Series 2000 Magnehelic Differential Pressure Gages
The Series 2000 Magnehelic Differential Pressure Gages are versatile, mechanical instruments designed for precise low-pressure measurement in air and noncorrosive gas systems. With 81 models and 27 options, they indicate positive, negative (vacuum), or differential pressure without requiring power—making them ideal for isolation/hospital environments, temporary setups, and applications where electrical connectivity is limited.
Product Features
- Mechanical Operation: No power required for operation, suitable for off-grid or temporary installations. Direct mechanical indication of pressure via frictionless Magnehelic® movement.
- Accuracy & Range: Standard accuracy: ±2% FS; -HA option achieves ±1% FS for critical measurements. Wide pressure range options (e.g., 0-0.1" w.c. to 0-250" w.c.) across 81 models.
- Environmental Resistance: IP67 weatherproof rating; resists dust, water, shock, and vibration. Over-pressure tolerance: Suitable for pressures <35 psi (with Buna-N diaphragm for hydrogen applications).
- Calibration & Certification: -HA models include mirrored scale overlay to reduce parallax error. NIST calibration and 6-point certification available via Product Configurator.
- Versatile Applications: Hospital isolation wards, clean rooms, and temporary medical units. HVAC duct pressure monitoring, filter status indication, and building pressurization.
- Cost-Effective Design: Low-cost alternative to electronic gauges without compromising reliability. Simple installation and maintenance-free operation.
