Ideal for air outlets in cleanrooms: use the high-precision vane probe (with the compatible measuring instrument) to measure even the lowest air velocities and volume flows as well as the temperature.

Use the vane probe to determine air velocity, volume flow and temperature at air outlets, as well as at plate outlets, ventilation grilles or swirl outlets. The readings are transmitted directly to your measuring instrument via Bluetooth, making your measurements particularly convenient.

Use the vane probe to determine air velocity, volume flow and temperature at air outlets, as well as at plate outlets, ventilation grilles or swirl outlets.

Kit for carrying out measurements at air outlets: the testo 440 air velocity and IAQ measuring instrument and the vane probe (Ø 100 mm) with Bluetooth&reg; including temperature sensor are all safely stowed away in the case. So you can get down to work straight away!

Kit for carrying out measurements in ventilation ducts and at air outlets: The testo 440 air velocity and IAQ measuring instrument, the vane probe (Ø 100 mm) with Bluetooth&reg; including temperature sensor and the hot wire probe including temperature sensor are all safely stowed away in the case. So you can get down to work straight away!

Kit for carrying out measurements in ventilation ducts and at air outlets: The testo 440 air velocity and IAQ measuring instrument, the vane probe (Ø 100 mm) with Bluetooth&reg; including temperature sensor and the vane probe (Ø 16 mm) are all safely stowed away in the case. So you can get down to work straight away!

Carry 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&reg; 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: 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, two vane probe heads (Ø 100 mm and Ø 16 mm) and a humidity/temperature probe head – all three can be attached to the universal Bluetooth&reg; handle supplied. To make measurements more convenient, both vane probe heads can be combined with the telescope included in the kit. The equipment can be transported safely and conveniently in the robust case.

Convenient measurements in ventilation ducts and at ceiling outlets: the telescope can be extended up to 1 m in length, it features easy-to-read scaling and is supplied with a 90&deg; angle. Use the handle adapter to plug the telescope onto air velocity probes with a universal Bluetooth or cable handle. 
 
Note: Please note that you need the handle adapter (order number 0554 2160) to use the telescope in conjunction with the universal handle. 
&nbsp;

The extendable telescope with easy-to-read scaling makes it easier to carry out measurements in ventilation ducts. Thanks to the supplied 90&deg; angle, you can even carry out convenient measurements at ceiling outlets. Use the handle adapter to attach the telescope to air velocity probes with a universal handle with Bluetooth&reg; or cable.
