● Comes with all functions and equipment features of the BZ25
● Autonomous long-term recording of carbon dioxide concentration, room temperature and humidity
● Storage for 50,000 measured values
● Freely definable saving interval from 1 second to 12 hours
● USB interface for measuring data transfer
● For table installation and mobile application
● PC analysis software
This CO₂ air quality data logger is the ideal combination measuring device for architects, experts and every heating, ventilation and air conditioning engineer.
The BZ30 provides you with all functions and equipment features of the BZ25 and is further equipped with a large data memory for 50,000 measured values for the long-term recording of carbon dioxide concentrations, air temperature and humidity values in freely definable measuring intervals from 1 second to 12 hours.
The recorded data can be conveniently transferred to the connected PC via a fast USB connection and there analysed and logged using the analysis software included in the scope of delivery.
Owing to the integrated NiMH battery, the BZ30 is also suited for mobile application in addition to the stationary table installation.
The simultaneous recording of humidity and temperature values plus CO₂ concentrations offers property managers or landlords optimal possibilities to monitor the ventilation habits.
