Testo 440 Indoor Comfort ComboKit with Bluetooth

Intuitive: Clearly structured measurement menu 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 draught risk according to EN ISO 7730 / ASHRAE 55.
Convenient: Wireless probe, internal data storage and USB port for seamless data export.
Versatile: The hand-held measuring instrument can be expanded with a wide portfolio of digital IAQ probes.

Use this practical Indoor Comfort ComboKit to handle all relevant measurements for evaluating indoor air quality and determining draught risk in workplaces. The kit includes the testo 440 measuring instrument, a CO₂ probe with Bluetooth (including temperature and humidity sensors), and a turbulence probe, all safely stowed in a robust combi-case.
Product Description
This kit is designed to help you evaluate indoor air quality and comfort levels in accordance with international standards. The multifunction measuring instrument and its probes feature an intelligent calibration concept and maximum ease of use for complex comfort level measurements.
Testo 440 Indoor Comfort ComboKit with Bluetooth in detail
testo 440 air velocity and IAQ measuring instrument:

Combines a compact hand-held design with intuitive menus for air velocity and IAQ applications.
Programmed menu guidance allows you to determine degree of turbulence and draught risk easily in accordance with EN ISO 7730 and ASHRAE 55.
Long-term monitoring: Enter measurement time and cycles to record data trends.
Internal memory for up to 7,500 protocols, exportable as CSV files via USB.
Features integrated magnets for easy attachment to metal surfaces and a large, backlit colour display.

CO₂ probe with Bluetooth, including temperature and humidity sensor:

Measure CO₂ concentration, humidity, and air temperature; calculate dew point, wet bulb temperature, and absolute humidity.
Measuring range: 0 to 10,000 ppm, -10 to +50 °C, 5 to 95% RH.
The Bluetooth handle transmits readings from up to 20 m away, reducing cable clutter.
Features a practical button on the handle to store individual readings directly.
Universal handle system: Connect different probe heads to the same handle to save space.

Turbulence probe including air velocity and temperature sensor:

Measure air velocity and air temperature to determine draught risk according to standards.
Accurate measurements from 0 to +5 m/s within 0 to +50 °C.
Includes air density compensation via integrated absolute pressure measurement.
Fixed cable connection ensures stable data transmission for sensitive turbulence measurements.
Intelligent calibration: Only the probe requires calibration, leaving the instrument available for other tasks.
