Product Overview
Matrix Industrial Traders Magnehelic Differential Pressure Gauges represent the gold standard in low-range differential air pressure measurement. Employing a frictionless magnetic helix drive, this gauge measures positive, negative, or differential air pressures with instantaneous response and zero hysteresis.
Key Features
- Magnetic Frictionless Movement: Eliminates gear friction, wear, and mechanical backlash for prolonged calibration stability.
- High Overpressure Protection: Internal rubber diaphragm safely absorbs overpressure shocks up to 1.7 Bar (25 PSI).
- Clear Acrylic Bezel & Scale: Distortion-free viewing with dual zero-adjustment access.
- Dual Porting: Includes side and back dual 1/8″ NPT high and low pressure ports for surface or flush panel mounting.
