MG800 PRO Digital Manifold Gauge Set - HVAC Refrigeration AC Diagnostic Tool with Temperature & Pressure Readings - Perfect for HVAC Technicians & Automotive AC Repair

• Accurate Measurements: Designed to measure the temperature and pressure of refrigeration or heat pump systems; provides precise readings from -14.5 to 800 psi and -58 to 302°F; more accurate than traditional mechanical gauges
• Enhanced Display: Features a large LCD that simultaneously shows pressure, temperature, and refrigerant data; supports Fahrenheit and Celsius; pressure units include kPa, MPa, psi, inHg, bar, and kg/cm² for broad system compatibility
• Smart Calculations: Automatically calculates superheat and subcooling values, streamlining diagnostics for faster and more effective troubleshooting; supports backlit display for easy-to-read data in low-light conditions
• Wide Compatibility: Works with 88 types of refrigerants; fully compatible with A2L refrigerants; a flame icon above the A2L refrigerant name alerts users to handle flammable refrigerants with care; includes two 1/4" SAE to 5/16" SAE adapters, suitable for both home and automotive AC systems
• Quick Refrigerant Switching: Sixteen commonly used refrigerants are arranged at the front, reducing search time and enhancing efficiency; icons for frequently used refrigerants feature a star above for faster identification and selection
• Save Power, Last Longer: Powered by three AA alkaline batteries (not included), operates for up to 200 hours with the backlight off; intelligent auto power-off function automatically detects idle status and shuts down to conserve battery power
• Convenient Storage & Portability: Comes with a sturdy case with a handle; stores a manifold gauge, two temperature clamps, three hoses, and two refrigerant adapters

Hook Design

Allows you to hang the gauge on pipes, service ports, or nearby structures, keeping hands free to connect hoses, adjust valves, or check for leaks. When not in use, the hook hides in the recessed design on the back for easy storage.

Easy Inspection

The glass sight window provides a clear view of the refrigerant flow, allowing you to monitor its condition in real time. This helps quickly identify issues like low refrigerant levels or contaminants, enhancing diagnostic efficiency.

Instant Visual Warning

A flame icon appears above the name of flammable refrigerants (A2L type) on the screen, serving as a clear warning indicator. Please handle flammable refrigerants with extra caution.

Wide Compatibility

The included 1/4" SAE to 5/16" SAE adapters ensure compatibility with different refrigeration system ports, suitable not only for home air conditioners but also for HVAC systems using R-410A refrigerant without additional specialized tools.

Warning of Using the Equipped Light:

• Ingestion Hazard: This product operates with three battery cells.
• A swallowed battery cell can cause internal chemical burns within just two hours, leading to severe injury or even death.
• Keep batteries out of reach of children, pets, and individuals with reduced physical, sensory, or mental capabilities, or those lacking experience and knowledge.
• If ingestion or insertion inside any part of the body is suspected, call poison control and seek immediate medical attention.
