This is an amazingly perfect set of gauges for HVAC use. It's purpose-built and has all the range and features you need. The only thing you need to improve this kit is: put a screw on the alligator clips for the probes (add a guide for the probes), improve the hanging system with a magnet so that a hook can be used, a second strap for it provide the second thermocouple. . Cons are not significant and I highly recommend this set.
