Before You Order And Use

Confirm the currently supported units, battery requirement, and intended pressure test scenario before using PT520 in a workshop workflow.

PA Display Not Supported

The current PT520 version no longer supports PA unit display. Do not order PT520 if your workflow specifically requires direct PA display.

Use Supported Units

PT520 supports kPa, hPa, Torr, mbar, inHg, mmHg, inH2O, mmH2O, psi, and kg/cm². Use one of these units during measurement.

Battery Powered

The meter uses 4 × 1.5V AAA batteries. Check battery level on the screen before long tests or field work.

Application Confirmation

PT520 is suitable for differential pressure, positive pressure, and negative pressure checks within its rated range. Confirm compatibility before special HVAC, gas, or non-automotive use.

Non-Corrosive Media

Use the tool only with suitable non-corrosive oil, water, air, and natural gas pressure checks under proper conditions.

Adapters Follow Package

Multiple adapters are shown in the product images. Final accessories should follow the packing list image and actual package contents.

Key Features

PT520 combines high-accuracy pressure sensing, dual-port differential pressure measurement, data locking, storage, unit switching, a backlit display, and practical workshop details in a compact handheld meter.

High-Precision Pressure Sensor

The broad -100~200kPa range and ±0.3%FS accuracy help provide responsive readings for automotive and workshop pressure checks.

Positive, Negative And Differential Pressure

Dual pressure input ports allow positive pressure, negative pressure, and differential pressure measurement for more flexible diagnostics.

Data Locking And 29-Set Storage

Lock current readings during testing, zero data when needed, and review up to 29 stored records for later reference.

10 Switchable Units

Switch among kPa, hPa, Torr, mbar, inHg, mmHg, inH2O, mmH2O, psi, and kg/cm². PA unit display is not supported in the current version.

Readable Backlit Display

The HD backlit screen shows battery level, data records, Max/Min values, differential pressure, real-time positive and negative pressure, working time, and unit display.

Workshop-Friendly Details

Anti-slip silicone, side lanyard, illumination light, Type-C interface, data lock button, calibration button, and multiple measurement adapters support convenient field operation.

Applications

PT520 helps technicians check common automotive positive, negative, and differential pressure conditions within the rated measurement range.

Intake Manifold Vacuum

Check intake manifold vacuum and pressure behavior during automotive diagnostics.

Brake Booster Pressure

Use PT520 for brake booster pressure checks when the required pressure range and adapters are suitable.

Crankcase Negative Pressure

Measure crankcase negative pressure for maintenance and diagnostic reference.

Exhaust Valve Negative Pressure

Support exhaust valve negative pressure testing and related workshop pressure checks.

Application Notes

Suitable for pressure checks involving non-corrosive oil, water, air, and natural gas under proper conditions.
Do not exceed the PT520 rated pressure range.
Confirm adapter fit before connecting to pipelines with special diameters or fittings.
