Precise Digital Tire Pressure Tool with Inflation Function, 250 PSI

3 in 1 multifunctional and easy to use: This is a pressure gauge for precise monitoring of tire pressure. It is also a tire inflator for inflating tires when connected to an air compressor. In addition, it features a built-in vent valve that quickly reduces pressure in overinflated tires. High accuracy: Professionally calibrated to provide readings within 1% of actual tire pressure with a 0.1 PSI resolution. No more surprises. Measures accurately from 0 to 250 PSI (0-17.2 bar; 0-1724 kPa; 0-17.5 kgf/cm²). Waterproof design with automatic shut-off and valve extension. The quick-locking air line (push-fit gas interface) ensures a secure seal on tire valves and allows hands-free operation while using a tire pump. Long service life: Constructed with high-quality stainless steel and brass components for durability. Compatible with all vehicles including cars, SUVs, trucks, motorcycles, and bicycles. Automatically turns on and off after 20 seconds of inactivity to conserve battery life. Integrated vent valve allows rapid pressure release from overinflated tires. High-quality construction: Noticeable weight due to premium materials. Built with durable stainless steel and brass to withstand pressures up to 250 PSI. Rubber hose is insulated and extra thick for enhanced performance. High precision 250 PSI tire pressure gauge. Measuring range: 0–250 PSI. Accuracy: ±1% + 0.1 PSI. Displays in four units: PSI, BAR, KPA, KG/CM². Button functions: On/Off button (left), unit switch/LED light (right). Compatibility: 1/4" NPT air compressor connection (included). Operating voltage: DC 3.1 V (2 AAA batteries included). Instructions: 1. Remove the valve cap from the tire. 2. Attach the brass tip of the gauge to the tire valve. 3. Read the displayed pressure. 4. Connect an air compressor hose to the inlet and hold the handle to inflate or deflate as needed. 5. Remove the gauge after use and press the bleed valve to reset the display to zero. Includes: 4 valve caps, 1 brass air chuck, 2 AAA batteries, 1 x 1/4" NPT steel fitting, 1 roll of thread sealing tape, 1 pneumatic rotary chuck, 2 sealing O-rings.
