Detect leaks before they become a problem.

Continuous monitoring instead of periodic inspections.
Regular LDAR inspections reach their limits when leaks occur between inspection intervals. The atmio SLD closes this gap: Permanently installed, it detects methane from 0.5 ppm and reports anomalies, so your team only takes action when truly necessary.
Developed for automated leak detection and site measurements.
The atmio SLD combines highly sensitive sensor technology with a low-maintenance design for reliable 24/7 monitoring without on-site IT infrastructure.
The SLD's semiconductor sensor detects methane concentrations as low as 0.5 ppm — well below the regulatory repair threshold and the typical detection limit of other stationary systems.
Installation in minutes. One sensor per 100 m² of plant area is recommended. The atmio team assists with planning the exact positioning.
No complex wiring, no frequent battery replacement. The SLD operates with low maintenance for several years in continuous operation.
The SLD meets the requirements for use in hazardous areas (Zone 2), ensuring safe operation in gas facilities.
Measurement data is transmitted directly to atmio OS via mobile network, without local infrastructure or on-site IT effort.
Any exceedance of a configurable threshold is highlighted with a colored status in atmio OS. For immediate overview and targeted action.

Three steps to full compliance.
The SLD measures regularly. If a threshold is exceeded, atmio OS automatically flags a potential leak.
You receive a signal and locate the source with the atmio HLD – only when there's a genuine suspicion.
All events are documented and automatically included in the emissions report.
Developed for the requirements of the EU Methane Regulation.
The EU Methane Regulation explicitly provides that advanced LDAR technologies can be used to adjust the frequency of manual inspections. The atmio SLD has been validated in active pilot projects, including one with Netze BW.

„Die Kombination aus atmio und Bohlen & Doyen hilft uns, alle Anforderungen der EU-Methanverordnung termingerecht und zuverlässig umzusetzen. Das Zusammenspiel aus präziser Messtechnik und digitaler Dokumentation erleichtert unsere Arbeit deutlich.“
„atmio hat uns in kürzester Zeit geholfen, die Anforderungen der Methanverordnung vollumfänglich zu meistern. Besonders schätzen wir die intuitive Bedienung, die erhebliche Zeitersparnis und den verlässlichen Support.“
"Durch die Implementierung der Lösung von atmio können wir Prozesse für Leak Detection and Repair effizient und systematisch im Betrieb umsetzen und sind damit bestens gewappnet für die neue EU-Methanverordnung."
"Die Monteure sind nicht dafür da, den ganzen Tag Papier auszufüllen, sondern sich um Instandhaltungen, Wartung und Reparaturen zu kümmern. Unser Ziel ist, Methanemissionen zu verringern und den bürokratischen Aufwand so gering wie möglich zu halten. Durch atmio schaffen wir genau das: Methanemissionen verringern und bürokratischen Aufwand zu gering wie möglich zu halten."

Frequently Asked Questions
Here you will find answers to the most frequently asked questions about the atmio SLD: so you can understand how permanent leak monitoring works, what the three indications mean, and what to expect after installation.
Not directly – but it changes when it's needed. Instead of fixed inspection intervals, the SLD enables a risk-based approach: an inspection is only triggered when the SLD indicates a deviation. A rigid cycle becomes a demand-driven inspection.
No Leak – signal within learned normal range, no action required.
Potential Leak – deviation from baseline, visit at the next opportunity and perform an LDAR measurement.
Leak – confirmed deviation, promptly locate and seal the potential leak.
No. The system uses Gaussian processes to learn the leak-free normal signal of each facility. A leak is detected by a combination of absolute level, rate of increase, short-term and long-term trends, and signal residual – summarized into a confidence value. Thresholds are automatically derived from a reference period, not set manually.
That depends on the responsible authority. The SLD is validated for detecting leaks from Type-2 repair thresholds (~500 ppm / ~1 g/h). Whether it is officially accepted as a detection method must be clarified individually – this issue is still open.
