Intuitive: clearly structured measurement menu for long-term measurement and parallel determination of CO₂ concentration, humidity and air temperature in indoor areas -
Precise: absolute pressure compensation, calculation of wet bulb temperature, dew point and absolute humidity -
Convenient: wireless probe, internal data storage and USB port for data export -
As multifaceted as your challenges themselves: the air velocity and IAQ measuring instrument can be expanded with a large portfolio of digital probes
Kit for evaluating the indoor air quality. The testo 440 air velocity and IAQ measuring instrument and the CO2 probe with Bluetooth including temperature and humidity sensor are all safely stowed away in the case. So you can get down to work straight away!
Product Description
Use this practical kit to measure CO2 concentration, humidity and air temperature and to evaluate the indoor air quality in offices, production areas or storage facilities. The multifunction measuring instrument and the CO2 probe feature an intelligent calibration concept, ease of use and maximum convenience for your measuring tasks.
testo 440 CO2 Kit with Bluetooth in detail
testo 440 air velocity and IAQ measuring instrument:
-
No task is too challenging, no application too specialized: the testo 440 combines a compact hand-held measuring instrument with intuitive measurement menus and a wide selection of air velocity and IAQ probes -
Clearly structured measurement menu for long-term measurement: for long-term monitoring, enter the measurement time and measuring cycle in the measuring instrument and record measurement data trends -
Easy storage and evaluation of measurement data. Measurement data memory for up to 7500 measurement protocols, which can be read via a USB port and further processed as a CSV file on the computer (e.g. with Excel) -
Practical magnets for easy attachment of the measuring instrument to metal surfaces -
Automatic detection of probes, e.g. CO2 probe -
Large, backlit colour display
CO2 probe with Bluetooth, including temperature and humidity sensor:
-
Measure CO2 concentration, humidity and air temperature and calculate dew point, wet bulb temperature and absolute humidity -
Accurate measurement results thanks to air density compensation via the integrated absolute pressure measurement -
Measuring range: 0 to 10,000 ppm, -10 to +50 °C, 5 to 95% RH -
The Bluetooth handle makes it more convenient to carry out your measurements and guarantees less cable clutter in the case -
Practical button on the handle: to store individual readings -
Endlessly versatile: a universal handle can be connected to all probe heads – so you can take care of more applications using less equipment, and save space too -
Intelligent calibration concept: the measuring instrument remains in continuous use, since only the probe head is sent in for calibration
