- icda104 (3874)- Bewertung vom Käufer.Vor über einem JahrBestätigter KaufNOT TRUE - NOT POSITIVE! Buyer was Definitely Offered a Refund!!! USPS LOST this PACKAGE; No scanned or updated tracking at all. 5 days after shipping "Over the NY Holiday", buyer complained he had not received his item. I went out of my way to appease this gentleman & when I asked that he wait a few more days that USPS might still deliver, he became demanding & pushy. After I told him I wd make sure he took No Loss, he opened a case and Stated that I Refused to refund him. TOTAL LOSS FOR ME!!!

Not inspired with the stability of MH-Z19B sensors.
1 von 1 finden das hilfreich Recently I bought several Carbon Dioxide CO2 sensors and two of them were MH-Z19B.
0-5000ppm works better than 0-2000ppm MH-Z19B sensor.
These sensors are cheap and can give you general information about CO2 level.
If you want one sensor and want to relay on this sensor only, I'd not recommend MH-Z19B,
unless you have other reliable sensors and you want to understand MH-Z19B as well.
