According to the environmental requirements for the placement of standard parts: Please place the standard parts in a place that is not affected by vibration, heat, fan or air conditioner blowing.becauseThe temperature of the ground changes greatly, so avoid placing the standard near the ground.Please try to make the temperature of the standard part the same as the temperature of the object being measured..To prevent direct heat transfer from the stand, it is recommended to cover it with rubber insulation material.

A brief analysis of Hirays TechnologySeal detectorWhen using differential pressure for tightness testing, there are the following requirements for standard parts: 

1, The standard product should be as consistent as possible with the material, size, shape, and internal surface area of ​​the product being tested.;And standard parts must be strictly inspectedTested and known leak-free products;

2. If the tested part allows a certain amount of leakage and the detection time is long, the standard part can be omitted and the interface end of the standard part can be plugged.Just plug your head(Make sure there is no leakage here)。

3. If the volume of the product to be measured is small, the internal volume of a pipe of appropriate length can be used instead of the standard product, and the end of the pipe can be plugged.
