KM type switchgear barometer

The KM type switchgear barometer is a critical device for ensuring the stable operation of power systems. It accurately monitors the gas pressure inside switchgear with high sensitivity and reliability, providing real - time feedback on abnormal pressure conditions. This effectively prevents equipment failures caused by insufficient air pressure. Widely used in various power switchgear, it offers a solid guarantee for the safe operation of electrical equipment.
