膜盒壓力表適用于測量對銅合金不起腐蝕作用，無爆炸危險的微壓和負壓。

    廣泛應用于鍋爐通風、氣體管道、燃燒裝置等其他類似設備上。

The bellows pressure gauge is suitable for measuring the micro pressure and negative 

pressure of copper alloy without corrosion and explosion danger. Widely used in boiler 

ventilation, gas pipes, combustion equipment and other similar equipment.
