The tester is for the ventilation of the detection and customized detector.

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

One, working principle:

0.1 0.2Mpa gas into the pen cap flow tester, after decompression, pressure to achieve 0.1Mpa. After two times of decompression, pressure control in 40Kpa.

Enter the flow meter cap ventilation test.

Two, the use of methods:

1, plug the 220V power supply, press the power button above the middle, namely electricity.

In 2, the outlet is inserted into the pen cap on test.

In 3, 0.2Mpa pressure gas passes through the cannula into the tester with 8mm.

4, rotational flow adjusting knob. When positive pressure ventilation can display 1.33Kpa in flow display readout accumulated flow, cumulative need clear zero, in the display of the accumulated state, to press the reset button apparatus at the upper right does not move, then press the switch button. Click the toggle keys appear" *" symbol is an instantaneous flow rate ( per minute in litre ).

Three, technical parameters:

Intake air pressure: 0.21Mpa flow range: 0.75-28L / min

The first buck: 0.1Mpa second: 10-40Kpa Buck

Digital pressure: voltage: 220V 0-4Kpa

Material: stainless steel, aluminum, copper, PVC

Flow accuracy: an inlet diameter: with 8mm

Outlet pipe diameter: 10, with 12, with a diameter of 16mm
