LEO-Record-H2 / LEO-Record-Ei-H2 – Digital Pressure Gauges for Hydrogen Applications

Product News
26. September 2023

With their long service life and high level of accuracy, the KELLER pressure gauge LEO-Record-H2 and their intrinsically safe ATEX counterparts LEO-Record-Ei-H2 range provide a reliable solution for all hydrogen applications.

The highly accurate, digital pressure gauge LEO-Record-H2 complements the hydrogen portfolio with a display and storage device, which can record pressure and temperature over a longer period of time.

Wetted parts are designed according to the requirements for hydrogen products: Due to the increased nickel content in the stainless steel, the device has a low embrittlement rate, which ensures a long service life. Thanks to its gold-plated membrane, H2 diffusion is reduced to a minimum.

Via the RS485 interface, the pressure gauge can be easily connected to a computer to make configurations or read out the records. With its high accuracy and safety, the LEO-Record-H2 fulfils all requirements for measuring devices in the field of hydrogen.

The KELLER pressure gauges LEO-Record-H2 and LEO-Record-Ei-H2 are used in a wide range of fields, including hydrogen generation and production, in transportation, in the monitoring of hydrogen refuelling stations and in the containment and storage of hydrogen.
