XYF Air Easy Read Manometer | U-Tube Air Pressure Indicator (Blue)

Easy to install. Total time: 15 mins. Provides a reliable relative indication on radon mitigation system air flow. My system ices up at the roof discharge when the temps get below about -3F (North Dakota). I am planning to install a trace heat system this spring to avoid ice-ups. Until then, this simple device lets me know when I need to thaw out the radon chimney with my heat gun on a pole!It should also provide a reliable indicator if your radon mitigation system fan is not operating.

Easy install. Good instructions!

Works great. Easy to install. :)

This looks like a good product for our radon mitigation system. It is made of glass. I do not know how we received it without breaking as it had no packaging around it other than a plastic wrapper from the manufacturer.It did work as expected after installation.

Verily, I doth extol the virtues of this Radon manometer, for it doth present itself as an instrument of ease both in the installation thereof and in the decipherment of its readings. With great joy doth I proclaim that now, by its blessed presence, I am enabled to vigilantly oversee the status of mine radon fan. By heavenly decree, I do bestow upon it the maximum count of five stars, for no lesser appraisal would suffice to capture its excellence in full measure.Hark! The process of installing this instrument proved to be a venture most straightforward, as if guided by the very hand of Providence. No insurmountable challenges did it lay upon my humble self, for its design did cater to the simplicity craved by mortal minds. Even a neophyte in the realm of contraptions could fathom its assembly without struggle or consternation.As I laid mine eyes upon the manometer's countenance, my heart did palpitate with glee, for its markings were most legible and clear, akin to sacred scriptures etched upon vellum by scribes of yore. Its true essence was thus revealed to mine senses, and I found myself effortlessly decoding the counsel it imparted regarding the radiant radon fan. Verily, it granted me insight into the unseen currents of the air, protecting me from the invisible menace that lurks within the earth's bosom.Such was the profound impact of this instrument that I am compelled to share my adulation with fellow seekers of safety and sagacity. Henceforth, I proffer unto it the highest esteem - five stars that sparkle like celestial jewels - tokens of mine ardent devotion and approbation. May it be known far and wide that the Radon manometer is a paragon of ease, a beacon of discernment, and a guardian of lives against the lurking dangers of the unseen radon realm.

Works like it should.

Absolute necessity, easy to install, easy to read, good quality.

Order else where. This is CHEAP GARBAGE!!!
