Testo 440 dP Air Flow ComboKit 1 with Bluetooth Anemometer, 50m/s Max, Measures Air Velocity, Humidity, Temperature

Testo 440 delta P Air Flow ComboKit 1 with BluetoothCarry out measurements without any annoying cables: use the kit to handle all relevant measurements in ventilation ducts and at air/ceiling outlets. You will receive the testo 440 dP air velocity and IAQ measuring instrument including differential pressure sensor and the 100 mm vane probe head and hot wire probe head (Ø 9 mm) for attachment to the universal Bluetooth handle supplied. To make measurements more convenient, both probe heads can be combined with the telescope included in the kit. The equipment can be transported safely and conveniently in the robust case. Carry out measurements without any annoying cables thanks to the universal Bluetooth handle: use this practical kit to handle all relevant measurements in ventilation ducts and at air/ceiling outlets. The testo 440 dP multifunction measuring instrument, the vane probe and the hot wire probe head all feature ease of use, maximum convenience for the adjustment of air-conditioning and ventilation systems and an intelligent calibration concept.Features and Benefits• Intuitive: clearly structured measurement menu for volume flow and parallel determination of air velocity, differential pressure, humidity and temperature in ventilation ducts, at ventilation outlets and in work rooms • Space-saving: combine the universal Bluetooth handle with the humidity/temperature probe head or extendable telescope (1.0 m). Vane probe heads (Ø 16 mm, Ø 100 mm) can simply be plugged onto the telescope • Convenient: wireless probes, internal data storage and USB port for data export • As multifaceted as your challenges themselves: the testo 440 dP has an integrated differential pressure sensor and can be expanded with a large portfolio of digital probesTesto 440 delta P Air Flow ComboKit 1 with Bluetooth in detailtesto 440 dP air velocity and IAQ measuring instrument including differential pressure sensor: • With an integrated differential pressure sensor, e.g. for checking filters, for Pitot tube measurement (Pitot tubes can be ordered separately) or K factor measurement • No task is too challenging, no application too specialized: the testo 440 dP combines a compact hand-held measuring instrument with intuitive measurement menus and a wide selection of air velocity and IAQ probes (please order separately) • Clearly structured measurement menus for carrying out measurements in ventilation ducts and at duct/ceiling outlets: the volume flow is precisely calculated thanks to convenient input of the size and geometry of the duct cross-section. Timed and multi-point mean calculation, average volume flow, current reading and min./max. values are displayed • Other practical measurement menus, e.g. determination of volume flow via differential pressure and K factor, long-term measurement, volume flow measurement with a funnel, 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 (e.g. ducts) • Automatic detection of probes, e.g. vane and humidity/temperature probe • Large, backlit colour display Vane probe (Ø 100 mm) with Bluetooth including temperature sensor: • Use the vane probe (Ø 100 mm) to conveniently determine air velocity, volume flow and air temperature at air/ceiling outlets • Measuring range: +0.3 to +35 m/s, -20 to +70 °C • More applications – less equipment: the universal handle on your 100 mm vane probe is easy to attach to other probe heads or telescopes. This allows you to expand your portfolio of probes and save space in the measuring case • Carry out measurements at air/ceiling outlets effortlessly and without using a ladder: simply connect the vane probe to the extendable telescope with 90° angle included in the kit • Wireless: the Bluetooth handle makes it more convenient to carry out your measurements and guarantees less cable clutter in the case • Practical button on the handle: to store individual readings for multi-point mean calculation or to start and stop measurement series for mean calculation over time • Our recommendation for carrying out accurate measurements at plate outlets/ventilation grilles: use the vane probe with the testovent 417 funnel set (available to order separately). If you add in the volume flow straightener (please order separately), you can achieve an impressively high level of precision when carrying out measurements at swirl outlets with turbulent air flow • Intelligent calibration concept: the air velocity and IAQ measuring instrument remains in continuous use, since only the probe head is sent in for calibration 16 mm vane probe head including temperature sensor: • Use the vane probe (Ø 16 mm) to determine the air velocity, volume flow and air temperature in ventilation ducts • Measuring range: +0.6 to +50 m/s, -10 to +70 °C • Convenient measurements in ventilation ducts: the probe head is easy to attach to the robust, non-rotatable telescope (up to 1.0 m) supplied, with easy-to-read scaling and Bluetooth handle • Practical button on the handle: to store individual readings for multi-point mean calculation • Our recommendation for larger ducts: use the telescope extension (available to order separately) – enabling you to attain a total length of 2 metres • Intelligent calibration concept: only the 16 mm vane probe head needs to be sent in for calibrationHumidity/temperature probe head: • 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 • Wireless and space-saving: the probe head is easy to attach to the universal Bluetooth handle included in the kit • Use the practical button on the handle to store individual readings • You only need to send in the humidity/temperature probe head for calibration
