Dive Compressed Air Testing

As a PADI preferred partner, Trace Analytics has had the honor to stand behind an organization committed to diver safety, while serving divers and dive shop owners with their custom compressed air testing needs.

Compressed Air Testing: Sport & Commercial Dive

At Trace Analytics, LLC, we have been ISO 17025 and A2LA accredited since 1989. As the leader in compressed breathing air testing and analyses, we take the health and safety of your dive customers and employees seriously. Test results are fast, and if your sample is not in compliance, we’ll call you right away! We also provide a free retest if taken within 30 days of the initial failure.

The AirCheck✓™ Kit makes compliance with your required specification simple and inexpensive. Take an air sample in about 10 minutes and return a four-ounce vial inside a pre-addressed box we provide. No heavy, bulky containers to return, and no hassle. Then we’ll deliver a fast, accurate AirCheck✓™ Report within 1-3 working days of receipt at our lab.

K902 Breathing  Air Kit

The AirCheck Kit™ K902 is designed for use with compressed breathing air specifications requiring a dry dew point, such as NFPA 1989, OSHA 1910.134 (Cylinder or SCBA), CGA Grade D (0), and CGA Grade L. Other specifications are available at an additional cost. This kit is typically used by fire service, industrial fire brigades, some dive facilities who use high pressure breathing air to fill SCBAs or any compressor with a desiccant dryer. Test from the compressor or cascade. Watch our online sampling video for Breathing Air Testing.
