This item replaces: EM151
Direct Replacement:
Easy-to-Use Differential Manometer for Draft, Gas Supply, Manifold, or Burner Pressures
Description
–
The EM152 differential pressure manometer replaces the EM151 with additional
features and the same professional accuracy. Even though the EM152 offers
differential pressure it is not a competitive option to the EM201B’s higher accuracy.
Professional enhancements
The EM152 offers the same features as the previous model with nice upgrades besides the dual input differential. The range was increased to -60 to +60 inH20 (from -20 to +20 in H20). Users now have 11 scales to choose from, over the 3 scales in the previous model. The EM152 also features an easy-to-read high contrast backlit display, MIN/MAX, and a bulit in magnet for hands-free work.
The boot was replaced with over molding and a secure grip handle that fits better in the hand and offers additional protection and reliability in tough workspaces.

Didn't have one, needed one, it worked, now what
I'm not a pro but needed to measure gas pressure for peace of mind while doing my install, so I bought this.
I used it, once. Glad I bought it. But I'd be surprised to ever use it again, since I'm not a pro. Anyone want mine? haha

Looking for a different one
The power button too sensitive, it would come on while in tool bag and the battery was dead whenever I needed to use it. I resorted to removing the battery after use. Later it wouldn't stay on and had to hold the power button in to get the readings.

Best value out here. EZ to use for combi boiler setup
Using for HVAC testing of filters efficiency, gas valve pressure in/out, and DP testing. Better than analog style meter due to digital zeroing. Value priced tool.

Meh
My mentor had one and its the one I learned with. The one that I bought does not have as strong of a magnet and needs to be zeroed out every single time I use it. That is sooo convenient as I use it up to seven times a day, lol.

Manometer works correctly out of the box
I had not used one in years; but needed to test high & low burner gas pressures on my new Rannai wall heater. Our cabin is at 7000ft altitude.
Supply house shipped & delivered quickly. Heater works correctly.
