VALUE Vacuum Pressure Gauge
60mm Dial Stainless Steel Case Brass Connector | Class 1.6 Accuracy | Multi-Unit Scale for HVAC Vacuum Pump Refrigeration Repair
1. Professional-Grade Accuracy, Clear & Intuitive Reading
• Equipped with a precision movement that reaches Class 1.6 accuracy standard, with an error of only ±1.6% FS, ensuring reliable measurement data and supporting professional system diagnosis.
• 3-in-1 composite dial with mbar, MPa, psi three units marked at the same time, no manual unit conversion required; the scale is clearly layered, and the numerical value can be read quickly even in dim workshop environments.
• Built-in anti-vibration structure, the pointer remains stable without jitter during vacuum pump operation, supporting continuous real-time vacuum monitoring.
2. Heavy-Duty Material for Extended Service Life
• Stainless Steel Gauge Case: Rust-proof, corrosion-resistant and impact-resistant, far more durable than ordinary plastic-case vacuum gauges, adapts to humid machine rooms, outdoor construction sites and other harsh working conditions.
• All-Brass Thread Connector: High sealing performance, no air leakage under negative pressure working condition; strong oxidation resistance, maintains good tightness after long-term frequent installation and disassembly.
• High-Transparency PC Lens: Scratch-resistant and impact-resistant, high light transmittance, keeps clear vision after long-term use without yellowing.
3. Multi-Interface Compatibility, Easy & Quick Installation
• Standard bottom-mounted 1/8" NPT male thread, perfectly fits original VALUE vacuum pumps and most conventional vacuum equipment on the market.
• Optional brass multi-function adapter supports 1/4" SAE male, 1/4" NPT male, 1/8" NPT female multiple thread specifications, no need to purchase additional adapters, easy to install with reliable sealing.
• 60mm compact dial size, does not take up extra space, can be directly installed on vacuum pumps, manifold gauges, pipelines and test benches.
4. Rugged Design for On-Site Maintenance
• Sealed structure with certain dust and moisture resistance, adapts to various complex on-site repair environments.
• Shock-absorbing internal design, effectively reduces pointer deviation and movement damage caused by vibration during transportation and equipment operation.
🎯 Wide Application Scenarios
• Household/commercial air conditioner, heat pump and cold storage vacuum pumping, pressure holding and leak detection
• Matching installation with rotary vane vacuum pumps for real-time vacuum degree monitoring
• Vacuum packaging machines, small vacuum units and industrial negative pressure pipeline testing
• Laboratory vacuum equipment and scientific research instrument vacuum measurement
• Automotive air conditioning repair and commercial refrigeration cabinet maintenance
💡 Warm Notes
1. Please confirm the thread specification of your equipment before purchasing to ensure proper matching.
2. Tighten the connector properly during installation to avoid air leakage that affects measurement accuracy; do not over-tighten to prevent thread damage.
3. This is a precision measuring instrument. Please avoid heavy impact and falling.
4. Please wipe the dial with a soft cloth. Do not rinse directly with water to prevent liquid from entering the housing and damaging the movement.
5. If the pointer fails to return to zero after long-term use, please contact us for professional calibration guidance.
