2011 Constituent part : Aerosol generator - It is mainly used for the test of high concentration aerosol,PSL
standard particles of 0.3um are used, and the particle size range
of the main particles emitted is ≥0.3um, accounting for more than
70% of the total, which can continuously and stably produce
aerosols. Upstream of the filter material, the test particles are
provided. Particle counter - It is mainly used to monitor the concentration of upstream and
downstream particles of the measured filter material and obtain the
efficiency of the measured filter material. Differential pressure transducer - It is mainly used to test the pressure difference (or resistance)
of the measured filter material under a certain test flow rate. Stainless Steel Clamps - Mainly used for the pressure and sealing of the measured filter
material. Air pump -Mainly used for the test flow through the filter material, stable
flow, green energy saving, small vibration noise. Electrical control and software Circuit control and operation of equipment, calculation and data
processing of software, stability judgment of upstream
concentration, operation control, parameter setting. Technical Parameters:
- Test mode: initial efficiency and loading efficiency - Test temperature: (25 ± 5) ℃ - Relative humidity: (30 ± 10)% - External dimensions: 950 × 600 × 600mm - Gas source: flow 198L / min (0.6Mpa) at 550kPa - Power source: AC220V 50Hz - Weight: 100kg |
