Đồng hồ áp suất

Đồng hồ áp suất : 

APPLICATIONS
 Measure all liquid and gas process media
compatible with stainless steel.
The  glycerin  /  silicon  oil  filled  type  is
especially  used  for  measuring  points  in
vibrational  and  highly  dynamic  pressure
load. Particularly used in chemical,
petrochemical, food industry, biochemistry
and any rush industries.
