The invention discloses a pressure gauge, and belongs to the technical field of pressure gauges. A pressure gauge comprises a pipeline, a first branch pipe and a second branch pipe, the first branch pipe and the second branch pipe are connected with the pipeline, a cleaning mechanism is installed at the top end of the first branch pipe, a pressure gauge is installed at the top of the second branch pipe, a protection mechanism is arranged outside the pressure gauge, and the cleaning mechanism comprises a second protection shell fixedly installed at the top of the second branch pipe. A slot is formed in one side face of the second protective shell, and a first fixing plate is arranged in the second protective shell on one side of the slot. According to the pressure gauge, reading inconvenience caused by the fact that dust covers the surface of the pressure gauge is prevented, meanwhile, damage to the pressure gauge possibly caused by manual cleaning is avoided, when a cleaning brush needs to be replaced and det
