Another Cheap Nuclear Radiation Tester | Voltlog #423

Welcome to a new video, today we’ll be taking a look at yet another cheap radiation detector and it’s going to be similar to the one reviewed in Voltlog 416, except it’s cheaper. It’s also not as big physically and it’s not a multifunction tester, this one just measures radiation but let’s start with our basics, this is the packaging it comes in, inside the box you will find this hard shell carry case which is a nice addition when compared to the previous model we reviewed and btw this one doesn’t really have any branding or a particular model mentioned, it’s just a generic radiation tester but because of that I would image that it’s likely you will find this sold under different names, brands or even shapes.

Inside the case the meter sits nicely in this cutout and you get a short USB-C charging cable, a hand strap and a short user manual. Like mentioned this is smaller physically which could be a nice advantage, but also comes with a smaller screen. We have a couple of rubber bands on the sides and a metal clip on the back, with the charging port located on the bottom. Plastic feels soft & decent, matte black, I quite like that.

On paper at least this seems to have better sensitivity when compared to the previous model I reviewed but realistically given the size and cost of the unit, I think it must be using a similar miniaturized geiger muller tube which is not the most sensitive tube for this type of application but it does have the size and cost advantage. We’ll be able to see more about this topic in the teardown but first let’s turn on the unit.

The screen on this unit feels a bit small at just 2 inches. I mean , in this reading mode, I can clearly see the readings which are using this nice and big 7-segment font, but the small text on the blue ribbons, that seems a bit small to easily read. On the plus side, brightness seems good, easily visible even under my bright video shooting lights. The problem is more apparent when you switch to the menu system which feels really crowded, they went with this thumbnail arrangement, the icons feel small, the text feels small. I would have probably preferred just a simple list menu for this with bigger text.

In terms of functionality you get the standard measure & display screen but you also have the options of setting up alarm thresholds and the meter can continue monitoring with the screen off for up to 20 days of battery life and it will trigger an alarm once the threshold is exceeded. It lets you configure the screen off timeout as well as the auto power off timeout which is nice and It can also do data logging although I have not seen any mention of the available memory. A couple of other settings for things like language or screen brightness are also available from the menu system.

Getting a Geiger Counter Radiation Detector Might Be Useful | Voltlog #416

So I looked around for a portable Geiger counter that might give some indication or warning if the radiation levels start to increase. There are a few models available online, some which are for professional use but ofcourse you would expect those to be very expensive, so I was looking for something on the affordable side of things.

This model popped up in my searches, is the JD-3001 multifunctional Geiger counter and this can monitor gamma beta as well as electric and magnetic fields all in the same unit. I’m gonna put the specs of the unit on screen while I mention that it was offered for free by banggood.com for the purpose of this review and right now there is a high demand for these, but it shows in stock on banggood.com, the price is discounted and on top of that if you look in the description of the video you will find a coupon code that will provide you with an additional discount for this product.

Not sure how relevant it is but the unit also includes a temperature + humidity sensor which is located in this small extremity. When compared to other units available on the market this one seemed more interesting because it had some nice features like built-in lithium battery, rechargeable via USB Type-C port. It can do data logging on its internal memory and then you can access and download the logs through the USB port and probably the nicest feature is this big crisp color LCD display.
