Testo 440 Indoor Comfort Kit with Bluetooth

The Testo 440 Indoor Comfort Kit is great for evaluating indoor air quality and determining draft risk and degree of turbulence in workplaces. The testo 440 air velocity and IAQ measuring instrument and its CO2 probe with humidity/temperature sensor and turbulence probe can all be safely stored in the included case.

• Intuitive: Clearly structured measurement menus for long-term measurement and parallel determination of CO2 concentration, humidity, air temperature, and degree of turbulence in workplaces
• Precise: Calculation of wet bulb temperature, dew point, and absolute humidity - determination of the degree of turbulence and draft risk according to EN ISO 7730 / ASHRAE 55
• Convenient: Wireless probes, internal memory for data storage, and USB port for data export
• Versatile: Your testo 440 setup can be expanded with a large selection of digital probes

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 - volume flow is calculated precisely, thanks to convenient inputs for the size and geometry of a duct's cross-section. Displays timed and multi-point mean calculation, average volume flow, current reading, and maximum / minimum values
• Other practical measurement menus, e.g. long-term measurement, volume flow measurement with a funnel, etc.
• 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 (e.g. ducts)
• Automatic detection of probes, e.g. hot wire 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
