GA-TekCheck Oxygen Helium Analyze

TekCheck   Oxygen/Helium Analyzer

If you are diving with helium based breathing mixtures you need to know what is in the mix. The TDL TekCheck is uniquely designed to analyze BOTH the oxygen and the helium content of the mix.

Light weight and easy to use. TekCheck has dual 3.5 digit displays -- one for Oxygen and the other for Helium.  The analysis is simultaneous and will operate on the internal rechargeable battery for 3 continuous use hours. Recharge time is 2 hours. A red LED will notify user when battery condition is low. This is a "flow through" unit in that gas will pass in-front of the sensors and display the proper oxygen and helium content. Input flow rate to be at 3 lpm or less.  No longer will trimix divers and professional trimix instructors need to "guess" at the diving mix content.
