The testo 440 Humidity Kit is great for carrying out measurements in storage, refrigeration, and work rooms, in ventilation ducts, and also on refrigeration systems and heat pumps. The testo 440 air velocity and IAQ measuring instrument and its humidity/temperature probe (Ø 0.47") with temperature sensor can all be safely stored in the included case.
- Intuitive: Clearly structured measurement menus for long-term measurements and parallel determination of humidity and air temperature in storage, refrigerated, and work rooms, and in ventilation ducts
- Precise: Calculate dew point, wet bulb temperature, 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
The testo 440 humidity kit with Bluetooth in detail
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. humidity/temperature probe
- Large, backlit color display
Humidity/temperature probe (Ø 0.47") with Bluetooth:
- Use the humidity/temperature probe to measure relative humidity and air temperature, and to calculate dew point, wet bulb temperature, absolute humidity, and heating/cooling output
- Reliable measurement results, thanks to a high quality, long-term, stable humidity sensor
- Measuring range: 0 to 100% RH and -4 to +158 °F, accuracy of ±2% RH and ±0.9 °F
- Versatile - the universal handle can be connected to all probe heads, so you can take care of more applications, and use less equipment
- 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
- 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

The intuitive measurement menus: suitable for any application.
Based on Testo's many years of experience in the development of cutting-edge measuring technology, they know precisely what you need to carry out your routine work. This is why measurement menus for the essential air conditioning and ventilation applications are already pre-stored in the testo 440. These menus enable you to accomplish the relevant measuring task more quickly, more efficiently and more reliably.
The testo 440 probe system: you'll never want to work any other way again.
Completely versatile: a universal handle for all air velocity & IAQ probes. This saves space and reduces the weight, enabling you to perform accurate measurements in any application. With the testo 440, you have all air conditioning and ventilation measurements systematically under control.
