Whether gas, water or sewage networks: anyone responsible for critical infrastructure needs reliable and practical measurement technology. Our OLLI devices offer exactly that – in several specialised versions for different applications.

Measuring and testing with our OLLIs: we present them in a practical and solution-oriented way.

Safe shaft inspection and clearance measurement with OLLI

When entering shafts and confined spaces – for example, in gas, water or sewage infrastructure – there is a potential risk to life due to toxic or explosive gas atmospheres. According to DGUV Rule 113-004 (Germany), a so-called clearance measurement is mandatory before starting work in order to rule out hazards due to oxygen deficiency, toxic gases or explosive atmospheres.

OLLI-Schachtwarn

OLLI as a personal gas detection device

The OLLI is our compact, explosion-proof pump or diffusion handheld measuring device for continuous monitoring of the atmosphere. It measures up to five gases simultaneously – including oxygen and combustible and toxic gases (e.g. H₂S, CO, CO₂) – and provides reliable warnings in case of danger.

Application and advantages:

  • Use as a diffusion device or with integrated pump
  • Robust 2K plastic housing and explosion-proof Li-ion battery
  • Intuitive operation with menu navigation in accordance with DVGW worksheet G 465-4 (Germany)
  • Practical additional functions such as automatic start in the last operating mode
    Wireless data transfer for easy documentation
  • Ideal for utilities, construction companies and anyone working in confined spaces

Documentation during flaring of residual gases with OLLI

When flushing and decommissioning pipelines, residual gas is produced that must be flared. Network operators face the challenge of documenting the exact amount of methane flared – especially in the context of the new EU Methane Regulation. Compliance with this regulation is crucial for transparency and sustainability.

The OLLI with pressure measurement for measuring gas volume

The OLLI can also be configured with a precise pressure sensor. In combination with our Mobile Gas Flares, it accurately measures the amount of methane or propane flared – and thus provides all the data required for legal documentation in accordance with the EU Methane Regulation.

Application and advantages:

Precise leak detection in water pipes with OLLI tracer gas

Water losses due to leaks in drinking water pipes and domestic plumbing are not only economically problematic, but also environmentally damaging. Conventional acoustic methods often reach their limits when it comes to very small leaks.

OLLI Tracergas

The OLLI tracer gas for leak detection with forming gas

The OLLI Tracergas is a specialised gas detection device for locating even the smallest leaks using forming gas (5% hydrogen, 95% nitrogen). This method is particularly gentle, effective and economical – and also works in complex pipe systems.

Application and advantages:

  • For leak detection in drinking water, heating and cooling systems as well as automotive air conditioning systems
  • Use of different probes thanks to integrated pump
  • Detection by suction of the gas and highly sensitive sensor technology
  • Robust housing, intuitive menu navigation and wireless data transmission
  • Particularly interesting for the construction industry, installers and municipal utilities

Whether personal protection, residual gas documentation or precise leak detection: our OLLIs offer the right solution for every application.

All variants are based on a practical, robust concept and can be flexibly configured.
