Product Details:
The 2000 Series Magnehelic® differential pressure gauges provide an accurate, economical indication of positive, negative, or differential air pressure in HVAC applications and building automation systems, BAS. The pressure gauge includes a 4 in (10.2 cm) easy-to-read dial and a frictionless magnetic movement in a cast aluminum housing. The differential pressure gauge is resistant to shock, vibration, and overpressure. The Magnehelic® Gauge has both back and side connections, so that it may be either surface- or flush-mounted. Ranges are available from 0 in to 0.25 in W.C. up to 10'' W.C.
Features:
- Dwyer 2300-0 Magnehelic differential pressure gauge features a die-cast aluminium case to enhance impact strength and ensure easy flush mounting.
- It is equipped with a silicone rubber diaphragm for preventing damage from overpressure and an O-ring seal for ensuring pressure-tight assembly.
- This Dwyer Magnehelic differential pressure gauge has shock-resistant mounted jewelled bearings for minimising helix friction and a precision litho-printed scale for accurate & easy monitoring.
- It is equipped with an easily accessible zero adjustment screw for ensuring hassle-free calibration.
- This differential pressure gauge is integrated with moulded rubber pointer stops for preventing pointer over-travel and a clear plastic cap for eliminating light reflection & damage from accidental drops & blows.
- It has IP67 weatherproof design that resists shock, vibration and over-pressures.
