Features
- Work efficiently under 3.3V and 5V
- Support with both Arduino and Rasberry Pi
- Compact size for easy deployment
- Probe replaceable
Warnings and Operation Cautions
- When measuring the electrode, the test part of the electrode (including platinum wire and reference junction) must be submerged at the same time.
- The electrode standard solution-quinone hydroquinone saturated solution, the storage time is 48h. (Attachment: Preparation of quinone hydroquinone saturated solution: add excess quinone hydroquinone to the pH 4.00 buffer to make it saturated).
- If the platinum wire of the electrode is stained with grease, it can be scrubbed with absorbent cotton and acetone or alcohol. And if it is dipped by insoluble inorganic substance, 30-50% hydrochloric acid works as well. Besides, it can also be cleaned by senior toilet paper once every day.

Works Great, A Lot of Elbow Greese, but Worth the Effort!
Transformed our motorhome exterior . It looks new, brighter, and no haze! It helped to watch the instruction videos on YouTube.

Wow just wow. It works great.
I have a 2017 vengeance and it has had a bit of sun even though it stays in a building when not used. It was getting a bit of fading even though I polish it each year. I wanted to try something and this was what I settled one after looking. Yes it is a bit of work on a 43’ fifth wheel. I ordered 2 kits but after a week of working on it after work we went camping and where next to a week old fifth wheel and he asked what I used to make it look better than his. It has a mirror finish on it now. After 6 months it still looks great and it’s durable and ease of use. What an effective product

Great product for rv
This is an excellent product. The front of our camper was very faded from the sun even though we keep it under a cover. After four coats, it looks like a different RV. We are going to do the entire camper. The difference is amazing. You will be so happy with the results. We would give it a 10 if possible.

Amazing fiberglass restoration.
So easy to use and fabulous results. A few years back I had tried Maguires products to restore the shine on a 5th wheel. That was so labor intensive and the results were struggled to achieve faded quickly. I hesitated to Poli Glow due to the cost and our prior attempts lackluster results. I was able to get the restoration kit at a discount on Black Friday through the stores website and tackled the camper with the temps between 60-90 as instructed. I bought 2 of those kits just to find out that due to the climate and UV exposure the number of coats I would need for the Poli Glow was going to exceed the amount I had on hand through the 2 restoration kits. So I had to scramble to buy another bottle of Poli Glow. Applying this product is just time consuming and not difficult. Make sure to properly prepare the surface before using poliglow. The whole system turn a badly oxidized camper into a shiny finish. I am truly shocked. Hopeful the results will last a while.
5th wheel camper 40 foot long.
I have used 3 poliglow bottles (12 coats), 1 bottle poli ox, 1.5 bottles of Poli wash (of course, not in that order). I potentially need 1 more bottle of Poli Glow to finish nose cone/basement area (basement area is still in good condition so may not do this area if I can get the nose cone with the remainder of the Poli glow I have.)

Worth the time and effort.
After proper surface prep and 6 applications, my badly sun damaged RV shined like new, with many compliments. However, after a few months under the cover, the fiberglass surfaces that were in contact with the occasionally wet cover in the Florida sun discolored badly, and will have to be wet sanded and the coating re-applied. Also, the polish does not hold up well where boat fenders rub against the coating, and it wears away in cockpit areas that are heavy hand traffic, like hatchways and around handrails.
Overall a decent product, I will probably re-apply in a couple seasons.
