AUTOOL PT680 Air Suspension Pressure Tester

AUTOOL PT680

Product Overview

The AUTOOL PT680 is a professional digital air suspension pressure tester designed to help locate pressure leaks in vehicle air suspension systems. It supports dual-channel synchronous testing for left and right air suspension circuits, calculates pressure difference in real time, and helps check air springs, pipes, and connection points in air suspension systems.

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

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.

Quick-Connect Structural Fittings

Sealed, pressure-resistant quick-connect fittings are designed for durability, convenience, and reliable connection.

3-Year Warranty Support

For eligible non-human damage cases, AUTOOL provides 3-year warranty support and accessory assistance.

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

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.
