Review on Accurate Temperature Humidity Detector 0 9999Ppm by Jose Schweigert

Revainrating 5 out of 5

Insufficient information

I have purchased this product and have read the information leaflet. However, there is nowhere in the magazine what a good CO2 value is! I don't know what to set the alarm for. The back of the brochure says "call our dedicated technical support" but unfortunately there is no contact information. Please help. I finally got an answer to my CO2 question, so I'm changing my rating to 5 stars. I share these numbers. Hope that helps! The relevant standard CO2 levels you participate in are as follows: 1. 350~450ppm: as for normal outdoor environments. 2. 350~1000ppm: fresh air and steady breathing. 3. 1000~2000ppm: cloudy and sleepy feeling. 4. 2000~5000ppm: headache, lethargy, lethargy, poor concentration, palpitations, mild nausea.5. Above 5,000 ppm: Can cause severe hypoxia resulting in permanent brain damage, coma, and even death.

Pros
