VISLONE Ozone Detector, O3 Air Quality Monitor, Gas Tester Meter Home Indoor Intelligent Sensor Pollution Monitor

The media could not be loaded. Since I got infected with Covid 19, I had to isolate myself in my home office. After my isolation period, I needed to sanitize the room I was in, and an ozone generator is perfect for this application. The drawback is that to sanitize the space, I had to set the ozone generator to output more ozone than usual to increase its efficacy in eradicating viruses.Which is why I bought this tool. It is a must to monitor ozone levels outside of the area being treated. You do not want your family or pets breathing in this gas as it is an irritant and may cause health issues. Not only that, after treatment, you need to make sure all ozone gas decomposes back into oxygen before you repopulate the area being treated. This meter samples readings fast! And it is very sensitive to dynamically changing levels of ozone.You can see in my video, right when I power on the ozone generator, the meter peaks to max reading. As I walk out of the room into an open area, you can see the meter update me ozone levels almost in real time! Amazing product, amazing build quality, and fits my requirement perfectly! 100% recommend!

I bought two of these products with the intention of verifying their accuracy. I set them up side by side, following the same instructions and properly burned them in. However, the readings I obtained were extremely inconsistent. To further investigate, I purchased two IC2 Gravity ozone meter readers, and surprisingly, they yielded varying results on each device, which also differed from the readings provided by Vislone. In an attempt to cross-validate, I even acquired paper test strips, but disappointingly, they too gave different results. The scaling on the logging graph is not correct making that feature useless for logging the inaccurate ozone results.

Works

When I first checked this one out I saw that there was misspelled words and thought that maybe it was a little less expensive due to a spelling error causing it to be an irregular stock item. See the added photo and the misspelled word that should be spelled "Moderate", not "Monderate".Everybody has jumped on the "air quality" band wagon in order to make a quick big buck and is why these kind of things are so ridiculously expensive. But I just needed a simple O3 meter for when I am generating ozone to make sure we are in the green. I don't know if this thing is even accurate at all. I was smelling the ozone quite heavily and this did not even move above 0.025 ppm after an initial reading of 0.017. In concern I moved it closer to the bottom crack of the door opening and it eventually flew way up and alarmed at 1.0+. I never saw the level climbing, it just seemed to go from one extreme to the next.When I initially unboxed it, it seemed rather lightweight and not very "quality" feeling. It didn't turn on so I found a charger and plugged the USB cord into it. It has a cord, but not a charger. I had to ask myself... Is it charging? There was no indication that it was. No light or anything indicating a charge. After a few moments I was able to turn it on. The screen showed it was charging with the battery indicator moving. So I was like... well that's dumb, turning it on is the only way to know it is charging. I gave it about an hour and checked the charge indicator which was still doing its marquis thing and not showing there was any charge being held. So I unplugged it and it showed it was at a full charge. So you never know when it gets done charging. The charge didn't last but a couple of hours of continuous use before I felt it should go on the charger again. At least it was indicating that it was losing a charge.When I was done and felt the O3 was at a safe level, I turned it off and set it on a counter in a dark room when I noticed a red light glowing inside the charging port. Then I realized, no wonder why the battery was completely dead when I got it. This light drains the battery while it is off. Therefore, there isn't any storing this thing. It will be dead when you need to use it after storing it. See the added photo.So, in conclusion, I believe this is not a "irregular" item, but is truly an Asian built, questionable item that is definitely not worth the price, as I cannot be assured I haven't been exposed to high levels of O3 because I cannot be sure it was showing me accurate readings. There are way too many quirks about this item, so I cannot trust it to keep me, pets or any Family members safe.I feel I should return as it really isn't doing for me what the intention of it was for. It's supposed to make me feel confident that I am not poisoning the environment that I am residing in. I am going to have to make a decision and I am probably going to get rid of it because I would rather spend a lot more on something I know is working properly and keeping my living environment safe.

The display is easy to read. The unit itself is easy to handle, light weight and compact.I've used it indoors and outdoors, and the readings basically stay the same. I was surprised, because we're having ozone warning in the Phoenix area, and still reading well within the limit. Not sure of accuracy.
