Review on Formaldehyde Detector Accurately Pollution Volatile by Shigg Bigbee

The detector does not detect radon as stated first in the product description. Second, the temperature alone was over 5 degrees. This gives me no confidence in the accuracy of other, more important, measured characteristics. There is a possibility of offset, so it can be useful if you have a calibrated sample to set the necessary offsets for all measured elements. If you don't have the opportunity to compare with someone you know, it probably doesn't offer any certainty.
