well made and a good filter monitor. I heve used for years.

I bought this to set the barometric damper on my coal stoker boiler. It was very easy to install and set up. I would have had no idea how to set the barometric damper without this item.

No more guessing when the filter needs changing!
Excellent.

Works very well with the connectors provided in the box and it doesn't need the Dwyer static tip which are too big for the hose provided with the mark II. I used it on my furnace on both sides of the filter and it gives me the differential so I know when my filter needs to be replaced.
