Digital Refrigerant Manifold Gauge Set with 93 Refrigerant Databases, HVAC Pressure Gauge for Vacuum & Leak Testing, Backlit LCD, HVAC Diagnostic Tool

The VIVANTECH Digital Refrigerant Manifold Gauge is a professional-grade diagnostic instrument designed for HVAC / AUTO technicians, refrigeration service professionals, and maintenance engineers. Whether you're working on residential air conditioners, commercial cold storage units, or automotive AC systems, this manifold gauge set delivers accurate and reliable performance in a rugged, user-friendly package. Key Features & Benefits: Multi-Function Testing: Supports pressure gauge mode, vacuum testing, and leak detection with real-time pressure differential tracking. Refrigerant Database Integration: Instantly access saturation temperatures for 93 refrigerants (NIST-based), making it easier to evaluate subcooling and superheat conditions. Wide Pressure Range: Measures from -101 kPa to 6000 kPa (gauge pressure), with an overload limit of 10,000 kPa for added safety during high-pressure tests. Heavy-Duty Hose Compatibility: Standard 1/4" SAE inlets and outlets with durable hose construction. Max operating pressure of 600 PSI (hose rating up to 3000 PSI burst pressure). User-Friendly Controls: Navigate functions and settings with ease using the ARROW and SETTING buttons. Long-press to save refrigerant type, pressure unit, and temperature unit preferences. Safety First: Designed in compliance with safety standards. Includes low battery indicator and overpressure protection. Applications: Refrigerant charging and recovery System evacuation verification Pressure leak testing after service Evaporator and condenser temperature monitoring Field troubleshooting of AC and refrigeration systems Package Includes: 1 x Digital Manifold Gauge 1 x User Manual 1 x Portable Case 1 x Battery Set Note: Always verify pressure ratings of the equipment under test and use appropriate personal protective equipment (PPE) when handling refrigerants.

• ALL-IN-ONE HVAC DIAGNOSTIC TOOL – This digital refrigeration manifold gauge designed for installation, maintenance, and troubleshooting of air conditioning and refrigeration systems. It supports pressure testing, vacuum testing, and pressure leak testing with precise digital readouts and multi-unit switching (Kpa, Mpa, bar, inHg, PSI)
• BUILT-IN 93 REFRIGERANT DATABASE – Based on the NIST standard, this HVAC gauge includes an extensive refrigerant library for intelligent saturation temperature calculation (condensation and evaporation). Quickly access refrigerant properties without manual reference charts.
• HIGH PRECISION & DURABLE DESIGN – Equipped with a 32-bit digital processor and high-accuracy sensor, it delivers reliable readings with ±0.5% FS accuracy. The housing is made from high-strength engineering plastic with a non-slip silicone grip for durability and comfort in the field.
• VACUUM & PRESSURE LEAK TESTING – Perform vacuum tests and pressure leak tests with time tracking. Ideal for HVAC/R technicians needing to monitor system pressure changes after refrigerant charging or evacuation.
• BACKLIT LCD DISPLAY – Easily read test results in dark or tight spaces with the large backlit screen. The intuitive interface and heavy-duty valve system with 1/4" inlets ensure long-lasting performance and compatibility with standard HVAC hoses.
