Yellow Jacket 78060 Complete Test Kit, 0-35" W.C

I used this gage to adjust pressure after converting a propane heater to natural gas since they use different pressures.I probably will not use this tool very often ( I am not in the HVAC trade ) and did not need a " high end " gage , so the low price was perfect.

Everyone at my Camping World uses these for their daily work.RV Service Technician (RVIA/RVDA Certification No. 105771)EDIT: works great...until it doesn't. I came to work this Friday and couldn't get a reading on this, even if I blew into it. Cause: failed diaphragm.

Good product for my HVAC program where we measure W.C of natural gas. 8" . Anything more than 10 I believe you'd want a digital meter or a U shaped one. Would use this to double check readings on a digital manometer to ensure accuracy.

Worked fine. When I opened the case I tried to remove the meter. It was almost impossible. No visible tape holding it in place so I tugged and I tugged until it broke free. There it was, a piece of industrial strength sticky tape holding it in the box. Meter is easy to read, worked fine for me.

Worked great for checking gas flow on a couple heaters that we have.

If you're buying one of these on amazon, buy 3 of them and use different shipping methods for all 3.They often come screwed up in the mail because if you drop this thing... even from a couple feet onto gravel - it's ruined and unreliable.

Awesome gauge. Buy it and put it to use. Works extremely well. Well protected and I keep it well protected as the box is in a bubble wrapped pouch. Kind of anal, but I want to keep it in excellent condition for a long time as it is a very important tool.

Very easy to use in checking RVs for gas leaks.
