RadonAway 50017 Easy Read Manometer, Blue

Functions as per description. works on any DP application within its DP "wc scale. Portable and easy to use.

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.

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

Works as expected. Easy to install

Monitors the Radon air handling. Confirms that the system is working. And EASY to set up!
