Testo 420 anemometer is a professional measuring instrument that measures air velocity, volume, absolute pressure, temperature and relative humidity.
Volume flow hood Testo 420:
- Measures flow rate, volume, absolute pressure, temperature and relative humidity
- Includes an automatic zeroing function to ensure accuracy
- When used with a hood, it can take measurements in larger air inlets and outlets (610 x 610 mm) in air conditioning rooms
- Can also be used without hood
- Used with Pito tube and connecting hoses (sold separately) – measures pressure, flow rate and volume in the duct
