• Accurate digital pressure and temperature measurement for HVAC and refrigeration systems.
• Supports multiple refrigerant types with built-in refrigerant database for easy diagnostics.
• Vacuum measurement and system testing functions help ensure efficient maintenance.
• Durable, user-friendly design with clear digital display for professional field use.
The Duoyi DY517 Digital Manifold Gauge is an intelligent, multi-functional electronic diagnostic tool built for the installation, testing, and maintenance of refrigeration and HVAC equipment. It consolidates multiple traditional analog tools into a single unit, making it an excellent choice for servicing automotive air conditioning, residential HVAC, and commercial cold storage systems.
Dual-Pressure & Dual-Temperature Processing: Measures high-side and low-side pressures simultaneously along with live dual-temperature inputs.
Automatic Superheat & Subcooling Calculations: It automatically cross-references real-time pressure-temperature readouts against its internal database to provide instant superheat and subcooling data, eliminating manual calculation errors.
Comprehensive Refrigerant Database: Pre-programmed with 89 standard NIST refrigerant profiles (including R134a, R22, R410A, and R1234yf) for automatic saturation and evaporation temperature readings.
Vacuum & Leakage Testing: Features a relative vacuum tracking mode and an automated pressure-drop/leak logging test that records leak speed over a designated timeframe.
Heavy-Duty Construction: Built with high-strength engineering plastics and wrapped in a flexible, non-slip silicone bumper for industrial drop protection and a solid grip.
