Measuring range
As the shock-proof pressure gauge displays the pressure value by measuring the deformation of the element and driving the pointer through the magnifying mechanism to display the pressure value, you should also pay attention when selecting the range. Generally, the range of the pressure gauge 3GUB4 or 2Universe 3 is ideal. , The pointer changes small, the pressure value read is not accurate, the selection is small, the pressure gauge will be overloaded.
Connection size
Now, due to the different thread standards in various countries, the commonly used shock-proof pressure gauges mainly include M (metric), G (, British), NPT (, American), R (, Japan, South Korea, etc.).
