AUTOOL PT520 Differential Pressure Gauge Digital Manometer

The AUTOOL PT520 digital manometer is a dual-port differential pressure gauge for automotive vacuum, brake booster, crankcase, exhaust valve, HVAC, gas, air, oil, and water pressure checks under proper conditions. It supports positive and negative pressure measurement, differential pressure measurement, Max/Min value recording, data locking, and up to 29 sets of stored records for workshop diagnostics and maintenance. Confirm the currently supported units, battery requirement, and intended pressure test scenario before using PT520 in a workshop workflow. 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. PT520 helps technicians check common automotive positive, negative, and differential pressure conditions within the rated measurement range. Review the PT520 power supply, pressure range, accuracy, resolution, temperature range, dimensions, and supported units before ordering. Compare the screen size, pressure range, accuracy, data storage, light functions, magnetic design, toolbox, and application range before choosing an AUTOOL digital manometer.
