AUTOOL PT610 Digital Compression Tester

AUTOOL PT610 Cylinder Pressure Gauge

Professional 2.8” LCD Engine Compression Tester

The AUTOOL PT610 is a digital engine compression tester for diagnosing worn piston rings, burnt or leaking valves and failed head gaskets on petrol engines. It replaces a traditional analogue gauge with a clear digital reading, and stores the result for each cylinder so you can compare them side by side.

Screw the matching adapter into the spark plug hole, crank the engine and read the result on the 2.8-inch backlit screen. Save each cylinder, then review all results together to spot the weak one.

Main Features

Stores 6 cylinder results: save and compare compression across up to six cylinders, with data lock, clear and record functions.
Digital reading: 0–29.4 bar / 0–426.6 psi / 0–30 kg/cm² with 0.01 resolution.
Average and per-cylinder pressure: see each cylinder's result and the average across the engine.
Temperature and test time: displayed alongside pressure, in °C or °F.
Spark plug thread adapters: M10, M12, M14, M16 and M18 to suit cars, motorcycles and small engines.
2 m reinforced hose: reach the spark plug hole while reading the screen.
Quick-release valve: releases pressure between cylinders for the next test.
Riveted copper fittings: resist rust and corrosion.
Switchable units: psi, bar and kg/cm².

Important Notes

Designed for petrol engines. Many diesel engines exceed the 29.4 bar range and need a diesel compression tester.
Resolution is not the same as accuracy. Compare cylinders against each other and the manufacturer's specification.
Follow the vehicle's compression test procedure: disable fuel and ignition, and hold the throttle open while cranking.
