To ensure full accuracy when performing measurements with the testo 420 balometer, a minimum outlet size of 335 x 335 mm must be provided. The correct measurement surface is essential for achieving a stable airflow and eliminating errors caused by turbulence. This guarantees precise results that serve as a reliable basis for the analysis and adjustment of ventilation and air conditioning systems.

The measurement hood is dedicated to the testo 420 balometer (0563 4200), which has been specifically designed for measurements on large ventilation grilles, including swirl diffusers. Its integrated flow straightener significantly reduces the influence of turbulence by converting irregular airflows into an even, uniform stream. This enables highly accurate determination of volume flow rates within the range of 80 to 3,500 m³/h, making the instrument an invaluable tool in facilities such as hospitals, office buildings, and commercial properties.

One of the major advantages of the testo 420 balometer is its ergonomics and mobility. Weighing less than 2.9 kg, it is exceptionally lightweight and convenient for everyday use. Ergonomic handles, a rotatable display, and simple keypad operation allow measurements to be carried out quickly and effortlessly. In addition, data logging and easy export to reports greatly simplify documentation. Combined with optional hoods of various sizes and a telescopic tripod, the balometer becomes a versatile tool adaptable to a wide range of measurement conditions.

The delivery scope includes a measurement hood and a practical carrying bag, which facilitates safe transport and protects accessories against damage. This ensures convenient and reliable use of the balometer in the field. Thanks to integration with the free mobile app, the user can also operate the device remotely, create reports on site, and send them via e-mail, significantly increasing efficiency. Altogether, the testo 420 with its measurement hoods forms a complete and dependable system for controlling and optimizing airflow in HVAC installations.
