Vision CO2 Monitor for Schools & Offices : Plug-in

162.00 excl. VAT


The Vision CO2 Monitor is a high-quality CO2, Relative Humidity & Temperature Monitor. This USB powered device provides a cost effective ‘plug and play’ solution to help determine if further ventilation is required by providing a clear digital readout with a simple to understand traffic light backlit display.

There is approx. 400 ppm CO2 in outdoor air and we breathe out approximately 40,000 ppm with each breath, so CO2 is the most reliable proxy for poor ventilation available in occupied spaces.
Elevated CO2 levels not only provide an indication that airborne contaminants may be present, they also reduce cognitive function, productivity and can have long term adverse effects on health and wellbeing.


Helping reduce the relative risk of the airborne transmission


With the current pandemic, ventilation is one of the most important factors in helping reduce the relative risk of the airborne transmission of COVID-19, which is why CO2 Monitors have been recommended as an indicator of poor ventilation by the Scientific Advisory Group for Emergencies (SAGE) and the Chartered Institute of Building Services Engineers (CIBSIE)
Most buildings are naturally ventilated and rely on opening windows for fresh air, or use air recirculation systems that have been switched on, so without a CO2 monitor there is no way of knowing if spaces such as classrooms and offices are adequately ventilated. The Vision CO2 Monitor removes any uncertainty and provides an immediate indication that further ventilation is needed.
