The EMPEO differential pressure gauge is designed to measure two pressures and determine their difference. The device has two separate pressure connections, marked + and −. The D and DN models allow you to monitor both pressures and their difference, while the DI 160 and DNI 160 directly indicate the differential pressure with a single arrow. In the DN and DNI versions, the measuring system is made of stainless steel.
