Lanso Instruments Inc. is a Canada-based industrial products manufacturer & supplier specializing in devices to measure pressure. The company's extensive product portfolio and dedication to high-quality products ,such as pressure measurement device,gas density monitor,gas density switch,gas density transmitter,pressure gauge and so on,have earned us high brand recognition and established long-term partnerships with multinational corporations including ABB, HYOSUNG, TOSHIBA, SCHNEIDER, SIEMENS, and so on.

The SF6 gas density meter with pointer and scale installed on the SF6 circuit breaker is called the density meter; SF6 relay or density pressure switch without pointer and scale. Some SF6 gas density meter also has electric contact, which doubles as density relay. They are dedicated meters for measuring SF6 gas.

SF6 circuit breaker, as a new type of high-voltage electrical switching equipment developed in modern times, has been widely used in power system due to its superior performance, safety and reliability, easy maintenance and long service life, etc. A density relay is a relay that monitors air leakage from a sealed container.

Lanso is devoted to developing medium and high-end  SF6 gas density monitor, and manufactures better gas density monitor in the market depending on advanced equipment.
