The tester is for the air permeability testing cap cap and customized special detector.

According to the British BS7272 testing standard, under the pressure of 1.33 Kpa, ventilation must meet certain standards.

Working principle:

0.1 a 0.2 Mpa gas into the flow tester, cap after decompression, under the pressure of 0.1 Mpa. After decompression, about 40 kpa pressure control in.

Access to the meter for the ventilation test cap.

Method of use:

On 220 v power supply, press the power button among, the electricity.

Insert on the outlet is the lid of the test.

0.2 Mpa pressure gas after 8 mm Ф cannula into the tester.

Rotational flow control knob. When positive digital display shows 1.33 Kpa pressure ventilation can read the cumulative flow on flow display, accumulative total to reset, in according to the cumulative state, hold the upper instrument reset button, press the switch button again. Press the switch button "*" symbol Ann in which is the instantaneous flow rate of per minute (in liters).
