¡ß Differential pressure gauge with diaphragm ¡ß
¡Ü Model : P661-P662
¡Ü Service intended :
P660 & 670 series differential pressure gauge are designed to measure differential pressure from 1kPa to 4MPa at static pressure of 4, 10, 25 or 40MPa. A set of two stainless steel diaphragm mounted on a force balance allows direct reading of the actual differential Pressure.
