testo 440 Humidity Kit with Bluetooth�
 
Intuitive: clearly structured measurement menu for long-term measurements as well as the parallel determination of humidity and air temperature in storage, refrigerated and work rooms and also in ventilation ducts
Precise: calculation of dew point, wet bulb temperature and absolute humidity
Convenient: wireless probe, internal data storage and USB port for data export
As multifaceted as your challenges themselves: the air velocity and IAQ measuring instrument can be expanded with a large portfolio of digital probes
Kit for carrying out measurements in storage, refrigeration and work rooms, in ventilation ducts and also on refrigeration systems and heat pumps. Keep the testo 440 air velocity and IAQ measuring instrument and the humidity/temperature probe with Bluetooth safely stowed away in the case. So you can get down to work straight away
Product Description

Use this practical kit to measure the humidity and temperature in storage, refrigerated and work rooms as well as in ventilation ducts. The testo 440 multifunction measuring instrument and the humidity/temperature probe are impressive thanks to their intelligent calibration concept, ease of use and maximum convenience for your measuring tasks.

testo 440 Humidity Kit with Bluetooth in detail

testo 440 air velocity and IAQ measuring instrument:
 
No task is too challenging, no application too specialized: the testo 440 combines a compact hand-held measuring instrument with intuitive measurement menus and a wide selection of air velocity and IAQ probes

Clearly structured measurement menu for long-term measurement: for long-term monitoring, enter the measurement time and measuring cycle in the measuring instrument and record measurement data trends. Other practical measurement menus, e.g. determining the cooling/heating output, mould detection, etc.

Easy storage and evaluation of measurement data. Measurement data memory for up to 7500 measurement protocols, which can be read via a USB port and further processed as a CSV file on the computer (e.g. with Excel)

Practical magnets for easy attachment of the measuring instrument to metal surfaces

Automatic detection of probes, e.g. humidity/temperature probe

Large, backlit colour display
Humidity/temperature probe with Bluetooth:

Use the humidity/temperature probe to accurately 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 / -20 to +70 �C, accuracy: �2% RH / �0.5 �C
Endlessly versatile: a universal handle can be connected to all probe heads � so you can take care of more applications using less equipment, and save space too
The Bluetooth handle makes it more convenient to carry out your measurement and guarantees less cable clutter in the case. It transmits the readings to the testo 440 air velocity and IAQ measuring instrument, from up to 20 m away
Practical button on the handle: for storing individual readings
Intelligent calibration concept: the testo 440 air velocity and IAQ measuring instrument remains in continuous use, since only the humidity/temperature probe head needs to be sent in for calibration
