30 Lb Glow-In Dark Air Gauge

The TANNER 30 Lb Glow-In-Dark Air Gauge (Model 20330) is an analog tire pressure gauge designed for drivers who need reliable tire pressure readings in low-light conditions. With a 0–30 PSI measurement range and luminescent face, this gauge delivers accuracy when visibility is limited—whether you're performing vehicle maintenance in dim garages, checking tire pressures before dawn trailhead departures, or troubleshooting sidewall pressure issues at night.

Specifications emphasize straightforward functionality: the 2.5-inch diameter dial face is easy to read, and the gauge increments in 0.5 lb steps, providing the precision needed for standard tire pressure checks without requiring electronics or batteries. The glow-in-the-dark feature charges passively under ambient light and illuminates the gauge face and needle markings, making pressure confirmation possible without a flashlight. Its durable construction ensures it can withstand repeated field use.

This gauge is ideal for drivers, fleet maintenance technicians, off-road enthusiasts, and anyone who performs regular tire pressure monitoring outside ideal lighting. The 0–30 PSI range covers standard passenger car and light truck tire pressures (typically 28–35 PSI), making it unsuitable for high-pressure applications like air suspension or commercial truck applications, but perfect for routine automotive checks.
