AT902 Automated Filter Tester
AT902 AUTOMATED FILTER TESTER

Application:
AT902 Automated Filter Tester is a universal tester, development according to the standard of GB2626-2006-6.3, EN 149:2009, it mainly used for detecting the efficiency of the particulate respirator filtration and detecting the filtration efficiency and resistance of material.
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.
By detecting the concentration of upstream and downstream, and then calculate the results through the formula. Airflow can be real-time monitored through electric proportional valve and flow meter, to ensure the accuracy of the test flow and the stability. The aerosol concentration can be monitored by electrical proportional valve and differential gauge, and provide stable test particles.
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, and the efficiency.
2) Measuring the particle number and the resistance of sample in a test period.
3) The data stored in D: D: Eff(NaCl)-data, Or.D: Eff(Oil)-data
4) Showing operating parameters.
5) The system makes use of serial communication to initiating a transfer of the data files.
