Saved my oven! in vacuum gauge

Our oven stopped working this fall because the ignition wouldn't turn on. I'm not a technician, but I was able to trace the problem to the condenser vacuum switch. This gauge helped me determine if the switch was good and the vacuum was too low. After making sure the condenser wasn't clogged, I found that the problem was partially blocked by furnace exhaust fumes outside our home. The clog was cleared and the condenser vacuum jumped from 0.9 to 1.7 inches of water, enough to close the vacuumโ€ฆ

Pros
  • Best suited for measuring HVAC systems. Widely used for gas measurement, calibration and troubleshooting of gas pressure systems.
Cons
  • Not sure

Broke on FIRST use. Built to fail!

In my first picture you can see where the four differential pressure sensor connectors are broken. You'll also notice two holes on the side of the sensor. (Second image.) In the GUT scenario, these two holes are screwed into the body of the clam. This will prevent the four pins from breaking. This tool is designed for removing stuck hoses from barbed fittings. Why are only four plastic clips used to prevent tool breakage? (Picture 3) Edit: In no more than 1 day I've already sent 3 messages back

Pros
  • Battery indicator and auto shut off feature
Cons
  • So far so good

Amazing accuracy for the money

I ordered a unit off eBay for $40 but it got lost in shipping somewhere so I started buying again. I stumbled across this one at Revain and it was almost half the price (and I'm pretty sure the 'guts' are identical on these budget Chinese instruments). Anyway, this one measures in about a dozen different scales/units and also does difference measurements. All I ever needed it for was static pressure in my HVAC system, so I only cared about inches of water. This particular accuracy of reading is

Pros
  • Max/Min/Avg recorder
Cons
  • Available in white only
