F4AD Digital Pressure Gauge Low Voltage AC DC Powered. NEMA 4X
F4ADBL Digital Pressure Gauge Low Voltage AC DC Powered with Backlit Display. NEMA 4X
The F4AD and F4ADBL are designed for applications where a continuous use display of pressure (or vacuum) is required.
The Falcon Digi ProTM series is a versatile family of industrial pressure/vacuum gauges featuring a rugged NEMA 4X case.
This type of enclosure, when properly installed, is suitable for indoor or outdoor non-hazardous locations and provides a degree of protection against falling dirt, rain, sleet, snow,
windblown dust, splashing water, hose-directed water, corrosion and ice formation.
Many different standard pressure/vacuum ranges (in a choice of engineering units) in both gauge and absolute references are available.
