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

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

Confirm the currently supported units, battery requirement, and intended pressure test scenario before using PT520 in a workshop workflow.<\/p>\n <\/div>\n

\n
\n

PA Display Not Supported<\/h3>\n

The current PT520 version no longer supports PA unit display. Do not order PT520 if your workflow specifically requires direct PA display.<\/p>\n <\/article>\n

\n

Use Supported Units<\/h3>\n

PT520 supports kPa, hPa, Torr, mbar, inHg, mmHg, inH2O, mmH2O, psi, and kg\/cm\u00b2. Use one of these units during measurement.<\/p>\n <\/article>\n

\n

Battery Powered<\/h3>\n

The meter uses 4 \u00d7 1.5V AAA batteries. Check battery level on the screen before long tests or field work.<\/p>\n <\/article>\n

\n

Application Confirmation<\/h3>\n

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.<\/p>\n <\/article>\n

\n

Non-Corrosive Media<\/h3>\n

Use the tool only with suitable non-corrosive oil, water, air, and natural gas pressure checks under proper conditions.<\/p>\n <\/article>\n

\n

Adapters Follow Package<\/h3>\n

Multiple adapters are shown in the product images. Final accessories should follow the packing list image and actual package contents.<\/p>\n <\/article>\n <\/div>\n <\/section>\n\n

\n
Key Features<\/div>\n

Key Features<\/h2>\n

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

\n
\n

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

The broad -100~200kPa range and \u00b10.3%FS accuracy help provide responsive readings for automotive and workshop pressure checks.<\/p>\n <\/article>\n

\n

Positive, Negative And Differential Pressure<\/h3>\n

Dual pressure input ports allow positive pressure, negative pressure, and differential pressure measurement for more flexible diagnostics.<\/p>\n <\/article>\n

\n

Data Locking And 29-Set Storage<\/h3>\n

Lock current readings during testing, zero data when needed, and review up to 29 stored records for later reference.<\/p>\n <\/article>\n

\n

10 Switchable Units<\/h3>\n

Switch among kPa, hPa, Torr, mbar, inHg, mmHg, inH2O, mmH2O, psi, and kg\/cm\u00b2. PA unit display is not supported in the current version.<\/p>\n <\/article>\n

\n

Readable Backlit Display<\/h3>\n

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.<\/p>\n <\/article>\n

\n

Workshop-Friendly Details<\/h3>\n

Anti-slip silicone, side lanyard, illumination light, Type-C interface, data lock button, calibration button, and multiple measurement adapters support convenient field operation.<\/p>\n <\/article>\n <\/div>\n\n
