BZ30 CO2 Air Quality Data Logger
For autonomous long-term recording of indoor air quality
Autonomous long-term recording of carbon dioxide concentration, room temperature and humidity
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.
Automatic baseline calibration
The expected CO2 fresh air value is about 400 ppm (0.04 %vol) nowadays. The device assumes this value to be the lowest limit value (baseline). Over several days, a special algorithm now permanently checks the lowest CO2 value measured of the sensor over a preconfigured time interval and slowly corrects every long-term drift determined by comparison with the expected fresh air value of 400 ppm (or 0.04%vol) CO2. In normal indoor applications, the carbon dioxide level usually decreases almost to outdoor air level at some point during one week. By recording the values over a period of 8 days and then comparing the lowest value to the 400 pm point, the device determines whether or not it needs to adjust the zero point. This takes place fully automatically. The algorithm therefore makes use of the fact that the CO2 content in buildings and rooms regularly stabilises at a minimum for a certain period of time when they are not occupied. In rooms that are continuously occupied or where there is a constantly increased CO2 concentration (e.g. in greenhouses), this principle of automatic balancing therefore does not work.
BZ30 – Special equipment features
Accurate and permanently stable NDIR measurement of carbon dioxide concentrations in the room air
Certified safety - factory calibration of measuring devices directly from the manufacturer
As one of the leading full-range suppliers of measuring equipment for building diagnostics and environmental technology, Trotec offers you the opportunity to have all measuring devices calibrated, maintained and repaired from a single source. With a calibrated measuring device, you avoid inaccurate measurement results and can reliably protect yourself against possible recourse claims. So play it safe and use our calibration service for your Trotec measuring devices: In our in-house laboratory, we calibrate according to the factory standard to firmly defined measuring ranges and points. Optionally, the calibration points can also be individually defined within the specified calibration range.
