Features:
- dual motion meters are much more sensitive. The blue low pressure gauge with a range of 0-350 psi and the red high pressure gauge with 0-500 psi. The meter has a unit of degrees fahrenheit and an easy-to-read instrument panel. Integrated precision components ensure measurement accuracy.
- they include 3 color-coded charging hoses for easy recognition, red for high pressure, blue for low pressure and yellow for refrigerant bottle.
- made of solid brass, aluminum, pvc and plastic, the pressure gauge can withstand heavy use and accidental falls, making it an ideal tool for professional automotive mechanics. It also includes a detailed diagram of the parts and step-by-step instructions to help beginners.
- through the transparent display window, you can clearly see the charging status.the professional 3-way air conditioning diagnostic pressure gauge set is designed for charging air conditioning, checking the diagnosis and performing recovery work, and it is applicable to r134a, r12, r22 and r404a refrigerants.
