A small, very well-made Geiger Miller counter. Possibility to measure the dose received. Robust aluminum housing, nice display. Possibility of measuring with the display dimmed, saving battery. It's sensitive, I tested it while flying an airplane, pointed to elevated radiation coming from space.
Tök jól működik. Hamar megérkezett. Angol/kínai leírással, feltöltött állapotban, töltőkábellel együtt érkezett. A terméknek jók a szolgáltatásai.
Unfortunately extremely inaccurate! The device on the left shows that it is also better.
Unit works quite well!
It arrived relatively fast. The package was harmed, but it was exceptionaly strong, so the product inside was in perfect condition. In my home I found nothing that radiate anything, now I hope that it is not just because the gauge doesent sense it. Now I'm trying to find it out and see something with which it can be calibrated.
Normally
nice unit, clearly visible display but i am not able to verify accuracy. So far happy with it
The detector's doing what it's supposed to
O.K.
seems to work, but very slow response, probably due to averaging. when placed on top of a source it takes about 20 second to respond. ok for long term exposure I suppose.
