Meiser Accu-Gage Presta-Valve Dial Gauge with Pressure Relief: 30psi

DURABLE: Unlike piston-plunger-type gauges, this gauge is designed for heavy-duty use. The device is not affected by changes in temperature, humidity, altitude or air stream contaminants. Plus, with NO BATTERIES REQUIRED, this analog tire tool is flexible to fit all your terrain, temperature, and long-ride needs.
ACCURATE READINGS: Fitted with a Presta Valve stem and Air Chuck, this tire pressure gauge provides a seamless connection seal with no air leakage, giving you precise and accurate control whether you're checking the tire pressure or bleeding excess air.
DUAL FUNCTION: Not only does this tire pressure gauge provide quick, accurate readings — it's also equipped with a deflator valve and outfitted to release extra air from your tires for precise tire pressure adjustment.
A SAFETY INVESTMENT: Maintaining proper tire pressures improves bicycle handling and reduces the risk of tire failure across terrains, extending the life of your tires. Reduce wear and tear with a heavy-duty, all-purpose tire tool that lasts and keep yourself safe while riding for years to come.
