Stainless steel Pitot tube (1000 mm, &Oslash; 7 mm) designed for accurate measurement of flow velocity in high-speed and contaminated airflows. Ideal for use with compatible Testo measuring instruments or probes.

Stainless steel Pitot tube (350 mm) designed for accurate measurement of flow velocity in high-speed or contaminated airflow environments. Compatible with Testo measuring instruments.

Robust stainless steel Pitot tube (500 mm length, 7 mm &Oslash;) for accurate flow velocity measurements in high-speed or contaminated air streams. Ideal for use with compatible Testo measuring instruments.

Robust Pitot tube for measuring flow velocity: the Pitot tube provides the optimum conditions, especially for higher flow velocities and for heavily contaminated flow. The 750 mm long Pitot tube has integrated temperature measurement and a connection hose with a maximum load capacity of up to 700 hPa (mbar).

In the event of dust-laden flow in ventilation ducts or process air and higher flow velocities, we recommend using a Pitot tube.

Make sure you get the testo 420 volume flow hood for larger ceiling outlets and at the same time enjoy multiple maintenance benefits on HVAC systems. Because the flow hood with the removable measuring instrument is not only exceptionally light, it also guarantees accurate volume flow calculations at swirl outlets

Use the testo 420 differential pressure measuring instrument to carry out simple, efficient tests on filters. You can also use the measuring instrument in conjunction with a Pitot tube to measure flow velocity and volume flow really easily in ventilation ducts.

Precise, reliable measurement of all air velocity and IAQ parameters with the testo 440 dP: the multifunction measuring instrument features an integrated differential pressure sensor and intuitive operation with clearly structured measurement menus. Adjusting air conditioning and ventilation systems, monitoring air quality or carrying out comfort level measurements &ndash; thanks to versatile options for combining with high-quality, digital probes, you are ideally equipped to carry out your measuring task (please order probes separately).

The testo 440 delta P Air Flow ComboKit 1 with Bluetooth&reg; provides a complete, wireless solution for measuring air velocity, differential pressure, humidity, and temperature in ventilation ducts and at air outlets. It includes the testo 440 IAQ measuring instrument, a 100 mm vane probe, a hot wire probe (&Oslash; 9 mm), and a differential pressure sensor, all stored in a convenient, rugged carrying case.

The testo 440 delta P Air Flow ComboKit 2 with Bluetooth&reg; is a versatile, all-in-one solution for measuring air velocity, differential pressure, humidity, and temperature in ventilation ducts, air outlets, and workrooms. The kit includes the testo 440 IAQ measuring instrument, two vane probe heads (&Oslash; 100 mm and &Oslash; 16 mm), a humidity/temperature probe head, and a differential pressure sensor. All components are stored in a durable carrying case for easy transport.

You can keep a close eye on indoor air quality with the testo 445 climate measuring instrument: the allrounder can measure up to 6 parameters (with the appropriate probe), which can help you make a professional assessment of indoor air quality. The climate measuring instrument therefore supports you in adjusting and checking ventilation and air conditioning systems.

The testo 526-2 high-precision differential pressure measuring instrument is ideally suited for checking pressure in sensitive industrial processes, thanks to a measuring accuracy of &plusmn; 0.05% of final value. Two additional pressure and temperature probes can also be attached.

The testo 400 is the ultimate tool for professionals in indoor air quality (IAQ) measurement. It offers a wide range of features including intuitive measurement programs, high-precision sensors, and the ability to connect a variety of probes. It&rsquo;s the ideal instrument for measuring, analysing, and documenting all IAQ and comfort parameters, providing full compliance with standards.

Ideal kit for IAQ professionals, with a focus on indoor air quality and comfort level. You will receive the testo 400 universal IAQ measuring instrument with intuitive measurement menus, one CO₂ probe (with Bluetooth&reg; handle), one turbulence probe and one globe thermometer &Oslash; 150 mm (both with fixed cable). Use the measuring tripod to ensure standard-compliant positioning of the probes. In combination with the IAQ data logger, which is available to order separately, long-term measurements up to 2 weeks can be recorded, even without the IAQ measuring instrument.
