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
