A pressure washer gauge can come in handy when you want to measure the amount of pressure released from your machine's pump. Our PSI gauges have a pressure scale of 4200 PSI and 6000 PSI. This means that you can know the amount of pressure generated both in small and largescale projects. Despite measuring pressure levels, our gauges can serve as a visual confirmation of a change in pressure levels. When shopping for a power washer pressure gauge from Hot Power Washers, you need to evaluate factors like: ● Connection type and size ● Connection material ● Measuring range ● Maximum operating temperature
