Before You Order And Use<\/div>\n

Before You Order And Use<\/h2>\n

PT680 is built for air suspension pressure leak checks. Confirm the test object, fittings, power method, and pressure range before use.<\/p>\n <\/div>\n

\n
\n

Air Suspension Tester<\/h3>\n

PT680 is designed for air suspension system pressure leak testing, including air springs, pipes, and connection points.<\/p>\n <\/article>\n

\n

Not An Engine Pressure Tester<\/h3>\n

PT680 is different from engine cylinder, engine oil, fuel, transmission oil, and brake pressure testers. Use the correct AUTOOL pressure tester for each system.<\/p>\n <\/article>\n

\n

Check Adapter Fitment<\/h3>\n

Before testing, confirm that the included hoses, adapters, and fittings can connect properly to the target vehicle air suspension system.<\/p>\n <\/article>\n

\n

Battery Powered<\/h3>\n

The product specifications show the operating voltage as 4 \u00d7 1.5V AAA batteries.<\/p>\n <\/article>\n

\n

Type-C Interface Shown<\/h3>\n

The product detail image identifies a Type-C interface, but the supplied content does not clearly state that PT680 is rechargeable.<\/p>\n <\/article>\n

\n

Use Within Rated Range<\/h3>\n

Use PT680 within its 0-20Bar measurement range and -10\u00b0C to 60\u00b0C operating temperature range.<\/p>\n <\/article>\n <\/div>\n <\/section>\n\n

\n
\n
Key Features<\/div>\n

Key Features<\/h2>\n

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.<\/p>\n <\/div>\n

\n
\n

High-Precision Digital Pressure Sensor<\/h3>\n

The built-in digital pressure sensor provides \u00b11% FS measurement accuracy and fast response for pressure leak checking.<\/p>\n <\/article>\n

\n

Dual-Channel Synchronous Test<\/h3>\n

PT680 supports simultaneous testing of left and right air suspension circuits and displays pressure changes in real time.<\/p>\n <\/article>\n

\n

Pressure Difference Display<\/h3>\n

The tester calculates pressure difference to help compare left and right side pressure behavior more intuitively.<\/p>\n <\/article>\n

\n

Multiple Unit Selections<\/h3>\n

Switch pressure units between psi, Bar, kg\/cm\u00b2, and kPa without manual conversion.<\/p>\n <\/article>\n

\n

2.8-Inch Backlit Display<\/h3>\n

The 2.8-inch backlit display helps keep pressure data visible in bright daylight or dim workshop environments.<\/p>\n <\/article>\n

\n

One-Click Calibration And Zeroing<\/h3>\n

Calibration and zeroing can be performed with simple button operation, helping reduce setup time during testing.<\/p>\n <\/article>\n

\n

Backlit Buttons<\/h3>\n

Button illumination improves visibility during low-light workshop use and nighttime inspection work.<\/p>\n <\/article>\n

\n

Quick-Connect Structural Fittings<\/h3>\n

Sealed, pressure-resistant quick-connect fittings are designed for durability, convenience, and reliable connection.<\/p>\n <\/article>\n

\n

3-Year Warranty Support<\/h3>\n

For eligible non-human damage cases, AUTOOL provides 3-year warranty support and accessory assistance.<\/p>\n <\/article>\n <\/div>\n\n

Product Details<\/div>\n

Product Details<\/h2>\n

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.<\/p>\n <\/div>\n

\n
\n

Connect Left And Right Channels<\/h3>\n

Use the proper fittings to connect PT680 to the target left and right air suspension circuits.<\/p>\n <\/article>\n

\n

Monitor Real-Time Pressure<\/h3>\n

Read LF, RF, LR, and RR pressure values, pressure units, pressure leak reminders, and test status from the display.<\/p>\n <\/article>\n

\n

Compare Pressure Difference<\/h3>\n

Use the pressure difference reading and pressure holding countdown to identify which side may have abnormal pressure loss.<\/p>\n <\/article>\n <\/div>\n <\/section>\n\n

\n
\n
Applications<\/div>\n

Applications<\/h2>\n

PT680 is suitable for many vehicles equipped with air suspension systems, especially when technicians need to compare left and right side pressure behavior.<\/p>\n <\/div>\n

\n
\n

Air Suspension Leak Checks<\/h3>\n

Helps test pressure leakage in vehicle air suspension systems during maintenance and repair.<\/p>\n <\/article>\n

\n

Air Springs<\/h3>\n

Helps check pressure loss around air spring areas when the vehicle shows abnormal height or suspension behavior.<\/p>\n <\/article>\n

\n

Pipes And Connections<\/h3>\n

Useful for checking pipes, adapters, and connection points in the air suspension system.<\/p>\n <\/article>\n

\n

Common Vehicle Coverage<\/h3>\n

Suitable for many Audi, Volkswagen, BMW, Mercedes-Benz, Porsche, Cayenne, and Land Rover models with compatible air suspension systems.<\/p>\n <\/article>\n <\/div>\n <\/section>\n\n
