High quality Automated Filter Tester For Mask Testing GW-902
Application:
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 accurate
results.
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.
