（China）YYP 506 Particulate Filtration Efficiency Tester

III.Instrument characteristics:

1. Adopt high-precision imported brand differential pressure transmitter to ensure the accuracy and stability of the air resistance differential pressure of the tested sample.

2.The use of well-known brands of high-precision counter sensor, monitoring particle concentration, to ensure accurate, stable, fast and effective sampling.

3. The test inlet and outlet air is equipped with a cleaning device to ensure that the test air is clean and the exclusion air is clean, and the test environment is pollution-free.

4. The use of frequency control mainstream fan speed automatic control test flow and stable within the set flow rate of ±0.5L/min.

5. Collision multi-nozzle design is adopted to ensure rapid and stable adjustment of fog concentration. Dust particle size meets the following requirements

6. With 10-inch touch screen, Omron PLC controller. Test results are displayed or printed directly. Test results include test reports and loading reports.

7. The whole machine operation is simple, just place the sample between the fixture, and press the two start keys of the anti-pinch hand device at the same time. There is no need to do a blank test.

8. The machine noise is less than 65dB.

9. Built-in automatic calibration particle concentration program, just input the actual test load weight into the instrument, the instrument automatically completes automatic calibration according to the set load.

10. The instrument built-in sensor automatic purification function, the instrument automatically enters the sensor automatic cleaning after the test, to ensure the zero consistency of the sensor.
