Renson C02 MONITOR

To measure is to know. There’s no way you can smell deteriorating
air quality, so a reliable monitor is indispensable. If you’re looking
for a pointer on when to ventilate and you’d like to know the exact
extent of the problem, a reliable C02 monitor offers peace of mind
around the home — or in any other space where multiple people
are gathered.

A C02 monitor is an important sensor for the air quality in your home. This type of device accurately measures and reports the concentration of C02 in the air, in parts per million.
If this concentration of C02 starts to rise to dangerous levels, the sensor raises the alarm. That way, you — or your demand-driven ventilation system — know that urgent action is
required to improve your air quality.
