A good device, made in general qualitatively. The only thing was that the needle of the low pressure gauge was not exactly at zero, I had to correct it with an adjusting screw, which can be accessed through a hole in the scale, covered with a cap. Those. the vacuum gauge is not very accurate and it has a too small scale, without atmospheric pressure compensation. Therefore, if you need to control exactly the vacuum, then it is better to purchase a more accurate device, for example, Becool BC-VG. And so, as an everyday device for servicing cryogenic equipment, it will do.
