Dive Industry

If you are SCUBA diving for fun or it’s your profession, the last thing you need to worry about is your compressed air and pure gas quality and how safe it is. TRI Air Testing can help with compressed air and pure gas testing for SCUBA Grade E, PADI dive air, oxygen compatible and more! 

TRI Air Testing compressed air and pure gas sampling equipment was designed to capture a non-pressurized sample of compressed breathing air for analysis by TRI Air Testing, an ISO 17025:2017 accredited laboratory.

TRI Air Testing can answer any questions on compressed breathing air and pure gas testing for SCUBA diving and surface supplied air. We can also assist with setting up a custom compressed air and pure gas quality program for any company. Here are the dive categories TRI Air Testing specializes in…

  • Recreational or Sport Diving. For any retail dive shop, TRI Air Testing is knowledgeable in all standard testing programs and procedures across the dive industry. TRI Air Testing can test SCUBA compressed breathing air and pure gas to CGA Grade E, PADI, ANDI or Grade E Oxygen Compatible.   

  • Commercial Diving. Commercial divers build underwater structures such as oil platforms. They also perform services such as underwater maintenance, surveys, map creation, and salvage operations. TRI Air Testing can test the air and pure gas quality of all compressed breathing air and pure gas to the OSHA or ADC Commercial Diving Standard. 

  • Investigative Diving. Police Departments have specialized dive teams trained to recover evidence and perform forensics for legal cases. Some of these investigations require deep diving with high degrees of difficulty. TRI Air Testing specializes in PADI dive safety requirements to keep investigation divers safe. Visit the PADI web page for more information.

  • Military Diving. Like commercial diving, military diving is similar but also involves tactics such as underwater surveillance and military research. TRI Air Testing can test breathing air and pure gas quality to Military Dive Standards or the ADC Commercial Diving Standard. TRI Air Testing currently holds the contract for the US Navy DCAT Dive Program.
