Product Description High quality Automated Filter Tester For Mask Testing GW-902Application:AT902 Automated Filter Tester is a universal tester, development according to the standard of NIOSH 42 CFR 84, EN 149:2009, it mainly used for detecting the efficiency of the particulate respirator filtration and detecting the filtration efficiency and resistance of material. Using high precision photometer as detector to ensure accurateresults.The tester is divided into two categories, oil and salt fog. The oil spray tester is using DEHS as aerosol and the salt spray tester using NaCl, the solution spray after Ruskin nozzle and drying, then form in to aerosol. The system adopts precision instrument to control flow and concentration, and through integrate of system to communicate with computer, the system has good stability, and it is easy to operate.The filtering material tester is a fully automatic instrument which can control the following actions by a computer:1.It can feedback control and read all of the working parameters automatically: including the volume, the resistance, test time and the efficiency.2.Measuring the particle number and the resistance of sample in a test period.3.Showing operating parameters.4.The system makes use of serial communication to initiating a transfer of the data files.Standards For: EN134 \GB2626-200\JMOL\NIOSH42 CFR 84Technical Specification: DetectorphotometerAir volume(20~100) L/minEfficiency0%-99.99999% Test time≤14SLoading efficiency10%-99.999%Photometer detect aerosol concentration range0.001~100 mg/m3 AerosolSalt, DOP, DEHS, Paroline, Corn oil, optional Resistance 0-1000Pa Aerosol density(50~200) mg/m3(oil); (12~20)mg/m3(salt) Measuring range 0.3~1μm Detect temperature 5~ 35oC Related humidity0 ~ 90% RH Pressure detectDigital pressure sensor (pressure difference transmitter) Pressure detect range(0~0.88)MPaEfficiency testing range filter efficiency: 10~99.999% Operation display computerPower supply 110V/220V, 50/60HzCounting median diameter 0.075±0.02μm (salt) 0.185±0.02μm(oil) Geometric standard deviation of article size distribution <1.86(salt) <1.6(oil) Machine Construe:Features: StructureSplit-type design, customer can change the generator easily.Aluminium profile frame, nice and easy to clear.The machine can be calibrated and all the origin date is available.MultifunctionThis machine can be used for different filter materialCustomized clamp for different sample size is availableBoth salt solution and oil solution test can run on this machine SoftwareSupport Chinese and English, menu type operating mode and large LCD display, it's easy to switchTwo test method available: efficient test and load testSimple, fast and automated operationHigh AccuracyAdopted high quality photometerEquipped with oil water separator to avoid water effect test resultTest date accuracy reach to 0.00001% Standard Configuration:Main machine 1SETComputer1SETSoftware1COPYGenerator2SETSAir filter1SETPrecision filter1SETFilter element1SETRespirator frock1SETMelt adhesive device1SETCalibration filter material50PCSAir pipe joint1BOXWash bottle1PCOptional Configuration:Customized filter holders Air compressor What about the product quality?
