Use this practical kit to handle all relevant measurements when evaluating indoor air quality, and when determining the draft risk and degree of turbulence in workplaces. The testo 440 multifunction measuring instrument and its probes are low maintenance, easy to use, and maximize convenience.
testo 440 air velocity and IAQ measuring instrument:
- 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
