The gauge dial body is 3.5 inches. Each color
coded hose is 35 feet long to reach allow use on very long trailers. A
diagnostic manual is included.
|The duplex gauge is really two separate gauges in one
housing. Each color coded hose connects to an indicator needle to show air
pressure. The indicators use a common dial to allow to easy to reading and
This durable field instrument can be used to check
input and output air pressures at various points through out the air system.
This can identify air line restrictions, air system imbalances, insufficient
air supply pressures, tapped air or leaks.
Checking two separate points in an air brake system
against each other will indicate both the amounts of pressure delivered to the
test points and their relative time of arrival. This makes the Duplex Test
Gauge an invaluable air system troubleshooting device.
