Manometer for Fire Extinguisher Pressure Gauge Bourdon Tube Pressure Gauge

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Pressure Monitoring: Utilizes a precision Bourdon tube mechanism to accurately measure and display fire extinguisher pressure levels, ensuring reliable performance across foam, water, CO₂, and dry powder extinguishers.
  • Visibility & Accessibility: Features a transparent dome for real-time pressure gauge observation without disassembly, while threaded cylindrical components enable quick installation and compatibility with standard extinguisher valve systems.

Key features

  • 1. Corrosion-Resistant Brass Material Technology

  • With a corrosion-resistant brass Bourdon tube, ensure long-lasting durability in harsh environments such as industrial or marine settings. This material outperforms traditional aluminum-based gauges, reducing the risk of rust or degradation over time.*

  • 2. Clear Visual Monitoring Design

  • With a transparent dome cover, monitor pressure levels instantly without disassembly. Unlike opaque models, this design allows real-time inspection for quick maintenance and compliance checks.*

  • 3. High-Accuracy Performance Parameters

  • Accurate within ±2% of full scale, ensuring reliable readings compared to ±5% in standard pressure gauges. This precision guarantees optimal fire extinguisher functionality across CO₂, foam, and water-based agents.*

  • 4. Multi-Agent Scenario Adaptability

  • Suitable for CO₂, dry powder, foam, and water extinguishers, this gauge adapts to diverse fire suppression needs. Its universal compatibility reduces the need for multiple specialized gauges in mixed-fire environments.*

  • 5. Certified Safety Compliance

  • Complies with NFPA (National Fire Protection Association) and UL (Underwriters Laboratories) standards, ensuring safety and regulatory adherence. This certification provides peace of mind for commercial and industrial use cases.*

Supplier's note

  1. Technical Breakthroughs:

    • Enhanced Corrosion Resistance (Pro Model): Triple the industry standard, enabling safe use in chemical plants and coastal environments.
    • Precision Accuracy (Pro Model): ±0.5% error margin ensures reliable pressure monitoring in high-risk scenarios.
    • Modular Design: Universal 3/4" NPT threading reduces downtime by 40% during component swaps.
  2. Version Selection Guide:

    • Base Model: Ideal for standard commercial settings (e.g., offices, retail) with minimal environmental exposure.
    • Advanced Model: Suitable for industrial facilities requiring anti-fog visibility and marine-grade durability.
    • Pro Model: Best for chemical processing plants or extreme environments where precision and chemical resistance are critical.

With the Pro Model’s chemical-grade stainless steel, you can safely monitor pressure in corrosive atmospheres. Pair its sapphire dome with ±0.5% accuracy to ensure compliance in high-stakes industrial applications. For routine inspections, the Advanced Model’s anti-fog window reduces downtime by 30% compared to traditional glass designs.
