The Testo 05634404 Bluetooth Humidity Kit is used to measure humidity and temperature in storage, refrigeration, work rooms, and in ventilation ducts. The 440 Air Velocity and IAQ Measuring Instrument and its humidity/temperature probe are easy to use, low maintenance, and maximize convenience.

The 0563 4404 Bluetooth Humidity Kit includes the Testo 440 Air Velocity and IAQ Meter, which combines all the benefits of a compact handheld device with intuitive measurement menus and a comprehensive selection of air velocity and IAQ probes. This means you have all measuring tasks on air conditioning and ventilation systems reliably under control. You can connect the testo 440 to a large selection of digital probes, testo Smart Probes, or even many testo temperature probes, allowing for numerous configurations to meet your needs.

The clearly structured menus for measuring volume flow in ducts and at outlets, cooling/heating load, K-factor, turbulence, mold indication and even a data logging mode are stored on the instrument for additional convenience. These menus enable you to accomplish your measuring tasks more quickly, more efficiently and more reliably than ever before. Reports can also be exported as excel files via the USB interface or printed out directly on site.

Fast and Easy Measurements

Carry out your measurements quickly and easily. This multifunction instrument automatically detects each connected probe, which means you won't need to manually reset measurement parameters when changing probes. Up to 3 probes can be connected simultaneously – a Bluetooth probe, a wired probe, and a temperature probe with a type K thermocouple connector (additional probes sold separately). Clearly structured measurement menus for measuring the volume flow in ducts and at outlets, funnel measurement, measuring the degree of turbulence, determining heating/cooling output, mold detection, and long-term measurement provide you with the optimal support for quick and efficient work.

More Applications, Less Equipment

The universal probe handle can be connected to all probe heads, so you can measure everything you need, while saving money and space. The Bluetooth probe handle makes it more convenient to carry out your measurements, and guarantees less cable clutter in your case. It makes it possible to carry out measurements without any bothersome cable connections, and it transfers readings up to a distance of 65 feet. If using a wireless connection is not possible, use the cable probe handle (sold separately) as a practical alternative.

Practical Data Management.

The testo 440 stores up to 7,500 measurement protocols, which can be read via USB port and further processed as a CSV file on your computer (e.g. with Excel). With the testo Bluetooth / IrDA printer (sold separately), you have the ability to produce a printed report of measurement data directly on site.

Intelligent Calibration Concept for Maximum Precision

You can rely on the accuracy of your measurement results with our digital probes, because the testo 440 makes measurement uncertainty a thing of the past. You only need to send the probes in for calibration, meaning the multifunction instrument can remain in continuous use with a variety of interchangeable probes.
