The LEO-Record-H2 is a digital gauge with logging functionality specifically designed for hydrogen applications. It features a stainless steel housing with increased nickel content to reduce embrittlement, and a gold-plated diaphragm to minimize hydrogen diffusion. The device records both pressure and temperature data, with non-volatile memory ensuring data security. It has a long battery life due to low power consumption and an optional intrinsically safe version for explosive environments. The gauge offers a wide range of pressure units, supports 5 user-defined units, and allows simple zero point calibration via buttons. It is suitable for applications in manufacturing, transport, containment/storage, and petrol stations. The device has an accuracy of ±0.05%FS and a total error band of ±0.1%FS, with pressure ranges from -1...3 bar to 0...1000 bar. It also includes a digital LC display with configurable pressure units and a recording function that can be started and stopped manually. The LEO-Record-H2 is available in two variants: one with a rubber cover for additional protection and one with a standard design. It is CE-conformant and meets electromagnetic compatibility standards. The device is suitable for use in harsh environments and can be integrated with software like PressureSuite Desktop for data visualization and export.
