Hi, I am considering the DIY Pro pre-soldered but have two questions:
-
What procedures are needed to calibrate the unit? I live in a high rise apartment in which it’s not practical to do something like put the unit outside for 6 hours. I also do not currently have an air purifier and would not want to buy one before understanding what my baseline situation is.
-
One of the things I do not like about consumer sensors on the market, in addition to not being able to get access to the data, is the low transparency about specs. Specifically, accuracy, working life and drift for each sensor. For example the company Airthings says “The lifespan of the Wave Plus and it’s sensors would be similar to that of a smoke detector so it should last for many many years if kept in the recommended operating environment.” I don’t believe it particularly for VOC. (I am are the Airgradient DIY does not ship with a VOC sensor). Specificity lends credibility.
Thanks for any help & insights anyone can provide!
