Checking HVAC Air Flow
I use this to check the air flow in my HVAC system to determine when air filters need to be replaced. The bluetooth connection and the app work great. (Retired HVAC geek.🙂)

Easy to use anemometer
Anemometers are used to measure air speed. Many use little propellers that spin with airflow, but if you need to measure airflow inside of an enclosed space Testo 405i is what you need. Place the Testo measurement probe thru a small hole and air speed is simple. Very easy to use and good value for the design

Equipo
Entrega puntual, equipo correcto, solo que certificado de calibración viene en idioma original y no en inglés, hay que traducir y no es factible.

Works Perfect
This works very well - exactly what I was looking for. A budget and user friendly way to spot-check our fume hoods to make sure they're still operating correctly between annual certifications.

Fragile
Worked great with the Testo app, rather convenient! Got one use out it when it fell from my stepladder, hit the floor and the bulb wires separated. No external damage. Granted, DON'T drop them, but for the price, it should be able to take a little bounce from field use. Not worth sending it back to Testo, $25 upfront for handling before it is evaluated for an obvious bulb change (Testo does not sell a field replaceable bulb). Don't bang it or drop it. or maybe just buy one that's a little more robust or has a replacement bulb/wand for those times you do.
