The NEW testo 420 air capture hood for larger air inlets and outlets enables fast and precise calculation of the overall air capture on HVAC systems. It helps in frequent air capture calculations in large rooms and measurements above head height can also be carried out reliably and comfortably, thanks to its ergonomic handles and tiltable display which results in a significant loss in the overall weight of the instrument.

Features:

• Significantly light with a weight of 2.9 kg
• Precise measurement even at swirl outlets
• App integration via Bluetooth for fast and easy monitoring and reporting on site
• Removable and tiltable measuring instrument with a large display

Additional Information:

• Item Code: Testo-420

Product Details:

Testo 410-2 is designed for the measurement of air flow velocity, temperature and humidity. Testo's own patented humidity sensor guarantees reliable measurement results.
