## Description

## Practical tips

Made with alloy steel and brass, the AZUNO digital compression gauge comes as a kit for checking compression in gasoline engines. Its four adapters and 16-inch flexible hose with quick coupler provide connection options for the test. If you need a versatile setup for different engine connections, this kit offers a broader approach than a gauge supplied with only one adapter. The backlit screen makes readings easier to see in a garage or shop, while the side bleeder valve lets you repeat tests without disconnecting the hose.

Choose the supplied adapter that matches the engine connection, then use the digital readout to compare measured compression with the requirements for the engine being serviced. The kit is stored in a deluxe case, keeping its components together between jobs. Two AAA batteries are required.

## Benefits

The digital display presents large, clear readings and offers four units, making it practical to read and record results during engine checks. With a stated 0.1 display resolution and measurement range from 10 to 200 PSI, it’s suited to compression testing across a range of gasoline-engine applications. The auto-off feature activates after 2.5 minutes of inactivity to help preserve battery life.

The flexible hose and quick coupler make it easier to position the gauge at the test connection, while the side bleeder valve supports repeated measurements without removing the hose between tests. Four adapters add flexibility when working with different engine connections. Buyers often appreciate the straightforward operation, digital display and adapter selection. Feedback on accuracy and durability is mixed, including reports of hose or fitting separation, so careful handling of the hose assembly is relevant during use.

## Practical questions

**What is this gauge designed to test?** It is designed for compression testing on gasoline engines, with a measurement range of 10–200 PSI.

**What comes with the tester?** The kit includes four standard and specialty adapters, a 16-inch flexible hose assembly with quick coupler, and a deluxe case.

**Can you repeat a reading without disconnecting the hose?** Yes. The side bleeder valve allows repeated tests without disconnecting the hose. The gauge also has an auto-off feature after 2.5 minutes of inactivity.

## When it makes sense

It’s a good fit if you maintain or diagnose gasoline engines and want a digital compression tester with multiple adapters, a flexible hose and a clear backlit readout in one stored kit. For occasional checks in a home garage or recurring work in a shop, its range of connection options and repeat-test bleeder valve make the testing setup practical and organized.
