    Formaldehyde HCHO

    I. Love this device it's the 3rd product I've tried on formaldehyde readers your product very accurate and ease to use I'm in a mobile home and we have issues that we suspect to be formaldehyde related . I also work in a hair salon and can take with me in pocket. I also would like to share this site as you have other readers of interest.

    "Easy to install, easy to set up, and easy calibration - just what I was looking for."
