A tyre pressure gauge is dual calibrated 50–300lbf/in2 and 4 to 20 bar. The gauge allows quick and accurate pressure checks. The twin head can accommodate both the 0·302in. (7·75mm) valves used on most commercial aircraft, and the larger 0·482in. (12·24mm) valves used on Boeing 747's and some military aircraft, even where the 0·482in. valve is fitted with a standard core. A patented valve arrangement automatically isolates the inoperative head. The solid alloy indicator has easy‐to‐read figures, and a self‐adjusting friction device allows pressure readings to be taken when the gauge is removed from the tyre valve. The gauge is accurate to ±0·2 bar (±2·91bf/in.2), even at the top of the range. The wide‐band calibration gauge is fitted with a black vulcanite handle, ruggedly built to withstand hard usage, and shockproof. The shape of the gauge ensures that it will not roll off inclined surfaces. The gauge is packed in a strong wooden box.
