LEO-Record-H2 is a digital gauge with logging function for Hydrogen Applications. The digital manometer includes a higher Nickel content in the Stainless Steel components to lower embrittlement and a Gold plated diaphragm to minimise H2 diffusion. Recording function is the same as the standard LEO Record gauges with the same K114A download cable and Pressure Suite software. Separate LEO-Record-Ei-H2 is available for installations in Hazardous Areas.
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.
