The Handi+ is everything it's always been and more! Maxtec has improved the Handi O2 analyzer to better meet your needs for nitrox analysis. The simple to use, one-touch calibration button, new overmold and calibration reminder combined with the traditional 2 year warranty, auto-off and size make it the best of its class.
