Description
The LEO-Record-H2 is a precise digital pressure gauge suitable for Hydrogen systems. Providing long-term pressure and temperature recording with integrated display and storage. Its durable design, featuring high Nickel stainless steel and a Gold-plated membrane, minimises embrittlement and Hydrogen diffusion, ensuring extended service life. Ideal for manufacturing, Transportation, Storage or Forecourt applications.
Features
- Stainless steel with increased nickel content for a lower embrittlement rate
- Gold-plated diaphragm for minimal H2 diffusion
- Pressure and temperature recording
- Non-volatile memory ensures a high degree of data security
- Long battery life thanks to very low power consumption
- Optional: Intrinsically safe LEO-Record-Ei-H2 version available for use in explosive environments
