Dwyer6806202 2000-00 Magnehelic Differential Pressure Gauge, 2000: 0-0.25" WC

Very accurate, excellent price, at about $40 new open box.

The media could not be loaded. Unusable without the overpressure plug that must come in the back. I'm giving it 3 stars because it only cost me $ 23.66 already with taxes and it looks almost like new. It only came with two bronze 1/8 hose adapters and nothing else. I know I bought a special cheap offer but I can't understand why that simple plastic plug was not included because that makes it useless.

Works like it is suppose to. Use it to adjust air settings on the pellet stove.

Gauge comes with none of the listed accessories, just a gauge tossed in a box. These have to be mounted vertically to prevent the diaphragm from sagging, but without the factory hardware which should be included, this is not easy to accomplish. First and last Dwyer product I'll buy. Secured with gaffer tape until i replace it with something better from a better company.

This is the second I purchased. This unit has lower range needed to fit my needs. I use this to determine filter changes on my HVAC. Once the pressure increases by say 15 to 20 percent I change the filter. This allows me to keep the static pressure below 0.60 IWC specified in the installation of my air handler.

Perfect for my use

The description states it comes with the brass fitting adapters that screw into the gauge that you can connect the hoses to, they did not come with mine.

This purchase does not include the 1/8 female NPT connections and plugs. Stay away from this purchase if you need these accessories.

Très bien

Did not get everything that’s suppose to be included from the discription of the product
