Review on 🌬️ BIAOLING Accurate Formaldehyde Multifunctional Recording: Say Goodbye to Indoor Air Pollutants! by Jerry Frey

I bought this for two reasons: 1. To find an exhaust leak in a classic VW Beetle. I thought it was a leak from one side of the heat boxes but turns out the exhaust leak is being sucked into the air intake. Without this counter it would be impossible to track.2. To determine if my home office was adequately ventilated (which turned out not to be the case). It's easy to use. Seems accurate, but it's not a super portable device, so it's more accurate if left alone for a few minutes. CO and CO2 readings typically respond within 5-10 seconds to changing conditions, such as: B. opening a window. What would I pay more for? , in the priority list: 1. I would like a wireless application where I could set alarms with alarm levels.2. I wish it had Wi-Fi connectivity and a cloud service so I can remotely monitor the room.3. I wish the color display could show health hazard levels more easily.4. I'd like more air quality readings like radon, as well as simple temperature and humidity readings.
