LFM3 Series differential pressure gauge use imported high precision sensor and digitalization technology.
They are easy installation, LCD display, clear and accurate reading, and can be applied to measure fan and blower pressures, filter resistance, air velocity, furnace draft, pressure drop across orifice plates and medical care equipment.
This series has three optional discrete output versions (relay, NPN and PNP), can be flexibly applied to control the external equipments.
