These gauges and inflators read in Absolute Pressure and are temperature compensated. Absolute pressure readings meaning any atmospheric pressure differences, such as between being at sea level and being at the top of a mountain do not affect the readings. Temperature compensation is also included allowing for gauge readings in the middle of Summer to the middle of winter.
Many Tire Pressure Monitoring Systems work on "Absolute Pressure", which means atmospheric pressures do not affect them. This means you can get different readings from regular tire gauges when comparing to TPMS systems.
The new gauges from Promaster also have an ingress protection rating of IP65 for harsh environments.
Product is perfect for Tire Shops, Repair Shops, Cars, Large Trucks, RVs, Race Cars, Motorcycles, Industrial and Off-Road vehicles. Promaster-Gauges is a division of HawksHead Systems a leading supplier of aftermarket TPMS systems based out of the Vancouver, BC area.
The new gauges are backed by a 5 year warranty and come complete with their own protective storage bag to protect the gauge while not in use.
