Description
- The Duplex Test Gauge is actually two separate air pressure gauges in one housing
- Each color coded hose connects to a separate indicator needle to show the air pressure being recorded
- The indicator needles use a common dial to allow for easy reading & comparison
- This durable field instrument can be used to check input & output air pressures at various points in the air system
- This tool can identity air line restrictions, air system imbalances, insufficient air supply pressures, trapped air &
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 & their relative time of arrival
- This makes the Duplex Test Gauge an invaluable air system troubleshooting device
- A diagnostic manual is included with the Duplex Test Gauge
- The gauge dial is 3.5” in diameter
- Each color coded hose is 35’ long to reach connections on the semi-truck &/or trailer combinations
