Zedeyes  132 Low Differential Pressure Gauge

The Zedeyes  132 is a highly reliable low differential pressure gauge designed specifically for HVAC systems, cleanrooms, and air-filtration monitoring. Operating on a frictionless magnet-and-diaphragm system, the  132 eliminates direct mechanical linkage contact between moving parts. This frictionless movement technology prevents internal wear and tear, ensuring long-term measurement stability without accuracy degradation over time.

Constructed with a grey-coated aluminum housing, the Model 132 is tested to withstand up to 160 hours of direct salt water spray exposure without corrosion. Equipped with a high-strength nickel-plated neodymium magnet ($\text{Nd}_2\text{Fe}_{14}\text{B}$), a break-resistant acrylic window, and an integrated silicone overpressure blow-out plug, it provides a durable and economical solution for monitoring low air and non-corrosive gas differential pressure.

Key Features & Benefits

• Frictionless Magnet Movement: Magnetic coupling technology eliminates mechanical contact between moving components, preventing wear and maintaining accuracy throughout the instrument's operational life.

• Corrosion-Resistant Housing: Grey-coated aluminum enclosure endured 160 hours of continuous salt spray testing without surface degradation.

• Wide Low-Pressure Span: Measures differential pressure, positive pressure, and compound ranges from 60 Pa up to 250 inH₂O.

• Zero Adjustment Capability: Features an externally accessible front zero adjusting screw for rapid zero-point calibration in the field.

• Overpressure Safety Protection: Fitted with a silicone blow-out plug designed to pop open at approximately 26 psi to safeguard internal components against sudden pressure surges.

• Complete Installation Kit: Supplied with standard mounting accessories for immediate panel or surface installation.

Primary Applications

• Cleanrooms & Isolation Wards: Precision monitoring of cleanroom differential pressure to maintain strict environmental containment.

• HVAC & Building Automation: Duct air pressure monitoring, fan static pressure verification, and air handler balancing.

• Filter Monitoring: Tracking pressure drop across HVAC filters, dust collection systems, and air scrubbers to signal replacement cycles.

• Blower & Fan Performance: Monitoring intake/discharge static pressure across industrial ventilation units.
