The testo 440 Air Flow ComboKit 2 for carrying out measurements in ventilation ducts and at air outlets. Includes the testo 440 air velocity and IAQ measuring instrument, vane probes and combi-case. The testo 440 is a wireless air velocity meter provides structured measurement menus for volume flow and determination of air velocity, humidity, and temperature in ventilation ducts. Includes two testo wireless vane probes with different sizes to meet all workplace needs. Use the testo 440 air velocity and IAQ measuring instrument in combination with high-quality probes to measure and store all air velocity and IAQ parameters (please order probes separately). Up to 3 probes can be connected simultaneously: a Bluetooth probe, a wired probe and a temperature probe with type K thermocouple connector. Automatic probe detection and clearly structured measurement menus guarantee simple operation and will make your day-to-day work easier. 3 Year Warranty (2 Year Manufacturer Warranty + Bonus 1 Year Instrument Choice Warranty)0563-4407 Features- Large range of connectable probes, hot wire and vane probe ( 16 mm) for measurements in ducts; large vane probes of 100 mm for measurements at air/ceiling outlets- Calculate volume flow quickly. On the measurement menu, simply configure the dimensions and geometry of the duct cross-section and see the volume flow displayed on the measuring instrument straight away- You will even find it easy to carry out measurements in particularly large ducts. This is because the extendable telescope on the hot wire and vane probe ( 16 mm) with universal handle can be further extended using the telescope extension enabling you to attain a total length of 2 metres- Carry out measurements at air/ceiling outlets effortlessly and without using a ladder. Fit the vane probe (100 mm radius) with the extendable telescope with 90 angle and, if necessary, with the telescope extension (both can be ordered separately)- Use the vane probes in conjunction with the testovent measurement funnels and flow straighteners to test incoming / outgoing air at plate outlets, ventilation grilles and swirl outlets- Practical Bluetooth interface and use the air velocity probes to measure without having to deal with any bothersome cables, operate the measuring instrument by pressing the button on the handle of the probe, e.g. start or stop a timed mean calculation- Use the practical magnets to securely attach the multifunction measuring instrument to metal surfaces (e.g. ventilation ducts)Standard package includes: - Testo 440 air velocity and IAQ measuring instrument, 3 x AA batteries, USB cable and calibration protocol (0560 4401)- Vane probe (100 mm diameter) with Bluetooth including temperature sensor (consisting of 100 mm vane probe head, handle adapter and Bluetooth handle); bracket for testovent measurement funnel, 4 x AA batteries and calibration protocol (0635 9431)- Vane probe (16 mm diameter) with fixed cable (cable length 1.7 m), including telescope (can be extended to 0.85 m) and calibration protocol (0635 9532)- Combi-case for testo 440 and multiple probes (0516 4401)
