Review on 🌱 Optimized Hydroponics Incubator for Ensuring Forensics Battery Quality by Chad Judex

This is a very simple little plug in CO2 meter. Easy to read. It immediately registers increases and decreases in CO2 concentration. Even if you just sit next to it and breathe, it captures the CO2 you exhale. I'm not a scientist so I have no idea if it's measuring correctly compared to a high end scientist machine. I'm wondering if there's any way to know how accurate it is? But it certainly gives me a relative measure of how much CO2 is rising in a room with people. Also, I don't know how to contact the manufacturer if there are problems. There doesn't seem to be a contact phone number in the package. That's definitely negative. Contact information must be CLEARLY printed on the packaging.
