4 Pcs HVAC Digital Manifold Vacuum Gauge Refrigerant Charging, Vacuum Testing and Leak Detection with 1/4"-5/16" Port Valve Core Remover Installer Tool 1/4" SAE Connector and T-Connector

Features: To turn on, press any button. To turn off, press and hold the two buttons at the bottom for 2 seconds. The instrument will automatically shut off after 15 minutes of inactivity to ensure battery life. Note: the automatic shut-off function is not active in pressure leak test mode. The package also includes a 1/4" T-shaped brass tee connector and an extension connector, used for splitting, combining, or changing the direction of fluid flow, connecting the pressure gauge to the instrument under test, ensuring safe and flexible installation in various maintenance environments. Specifications: Material: brass, metal, plastic Color: pressure gauge: green Size: 6.7"x 3.5"x 1.9" Package includes: 1 x Digital pressure gauge 1 x Brass tee adapter 1 x Brass dual head adapter 1 x Valve core removal tool Notes: Manual measurement, please allow slight errors on size. The color may exist a slight difference due to different screen displays. Do not use or store the instrument in high-temperature, high-humidity, flammable, explosive, or strong electromagnetic environments

• Convenient Kit: the package includes a digital manifold pressure gauge, a dual-size vacuum valve core removal tool, a 1/4" brass tee connector, and a 1/4" bent extension adapter; Suitable for air conditioning equipment maintenance and residential/commercial refrigeration systems; Ideal for HVAC and refrigeration technicians
• Multifunctional Pressure Gauge: the A/C digital pressure gauge is an auxiliary tool for the installation, testing, and maintenance of refrigeration equipment such as air conditioners and cold storage units; It comes pre-loaded with specifications for 24 common refrigerants (R22, R410A, R32, etc.), integrating refrigerant charging, vacuum testing, and leak detection functions to simplify the entire air conditioning and heating system maintenance process
• Data Acquisition: the refrigerants digital AC gauges supports digital readings, and high-precision dual-stage pressure valves and sensor technology ensure a pressure measurement accuracy of ±0.5%; The display screen features a backlight for clear readings in dim environments; Built-in vacuum test units (kPa, MPa, bar, inHg, PSI, Kgf/cm²) and Celsius/Fahrenheit temperature units allow for multi-unit switching
• Appearance Design: the display screen features a backlight function for clear readings in dim environments, and a rear-mounted hook for convenient use; The sight glass design allows observation of the refrigerant charging status; The instrument has a 1/4" SAE standard interface for refrigerant injection at the bottom; Requires two AA 1.5V batteries (not included); Please refer to the instruction manual for more functions and precautions
• Valve Core Removal: the valve core removal tool is made of brass, sturdy and durable, and can be served with a vacuum gauge; Suitable for refrigerant charging, vacuuming, and valve core replacement; The tight structure prevents refrigerant leakage; Dual-size SAE 1/4'' and 5/16'' interfaces make it suitable for R22, R12, R407, R410, R404, R32, and other air conditioning systems
