AUTOOL PT660
Product Overview
The AUTOOL PT660 Brake Pressure Gauge is designed for brake system checking and dual-channel brake pressure comparison. With a high-precision sensor, atmospheric pressure calibration, L/R pressure input, one-click value locking, zeroing, and a 3-inch backlit digital display, PT660 helps technicians measure and compare brake system internal fluid pressure more efficiently.
PT660 is built to capture brake pressure data from two channels, compare pressure trends, and support faster brake system diagnosis with clear digital readings.
Dual-Channel Brake Pressure Detection
Detect two brake pressure channels through the L/R input slots, making it easier to compare front / rear or left / right brake pressure behavior.
Brake Pressure Balance Comparison
Supports simultaneous pressure comparison between two brake calipers, helping technicians capture pressure differences and diagnose brake system imbalance.
High-Precision Sensor
Built-in high-precision sensor provides measurement accuracy up to ±1%FS for brake system pressure checking.
Wide Measuring Range
PT660 supports 0-210Bar measurement range with 0.1 resolution, helping cover common brake system internal fluid pressure checks.
Smart 3-Inch Backlit Display
The 3-inch backlit digital display shows pressure data clearly in bright or dim workshop environments without complicated menu browsing.
One-Click Locking And Zeroing
Supports one-click locking and zeroing, atmospheric pressure calibration, and visualized data display for more efficient brake pressure measurement.

How To Use
How To Use
Follow the correct zeroing and connection procedure before measuring brake pressure. Always check the measurement range and safety conditions before testing.
Connect L/R Pressure Input
Connect the pressure input cable to the L/R slot according to the channel you need to test or compare.
Zero Before Testing
Perform atmospheric pressure zero calibration before measurement to improve test reliability.
Install Adapter
Connect the model-specific adapter to the measurement probe and confirm the connection is secure.
Select Unit And Wheel Direction
Select the required unit, such as psi, Bar, or kg/cm², and choose the wheel direction before testing.
Start Measurement
Press the Measurement button to start brake pressure measurement and monitor the pressure values on the display.
Review And Switch Units
After measurement is complete, review the results, compare pressure values, and switch units when needed.
Use Notes
Always perform zero calibration before testing.
Pay attention to the measuring range. If the range is exceeded, the result may show the maximum or minimum value.
Check the batteries, hoses, adapters, and connections before use.
Wear safety goggles and protective gloves when working around brake fluid or system fluid.
If readings appear abnormal, repeat zeroing and confirm that the adapter and pressure input cable are properly connected.
