1/2 PCS J305 Geiger Counter Tube for Nuclear Radiation Detector GM Tube Radiation Monitor Accessory
A part of the review has been auto-translated.
The Geiger tube was installed in a RadiationD-v1.1(CAJOE) panel and it works as expected!
The tube is fine and works well. Good price.
Good tube, high sensitivity.
Very good, high sensitivity tube.
The tubes travelled around the word for 23 days, in assistance of at least 3 carriers. It seems that the chinese millimeters are differ from other ones because the tubes are about 105 mm long instead of the 88 mm in the description and on the product page. It is not problem for me, I can use them but it may be a problem for other people. The packaging is good. There was not any damages neither on the package nor on the tubes. The tubes were tested and operate well.
I purchased 4 tubes (two pairs), one tube was not functioning properly._I contacted the dealer, but after an initial contact, despite repeated requests he never showed up again
