The PCL Air Technology Accura MK4 Tire Inflator combines the ruggedness of a metal analog inflator with the accuracy and ease of use of a digital gauge. The hand-held tire inflator offers a large LCD backlit screen that is easy to read at night or in the dimly lit areas. Users can easily toggle between different pressure calibration units such as psi, bar, and kPa. With a reading accuracy of 0.1 psi, each unit is individually tested and includes a calibration certificate.
