AUTOOL PT503 Mini Differential Pressure Gauge

The AUTOOL PT503 is a compact mini differential pressure gauge for positive pressure, negative pressure, and differential pressure measurement. It is designed for portable on-site testing, automotive intake, brake booster, exhaust, crankcase or crankshaft-related pressure checks, and quick mobile diagnostic work. With a high-precision pressure sensor, 6 switchable pressure units, data hold, a backlit LCD display, and a reinforced portable body, PT503 helps users capture and record pressure changes clearly in workshop or field environments. PT503 combines accurate pressure sensing, a readable backlit display, one-button data hold, 6-unit switching, portable body design, and adapter support in a compact diagnostic gauge. Review the key measurement, power, display, environment, and body specifications before choosing PT503 for compact pressure testing. Use PT503 for compact automotive pressure, negative-pressure, and differential-pressure checks when the measurement range and connector setup match the test point. Install batteries, let the gauge zero in open air, connect the correct hose and adapter, select the display unit, and lock the reading when you need to record the result.
