The low side gauge has a pressure scale of 30 inHg VAC to 250 psig and the high side gauge has a pressure scale of 0 to 800 psig. Gauges come with a backlight to enhance the view and make the gauges easy to see in low light conditions.Automatic shutdown after 15 minutes of inactivity. Low battery indicator. Hoses NOT included.
