KELLER LEO-Record-H2 / LEO-Record-Ei-H2: Digital pressure gauges for hydrogen applications
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 areused 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.
KELLER LEO-Record-H2 offers:
•Pressure and temperature recording
•Selected stainless steel alloy for minimal material embrittlement
•Gold-plated diaphragm for reduced hydrogen diffusion
•Non-volatile memory ensures a high degree of data security
•Long battery life thanks to very low power consumption
•Intrinsically safe ATEX version available
THE COMPANY
Founded in 1974 by physicist Hannes W. Keller in Winterthur, Switzerland, KELLER Pressure is a leader in high-precision pressure measurement technology. By the 1980s, KELLER had become an established supplier of OEM pressure transducers in international markets. Today, under the leadership of Tobias and Mike Keller, the company maintains its headquarters and production facilities in Winterthur, producing over 1.3 million measuring cells annually.
KELLER’s products—pressure transmitters, transducers, gauges, and more—are used across industries such as aviation, oil and gas, and groundwater measurement. With 500 employees, 13 subsidiaries, and 30 representatives globally, KELLER is synonymous with the “Swiss Made” label for precision and quality.
Looking ahead, KELLER focuses on flexibility for OEM clients, digital transformation, and growth in the semiconductor industry. By 2026, the company will move production to its new 12,000 square meter facility, “Diamant,” in Winterthur.
