BZ30 CO₂ Air Quality Data Logger

For autonomous long-term recording of indoor air quality

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 Li-Ion 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.

A few practical benefits:

  • Accurate and permanently stable NDIR measurement of carbon dioxide concentrations in the room air
  • Simultaneous display of CO₂ values, room temperature, humidity, date and time
  • Minimum and maximum value function for CO₂, air temperature and humidity
  • Carbon dioxide alarm function with acoustic alarm signal for freely definable limit values
  • Additional symbolic CO₂ indicator display
  • Large backlit display with easily legible measured value indication
  • 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
  • Free standing or wall mounted
  • PC analysis software

CO2-Luftqualitätsdatenlogger BZ30

Ein komplizierter Name für ein simples wie cleveres Prinzip: Der BZ30 misst nicht nur CO2-Konzentration, Temperatur und Luftfeuchtigkeit im Raum, sondern speichert die Daten auch. So sind unbeaufsichtigte Langzeitmessungen möglich.

CO2-Luftqualitätsmonitor BZ25

Unmotiviertes Herumkritzeln auf dem Notizblock statt effizienter Arbeit – kennen Sie das? Diese Motivationslöcher finden ihre Ursache häufig in schlechter Luftqualität. Zu viel CO2 verursacht u.a. Müdigkeit.
