New toys for me to try out and review today

All tools this time. Nitrogen analyzer for tires. Two trucks go to the dealership tomorrow , tungsten tires are 76 - 91% pure nitrogen should be 100% two on the longhorn reads 0%. Already talked to the dealer who is three houses down and he's pissed about it, checked his tires and they're 98% pure.
He borrowed my tester for a few days.
