CX-NS001 Geomembrane Air Pressure Tester
Geo membrane Air pressure tester is one of CX-NS series attached
with geo membrane welding machines ,which used for testing welding
quality.
Its working principle is when welding geo membrane central cavity
filled with air under pressure
to maintain a certain period after the gauge pointer remains
unchanged weld quality is reliable.
The product is simple to operate, easy to carry, reliable
detection, especially for
detection of the construction site of the geo membrane seam
quality.

1.Parameter
0~0.6Mpa
2.Operation
(1) he test pin is stainless steel hollow needle, it will break
when improper use .
So when the needle is inserted into the membrane testing in same
direction
but not left and right direction so as not to break the needle .
(2) When the temperature is below 15 ℃, the membrane turn hard not
being easily inserted .
In this case, the membrane can be heated manually by handle heater.
(3) Testing needle insertion depth depends on weld length and
time-dependent leak .
At longer time , you can slowly push the needle forwardly to ensure
tightness between
the needle and the membrane to prevent leakage of needle , to
ensure the successful completion of testing.
(4) The test pin is properly connected with the air pump operation
. Note the pump connector needs into the soft tube,
which pressing on the black locker , and connecting the needle
valve inside the folder to the inflatable mouth ( similar as bike
inflatable ) .
(5) The test needle can be determined. Method is to use your
fingers to suppress the pinhole .
While testing needle being filled with certain air , it is normal
if reading of pressure gauge keep same after a few minutes of
reading the same normal.
(6) Being filled with certain air , if the pressure gauge reading
remains unchangeable for some time , then weld quality standards.

3.Precautions
(1)Test pin should be properly and cleanly kept .
Shall handled carefully to avoid damage.
(2)Generally the pressure of needle is appropriate at 3/ 4 of
cap,
not necessary full . The instrument should be checked regularly to
ensure the accuracy..
4.Packing List
(1) pressure testing needle 1 set
(2) Manual 1copy
