Tire pressure gauge debuts

By Janice Wood · November 23, 2010 ·

Tool Testing Lab has added to its line of tools for professional mechanics and technicians with a digital, full-range (0-300 psi) full-featured tire pressure gauge.

Industry standards permit aircraft tires to lose as much as 1% of their pressure each day, and even mild underinflation can allow temperatures to rise exponentially, sometimes resulting in heat-induced failures even while taxiing, company officials note. Underinflation can cause poor tracking and landings or even total failure of the tire or the wheel. Underinflation lengthens the takeoff roll and reduces the brakes’ predictability and effectiveness.

Tool Testing Lab’s backlit digital gauge reads in PSI, InHg, Oz, SqIn, Inches or Feet, H2O, Kg, sqCm, Kpa, and Bar, with ½% tolerance and as fine as 0.1PSI resolution. It also holds peak readings, and features a built-in bleeder valve. The TTL-300-DTG-K comes in a protective fitted rubber “skin.”

The included angled and straight chucks mounted on flexible hose handles allow readings of virtually all Schraeder-valve pneumatic wheels and tubes, company officials add. Quick-disconnect couplings allow instant chuck change-out. Reads air or other inert gases such as nitrogen and is useful also in auto and truck applications.

Because tires can look different to different people or under different conditions (dusty, clean, wet), the TTL-300-DTG-K includes a tire tread depth gage. The kit is housed in a foam-fit plastic case.

This Pro Series Kit is shipped with a one-year long-form National Institute of Standards and Technology (NIST) traceable certification and a one-year warranty against defects in materials and workmanship. Priced at $295.
