The invention discloses a double-surface indication pressure meter which comprises a pressure meter shell. A heat insulating shell is fixedly connected on the outer wall of the pressure meter shell, a containing shell is fixedly connected at the top of the heat insulating shell and communicated with the heat insulating shell, a communication opening is formed in the top of the pressure meter shell, the pressure meter shell is communicated with the heat insulating shell through the communication opening, an air inlet device is arranged in the containing shell, and a ventilation hole is formed in the top of the containing shell. The double-surface indication pressure meter is provided with the air inlet device, electric heating wires, a treatment device, a first feedback module, a second feedback module, a first comparison module, a second comparison module, a first temperature sensor and a second temperature sensor, so that the temperature in the pressure meter can be detected, heating treatment is performed when the temperature is lower, the pressure meter can work under suitable temperature, detection errors of the pressure meter can be reduced, numerical values can be accurately detected by the pressure meter, and use of people is facilitated.
