Description from Dakota Digital:

The ODY-19-6 Quad Air Pressure gauge can monitor and simultaneously display the front and rear pressure on front/ rear or four wheel independent air ride systems to display each air bag for proper pressure. The ODY-19-6 also displays the air tank pressure with other readings.

Dakota Digital instruments offer a high brightness, vacuum fluorescent display for excellent daytime visibility and a lifetime of trouble free use. Dakota Digital instruments are fully backed by a Limited 24-month Warranty against manufacturer defects and provide the accuracy and performance you've come to expect from Dakota Digital!
