Testo 440 CO2 Kit with Bluetooth

The testo 440 CO Kit is great for carrying out indoor air quality measurements. The testo 440 air velocity and IAQ measuring instrument and its CO2 probe with humidity/temperature sensor can all be safely stored in the included case.

• Intuitive: Clearly structured measurement menus for long-term measurements 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 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
• Please do not use the probe in condensing atmospheres. For continuous application in high-humidity ranges:
  • 80% RH at ≤ 86 °F for > 12 h
  • 60% RH at > 86 °F for > 12 h
