Mini Carbon Dioxide Monitor
How fresh is the air you're breathing?
These cute little handheld CO2 monitors let you know.
Outdoor air has a CO2 level of around 400 to 450ppm
Acceptable indoor air levels in most countries are indicated below 800ppm.
The CO2 monitor provides a continuous readout of CO2 levels and alarms when they exceed 1000ppm.
They measure carbon dioxide levels using NDIR (non-dispersive infra-red) technology, update every 3 seconds, are rechargeable using the included C adaptor cable and at 78g weigh as little as a chicken egg.
