With Lawrence Factors patented do-it-yourself air testing kit you can test your compressed air source as needed. The process is as easy as filling a Scuba or SCBA cylinder and takes about 10 minutes to perform and fill in the paperwork. The sample is then shipped back to X-Zam labs in Miami Lakes, Florida which is backed by ISO-17025 accreditation. After receipt and analysis at the lab, a certificate is emailed to you referenced against the chosen testing standard. Click here for more information Air Sampling Process.
