Testo 440 Humidity Kit with Bluetooth
 
 
Intuitive: Clearly structured measurement menu for long-term measurements and parallel determination of humidity and air temperature in storage, refrigerated and work rooms, and ventilation ducts.
 
Precise: Automatic calculation of dew point, wet bulb temperature and absolute humidity.
 
Convenient: Wireless probe, internal data storage and USB port for seamless data export.
 
Versatile: 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 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 and ease of use.
 
Testo 440 Humidity Kit with Bluetooth in detail
 
Testo 440 air velocity and IAQ measuring instrument:
 
 
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: Enter the measurement time and measuring cycle to record measurement data trends.
 
Other practical measurement menus included: Determining the cooling/heating output, mould detection, and more.
 
Easy storage and evaluation of measurement data: Memory for up to 7,500 measurement protocols, readable via USB port as a CSV file (e.g., for Excel).
 
Practical magnets for easy attachment of the measuring instrument to metal surfaces.
 
Automatic detection of probes and a large, backlit colour display.
 
 
Humidity/temperature probe with Bluetooth:
 
 
Accurately measure relative humidity and air temperature; 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, saving space and equipment.
 
The Bluetooth handle transmits readings to the instrument from up to 20 m away, eliminating cable clutter.
 
Practical button on the handle for storing individual readings directly.
 
Intelligent calibration concept: Only the humidity/temperature probe head needs to be sent for calibration.
