Concerning the Helium sensor that was on display at DEMA, I saw it on display in the Dive-Rite booth. It was a Helium sensor for testing helium concentration in tanks. They claimed that it used a differential calculation on the thermal conductivity of air vs. the helium mixture. They claimed an accuracy of +/- 1%. Sounds interesting. Any thoughts??
