A building-performance laboratory, in context
Explore an indoor research setting where carbon monoxide and oxygen measurements form part of a wider environmental record. Select a numbered point to explore.
CO and oxygen, side by side
The CO channel spans 0–100 ppm at 0.1 ppm resolution. The O₂ channel spans 0–25% by volume at 0.01% by volume resolution.
The whole indoor picture
Every variant also includes CO₂, PM1.0, PM2.5, PM10, temperature and humidity. Review these measurements together to give your gas observations more context.
A record you can revisit
A built-in data logger offers storage intervals programmable in one-minute steps. Access historical data and generate reports for analysis and sharing.
Building-performance research
Include both carbon monoxide and oxygen in an indoor monitoring study.
