Applications and Features
l Apply high accuracy MEMS sensor and digital technologies, can measure positive, negative or differential pressure
l It can measure system pressure of fan, blower, filter, furnace draft and orifice plate and can apply to various clean room, biological safety cabinet, clean bench, ducts collection, medical or pharmaceutical machine, etc.
l Multiple ranges, outputs, engineering units selectable
l Suitable for surface, panel or flush mount
l No moving parts, no vibration, ultra-thin design (only 33mm)
l State of art housing, big screen LCD display, accuracy up to ±1%FS
l Key function: zero calibration, engineering unit switching, response time setting, range / signal calibration, etc.
