How To Choose

Choose the right AUTOOL PT pressure tester by matching the system you need to measure: cylinder compression, engine oil, fuel, GDI fuel, transmission oil, or brake fluid pressure.

Cylinder Pressure

Choose PT610 for cylinder compression pressure testing and cylinder pressure comparison.

Engine Oil Pressure

Choose PT620 for engine oil pressure testing on motorcycles, cars, and trucks.

Fuel Pressure

Choose PT630 or PT635 for fuel pressure testing. PT635 is the higher-end version and also supports fuel temperature monitoring.

GDI Fuel Pressure

Choose PT640 for GDI high-pressure fuel testing with digital measurement up to 0-360 bar.

Transmission Oil Pressure

Choose PT650 for ATF exchanger and transmission oil pressure testing.

Brake Fluid Pressure

Choose PT660 for brake fluid pressure testing and front / rear brake pressure comparison.

Product Comparison

Use the comparison chart and model notes to quickly match the correct PT pressure tester with your required automotive pressure system.

Digital Measurement System

Features a wide measurement range and high precision, with readings accurate to two decimal places for more intuitive pressure diagnosis.

Smart Digital Display

2.8-3 inch backlit display keeps pressure data readable in bright and dim workshop environments without flipping pages.

Real-Time And Average Data

Selected models display real-time pressure, average pressure, temperature, measurement time, or related diagnostic data.

Data Saving And Locking

Selected models support data storage or data lock, making pressure test results easier to review and compare.

Copper-Riveted Construction

Copper-riveted fittings resist rust and corrosion, while reinforced rubber hoses improve pressure resistance, temperature tolerance, and kink resistance.

3-Year Warranty

For eligible damage caused by non-human factors, AUTOOL provides free replacement parts within 3 years.

Before You Order And Use

Pressure testing accuracy depends on correct zero calibration, adapter selection, and measurement range control. PT660 brake pressure testing also requires correct L/R channel connection and wheel direction selection.

General Test Notes

Perform zero calibration before every test.
Zero calibration should be done under atmospheric pressure before connecting test lines.
Pay attention to the measurement range; exceeding the range may only display maximum or minimum values.
Choose the correct adapter before connecting to the target system.
Disconnect the device and release pressure before repeating a test if the reading appears abnormal.

PT660 Brake Pressure Gauge Quick Steps

Connect the pressure input cable to the L/R slots.
Perform air pressure zero calibration before testing.
Connect the specific model adapter to the measurement probe.
Select the unit and wheel direction.
Press the measurement button to start pressure measurement.
After measurement is complete, view results and switch units if needed.
