Voltcraft CO-100 Room Air Meter CO-100 Data Sheet

The medium display line can be switched between temperature and ventilation rate
display.

The ventilation rate indicates how much air is recirculated from outside to the inside. This
is calculated from the change of the CO

2

 concentration within a certain period and the

difference to the CO

2

 concentration outside (atmosphere, approx. 400ppm). A low value

corresponds to a bad ventilation rate (low air exchange), a high value to a good ventilation
rate (large air exchange).

¼

A good ventilation rate may also point to waste of energy, e.g. due to windows not
being tight.

For an indicative value, read the values only after 2-3 hours, once the CO

2

 concentration

has stabilised, e.g. after all employees have left the office.

Repeatedly press the arrow „“ or „“ in normal operating mode; the middle display line
switches between the following displays:

• Measured temperature value

• Ventilation rate l/p/s (litres of air per second and person)

• Ventilation rate m³/p/s (cubic metres of air per second and person)
