OTC Digital Compression Gauge Heads

OTC digital compression gauge heads upgrade your OTC analog compression testers with easier, faster compression digital readings. They provide advanced features, including measure, record, and playback of compression readings on up to 12 cylinders, for quicker testing and diagnosis.

OTC gauge heads can directly replace any 2 1/2 in. analog gauge with a 1/4 in. NPT male thread. The digital gauges provide easy-to-read exact, numeric measurements and can display pressures in PSI, kPA, bar, and kg/c. They feature a convenient push-button side release valve that relieves pressure for repeat testing.
