Description
Hydrogen measurement and detection with our OLLI H2 gas detection, warning and measurement device.
The OLLI H2 is an explosion-proof, multifunctional device for the detection, monitoring and measurement of hydrogen (H2) up to 100 Vol.-%. It has been developed for applications where hydrogen is used as an energy or process gas and where the highest standards of safety and regulatory compliance apply. The OLLI H2 is ATEX-certified for use in potentially explosive atmospheres of equipment group IIC.
The device is operated using an integrated pump. The reliable and intuitive menu navigation allows various tests to be selected safely, including monitoring of the working area, purging to check gas purity in relevant pipes, or, optionally, V-measurement for the flaring process and volume measurement of hydrogen.

Challenge
Hydrogen, due to its physical properties, places particular demands on measurement and testing technology and their safety concepts: high diffusivity and low density, increasing regulatory and standard requirements, as well as separate testing procedures when converting existing gas infrastructure.
The OLLI H2 as a solution
The OLLI H2 enables typical applications such as workplace monitoring, building inspections, measurements on exposed pipes, as well as soil gas testing and checking gas purity during purging.
The use of the OLLI H2 is further simplified by the paperless management of measurement results via Esders Connect. Our app makes your documentation faster and clearer, transmits measurement results directly to the office via mobile devices, and automatically sends completed reports to up to three recipients. The solution is GDPR-compliant and offers you location-independent data management. Thanks to the browser-based architecture, there is no need for tedious installations or updates. This means you are always working with state-of-the-art technology.
