No task is too challenging, no application too specific - the testo 440 combines a compact handheld measuring instrument with intuitive measurement menus and a wide selection of air velocity and IAQ probes (probes sold separately)
Clearly structured measurement menus for long-term measurement - simply enter the measurement time and measuring cycle and record data trends
Easy storage and evaluation of measurement data - internal memory for up to 7,500 measurement protocols, which can be read via USB port and further processed as a CSV file on the computer (e.g. with Excel)
Practical rear magnets for secure attachment of the measuring instrument to metal surfaces
Automatic detection of probes, e.g. CO₂ probe, turbulence probe
Large, backlit color display

CO₂ probe with Bluetooth and humidity/temperature 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 integrated absolute pressure measurement
Measuring range: 0 to 10,000 ppm, 14 to 122 °F, and 5 to 95% RH
The Bluetooth handle makes it more convenient to carry out your measurements and guarantees less cable clutter in your case - it transmits readings to the testo 440, from up to 65 feet away
Practical button on the handle - for storing individual readings
Versatile - the universal handle can be connected to all probe heads, so you can take care of more applications, and use less equipment
Intelligent calibration concept - the testo 440 remains in continuous use, since only the individual probes need calibration

Turbulence probe with air velocity and temperature sensor:

Use the turbulence probe to measure air velocity and air temperature
Determine the degree of turbulence and draft risk according to EN ISO 7730 / ASHRAE 55
Accurate measurements from 0 to 984.3 fpm within the temperature range 0 to 122 °F, thanks to air density compensation via integrated absolute pressure measurement
Use the measuring tripod for easy positioning of the turbulence probe (sold separately)
Use the fixed cable to connect the turbulence probe to the testo 440
