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. .
