NEW! VOCOOnx – Mobile air sensor technology. Everywhere. In real time.
How clean is the air that we and our employees actually breathe?
Whether in the office, factory, or outdoors—air quality is crucial, but often remains invisible. VOCOOnx makes precisely these pollutants visible: mobile, understandable, and ready to use.
Developed for mobile use
With VOCOOnx, ELK GmbH brings a consistently mobile solution to air and indoor climate measurement. The smallest mobile 5-in-1 professional sensor in its class was developed specifically for changing locations – without installation, without fixed infrastructure.
VOCOOnx – Real-time air quality monitoring:
- CO₂ - Carbon dioxide
- Particulate matter PM1, PM2.5, PM4 (A-dust), PM10
- CO - Carbon monoxide
- TVOC indicator – Volatile organic compounds
- NOx indicator – Nitrogen oxides
Makes visible what otherwise remains invisible – anytime, anywhere.
Mobile measurement – no effort required
VOCOOnx is ready for immediate use:
- Wireless & battery-powered
- No installation or network required
- Ideal for inspections, spot checks, and outdoor use
- Flexible use in offices, industry, workshops, or outdoors
- Cloud and app connectivity
- Live data, history and export – available anytime, anywhere
LED traffic lights, an integrated display, and app connectivity ensure that measurement results are easy to understand at a glance—even without prior knowledge.
“We wanted to develop a device that shows occupational health and safety managers exactly what their teams are breathing – mobile, without technical complexity, and highly informative,” explains Mehmet Parmak from the BAPPU team.
Now available to order – delivery from March
The VOCOOnx is now available to order.
Delivery will start in March, allowing companies to plan ahead and implement targeted measures to improve air quality.

Measure. Understand. Document.
In combination with BAPPUnow, the powerful online software for managing devices, measurement data, and locations, mobile measurements can be used directly—for example, as a basis for risk assessments, for documentation, or for the sustainable optimization of the working environment.
VOCOOnx stands for modern air measurement technology that adapts to everyday working life: small, wireless, and unstoppable.
