Mūsų radiometras pagamintas iš stiklinės lemputės, iš kurios pašalinta daug oro. Lemputės viduje, ant mažos trinties veleno, yra rotorius su 4 mentelėmis. Kiekviena mentelė turi vieną pajuodusią ir vieną pasidabruotą pusę; vienoje juodoje mentėje yra baltas taškas, kad būtų galima lengvai skaičiuoti apsisukimus. Veikiant saulės šviesai arba dirbtinei šviesai, mentelės sukasi be jokios akivaizdžios varomosios jėgos. Šis efektas atsiranda dėl skirtingo juodų ir sidabruotų mentelių šildymo.

Kilmės šalis: JAV. Pakuotės kiekis: 1. Produkto tipas: Laboratorinis tiekimas. Pakuotės matmenys: 16,51 cm (ilgis) x 8,636 cm (plotis) x 8,636 cm (aukštis).

Great for learning!
Works like a charm. Will absolutly do the job for the price. Nobody needs a top of the line Radiometer lol. Runs pretty damn fast on a sunny day.

Radiometers are FUN!
The quality is disappointing to me. The vanes appear to not spin as easily as the higher quality radiometers, so the performance is comprised. Other than that, it looks nice. I've owned several over my lifetime but this one just doesn't make the grade in my opinion.

Cheap
The radiometer doesnt work. Ive placed it in multiple well lit environments and the blades dont spin.

Old and worn
The product was old. The panes bent and had heat burn holes. The item did not turn with a flashlight.

Didn't Work
Didn't work, even in bright sunlight. The metal pole appears to be bent so I think the spinner is contacting it. Even a little bit of friction will prevent motion. We already have another radiometer and that one cost less yet works fine.

Waste of money spend a little more for something that works
2 units, first one the inside parts were broken on arrival, the second just didn’t work. Waste of money

You get what you pay for!
Poor quality and it didn't even work. The vanes were crooked and bent. Buy a better quality radiometer at a fair price and not at the bottom of the market like this one.

Low quality control. One good, One wobbly.
Internals a bit inconsistent. They are fragile. I bought two. One was okay other wobbles due to poor quality control. They both work.

Very Dissatisfied
The device did not work. It is very frustrating to receive products via the mail and then they do not work. It is more trouble to send them back. Fortunately the product was only a waste of $20.

Don't waste your money.
Absolute garbage. Had to return the first one I received! And the replacement arrived intact, and broke after 3 days. Useless, look elsewhere bill nye!

There is no real quality; and would not even turn/spin in the daytime sunlight, so I do not know what to say. I did return it.
