Testo, 0563 4404, 440 Humidity Kit with Bluetooth, 440 Air Velocity and Humidity Probe
This testo 440 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.
Use this practical kit to measure the humidity and temperature in storage, refrigeration, and work rooms, and in ventilation ducts. The testo 440 multifunction measuring instrument and its humidity/temperature probe are low maintenance, easy to use, and maximize convenience.
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
Features:
- 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
Includes:
- testo 440 air velocity and IAQ measuring instrument, 3 AA batteries, USB cable, and calibration protocol (0560 4401)
- Humidity/temperature probe (Ø 0.47") with Bluetooth* (consisting of humidity/temperature probe head and Bluetooth handle), 4 AA batteries, and calibration protocol (0636 9731)
- Basic case for testo 440 and 1 probe
*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
