Before You Order And Use
PT680 is built for air suspension pressure leak checks. Confirm the test object, fittings, power method, and pressure range before use.
Air Suspension Tester
PT680 is designed for air suspension system pressure leak testing, including air springs, pipes, and connection points.
Not An Engine Pressure Tester
PT680 is different from engine cylinder, engine oil, fuel, transmission oil, and brake pressure testers. Use the correct AUTOOL pressure tester for each system.
Check Adapter Fitment
Before testing, confirm that the included hoses, adapters, and fittings can connect properly to the target vehicle air suspension system.
Battery Powered
The product specifications show the operating voltage as 4 × 1.5V AAA batteries.
Type-C Interface Shown
The product detail image identifies a Type-C interface, but the supplied content does not clearly state that PT680 is rechargeable.
Use Within Rated Range
Use PT680 within its 0-20Bar measurement range and -10°C to 60°C operating temperature range.
Key Features
Key Features
PT680 combines a digital pressure sensor, dual-channel synchronous testing, pressure differential display, unit switching, a backlit screen, one-click calibration, and quick-connect fittings for efficient air suspension leak checks.
High-Precision Digital Pressure Sensor
The built-in digital pressure sensor provides ±1% FS measurement accuracy and fast response for pressure leak checking.
Dual-Channel Synchronous Test
PT680 supports simultaneous testing of left and right air suspension circuits and displays pressure changes in real time.
Pressure Difference Display
The tester calculates pressure difference to help compare left and right side pressure behavior more intuitively.
Multiple Unit Selections
Switch pressure units between psi, Bar, kg/cm², and kPa without manual conversion.
2.8-Inch Backlit Display
The 2.8-inch backlit display helps keep pressure data visible in bright daylight or dim workshop environments.
One-Click Calibration And Zeroing
Calibration and zeroing can be performed with simple button operation, helping reduce setup time during testing.
Backlit Buttons
Button illumination improves visibility during low-light workshop use and nighttime inspection work.

Product Details
PT680 does not rely on a single manual pressure reading. It monitors pressure changes and pressure difference across dual channels to help identify abnormal pressure loss.
Connect Left And Right Channels
Use the proper fittings to connect PT680 to the target left and right air suspension circuits.
Monitor Real-Time Pressure
Read LF, RF, LR, and RR pressure values, pressure units, pressure leak reminders, and test status from the display.
Compare Pressure Difference
Use the pressure difference reading and pressure holding countdown to identify which side may have abnormal pressure loss.
Applications
Applications
PT680 is suitable for many vehicles equipped with air suspension systems, especially when technicians need to compare left and right side pressure behavior.
Air Suspension Leak Checks
Helps test pressure leakage in vehicle air suspension systems during maintenance and repair.
Air Springs
Helps check pressure loss around air spring areas when the vehicle shows abnormal height or suspension behavior.
Pipes And Connections
Useful for checking pipes, adapters, and connection points in the air suspension system.
Common Vehicle Coverage
Suitable for many Audi, Volkswagen, BMW, Mercedes-Benz, Porsche, Cayenne, and Land Rover models with compatible air suspension systems.
