MP11 Differential Pressure Gauge - Single Diaphragm | Miepl
                     MP11 DIFFERENTIAL PRESSURE GAUGE
Single 
Diaphragm
MIEPL make differential pressure gauges are made  
of highly corrosion-resistant stainless steel and  
feature an all-metal. A high overload safety is  
achieved by the all-metal construction and the close-
tting design of the pressure measuring diaphragm. .
