Description
This instrument measures the percentage of carbon dioxide (CO2) in a gas, such as air.
The UK government recommends that workplaces use CO2 monitors to identify poorly ventilated spaces. People emit CO2 when they breathe out, so build ups indicate a lack of ventilation.
This one was designed for industrial settings, such as power stations or cold storage.
