Here you can find the answer to some frequently asked questions.

Question n°1

Pressure Regulator

Why does the pressure regulator stop?

Causes can be many, but the most common cause is because the regulating valve is opened too fast and/or brusquely.


This operation causes the deterioration of the protection membranes inside the regulator.


For correct use of the regulator, make sure that before being screwed onto the cylinder, the knob is turned fully counterclockwise (closed).


After connecting the cylinder, slowly turn the knob clockwise to allow the gas to pass.

Question n°2

N2H2 Cylinder

How many services can I do with one 1 L Nitrogen/Hydrogen cylinder? And how many with one 2.2 L cylinder?

It depends on the pressure used, and on the size of the system and the bottle.


With an average pressure of 8/10 bars, you can do up to 3 services with the 1 L cylinder and up to 6 services with the 2.2 L cylinder.


Question n°3

Leak Detector

Why doesn’t my leak detector find the leaks? Is it broken?

Following, you can find some simple operations that you might use to determine the cause.


The sensor has a limited functioning and it runs out with the use. Replace it to restore the correct functioning of the detector.



With the usage of the detector, its protection might get dirty or plugged up, hindering the detection.

By only replacing the protection, the leak detector should work properly again.



  • Once the leak detector is turned on, it checks and registers the concentration of gas present at that moment in the air.


  • Later on, it will signal only the concentrations that result higher than the first one.

  • Hence, do not directly point the detector on the leak when turning it on, but rather wait 45/60 seconds and then proceed.


  • After the first detection, remove the leak detector from the area of interest and wait a few seconds before proceeding with a second, more accurate, detection.


  • Please, remember that it is important not to use the detector in a gas saturated environment.
