RadonAway 50017 Easy Read Manometer, Blue

Bought this like everyone else, to monitor a radon vent system. This "gauge" does that very well and simply! My only issues is that mine came low on fluid (about 1/2-3/4" below 0), plenty if you just want it to show if they system is working but not enough to really measure. So I ended up buying a Motion Pro 08-0581 carb manometer refill kit which looks to have the same fluid! Now it is filled properly and I can monitor the actual level. 4 stars for low fluid. I didn't contact the seller about it, in hind sight might have gotten the fluid for free? But wanted to install ASAP and didn't want to wait.

Works good. Gives a constant reading of what amount of negative pressure your fan unit is producing. If you have a fan located in an area where it's hard to hear, I highly recommend you use this meter. You could see in an instant that you have a good negative air pressure condition. I have my fan located in the basement and can hear it when walking in to the mechanical room, knowing that my unit is on and functioning. I chose to use one of these anyway so I could monitor the job that the fan unit was doing. Some reviews on the fan unit stated a number of years on the fan running saw less effectiveness on it's performance. If the fan is failing this will show that there is less negative air pressure in my contained system. It installs easily and nothing much of anything to break down or fail.

My manometer story.This a great tool, quality built and reasonably priced. I'm using mine as a troubleshooting tool for vacuum operated pressure switches.I have created an inexpensive way to test your furnace pressure switches to determine, fairly precisely, at what pressure they open and close!Get an Ortho "Dial N Spray" (or similar sprayer) remove the siphon tube from the port located on the underside of the screw-on nozzle/bottle lid and insert your own vacuum tube onto the port on the bottom of the lid. Hook that tubing to the middle of a "tee" and from the tee connect two other hoses, one to the manometer and one to the pressure switch.Then hook a multimeter up to the pressure switch contacts and set the meter to its lowest resistance/continuity setting. (Hopefully, a setting with a continuity buzzer so you don't have to watch the meter itself, that way you can concentrate better on reading the manometer scale to achieve better accuracy in determining when the switch contacts make or break. Make sure you test your pressure switches in the vertical orientation.(The way they are mounted in the furnace.) It makes a difference.Hook a garden hose up to the sprayer head and select the spray setting of your choice. (I have my sprayer set at the 8 ounce setting. I don't know if the lower settings would be better?) Now VERY CAREFULLY begin to open your faucet. (Too much water flow will cause too much vacuum and it will suck out all of the fluid in the manometer!) Paying MUCH ATTENTION, SLOWLY increase water flow until you see the fluid begin to rise in the manometer. It does not take much water flow to start developing vacuum and it only requires minute adjustments to raise or lower the fluid levels in the manometer so be very careful. My stationary tubs have the lever style faucet handles and I think they are the best kind because you can tap them gently with your finger to precisely adjust the water pressure. I don't think round faucet handles, that you turn, would be able to provide the accuracy of adjustment needed compared to the lever style ones.As you slowly raise the column of fluid in the manometer you will eventually hear the buzzer sound from the multimeter. At that precise moment note the position of the fluid column on the scale and that is the pressure, in "Inches of water column", at which the contacts close inside the pressure switch. In a reverse fashion decrease the level of fluid in the manometer, by slowly decreasing water flow, until you stop hearing the multimeter buzzer at which point noting the pressure at which the pressure switch contacts open.This test can be very helpful in determining how well your pressure switches are operating.

Replace your manometer if 10 years old or older. Mine was showing only an inch if water column vacuum but looked half empty compared to new unit. Turns out fluid evaporated, new unit Shows 2.8 inch water column under same conditions. Why did I care? Because I was ready to replace my fan or start resealing pipe looking for leaks thinking I was Loosing suction and the system needed repair

This is a stone simple differential pressure gauge. No power supply, no batteries - just connect and read.I'm using it to monitor the pressure drop across the air filter in our HVAC system. We run the fan 24/7 even with air conditioning off - this keeps down the pet dander and allergens in the house. But this continual operation loads up the filter.Installation was quick and easy, but did require a trip to the hardware store to buy vinyl tubing. Drilled two holes in the air handler (one on each side of the filter) and ran the tubing to the gauge location. Didn't need sealant on either end but this depends on the tubing you get - I got lucky. Done deal.

Great little package! Not only do you get the meter but also all the radon mitigation stickers I was not sure how I was going to get my hands on. NO instructions so drill a few test holes in some spare pvc. Also, be sure to remove the rubber corks from the meter tube so it can meter vacuum on your system.

I've installed this on a radon remediation system in a crawlspace. They can be tricky to install and must be followed closely per the instructions. However, they seem accurate and reliable. Liquid will freeze though, so it must be in a climate controlled or insulated environment.

It works as described and for what it costs, it does the job. It can't affirm its accuracy since I have nothing to compare it with. I am relying on RadonAways specifications. It does let you know that the fan is working.

Just as described. It came quickly and works well. It comes with good instructions and stickers to place on the various elements of the radon removal system.

Thanks

No es un medidor de radón, solo es un tubo de plástico con líquido dentroque no sirve para nada. ¡ATENCIÓN!!

Appareil intact, bien fonctionnelle, services amazone très appréciés et rapide , Merci Émile

Great stuff. Works well
