Product Description

ATTENTION: As of August 1st, 2013, Quarta-Rad upgraded RADEX 1503 to RADEX 1503 Plus. Upgraded firmware, additional features, and cost the same as RADEX 1503. Don't be fooled by online vendors selling old and unsupported RADEX 1503 model as new. When you buy RADEX 1503 online, make sure it is RADEX 1503 Plus (Radex 1503+)

Now there is a better, stronger and more advanced version of our best-selling workhorse – the RD1503.

Ever since the introduction of the original RD1503, customers have been asking for additional functions and requested certain improvements on the existing design. We have listened and incorporated many new capabilities into RD1503+:


New and Improved Features of RADEX RD1503+

+ Graduated change of a threshold signal in the range from 0.10 to 0.90 µSv/h with an 0.10 µSv/h interval (available in individual settings).

+ Value of the background dose rate is saved even when the device is turned off.

+ Now displays the difference of the dose rate between the averaged and background values.

+ Includes vibration signal and audio alarm (both adjustable).

+ Added animation of the pressed command button (the icon of the button starts blinking on the display).

This new device allows a quick and easy way to check radiation background of top soil, non-edibles and interior premises.
The quality of indication of any dosimeter depends primarily on the built-in detector of ionizing radiation. RADEX RD1503+ contains a low-voltage SBM20-1 type Geiger-Muller counter of beta- and gamma-radiation which is found used in professional dosimetric equipment.
An expert scientific tool that’s made for an average Joe.

Quick, Simple, and now better than ever!

    I bought this 2 years ago to add to my "preparedness" items, tested it and then stored it away for safe keeping. When NK started making a fuss with USA after the 2016 election I got out the detector, turned it on and left it on all the time. This led to my having to replace the batteries frequently (not rechargeable) which is my first "con" of this unit. The second "con" would be the difficulty getting the battery cover off and back on. After several sets of batteries this year I finally discovered the worst "con" of this unit....it's very fragile (understand that the censor is made of glass inside the unit) and because of the difficulties changing the battery I ended up dropping the unit from about 3 feet (from my lap on the couch) at which point the unit no longer worked. I turned it on and it would register no background radiation whatsoever.If I hadn't broken this one I would not have known the difference between it and what I bought as a replacement (GMC-300E).So, when it worked it was "ok" but its design flaws set me up for failure in dropping it.Additionally, the things the Radex does NOT do that the GMC does: has an included rechargeable battery that can be charged via the usb port with a standard usb charging brick or the PC, can be attached to my PC to download the detection history, is a "dosimeter", counts in CPM as well as sV and mR, has a wrist strap to hold on to if by chance you opt to use a non-rechargeable battery and need to replace that battery, has an LED indicator that flashes for each detection as well as an audible "click" like a standard Geiger Counter that can be turned off, has an analog audio port for headphones for private listening of the "click" and ....is 30% cheaper!Edit: Having been accused of providing a fake review in the comments, I felt it appropriate to verify my claims and attach a picture to assert that the sensor IS made of glass (inside a metal sleeve) and attest that I can hear the little pieces of glass rattling around inside. Buyer beware. I'd give this product negative 5 stars if I could.

    Also kaum gekauft, gleich mal alles untersucht. Nix strahlt, die Champignons nicht, die Münzsammlung nicht, die Wohnung nicht ;)
    Also habe ich das Gerät mit in die Röntgenpraxis genommen. Da ging es aber los mit einem hohen und wie bei einem Feuermelder schrillem Ton. Ich und alle im Wartezimmer sind vor Schreck fast vom Stuhl gefallen.
    Also er funktioniert ausgezeichnet. Schade fand ich nur, dass man nicht von Micro- auf Millisievert umstellen kann.
    ——-Nachtrag——-
    Ich nutze das Gerät jetzt seit mehreren Jahren und habe es überall und bei jedem Urlaub dabei. Bislang verrichtet es seinen Dienst zuverlässig.
    Gekauft habe ich das Gerät ursprünglich, da ich ein preiswertes Einsteigergerät suchte um ein Gefühl für das Thema und Radioaktivität zu bekommen. Ich mache auch Fotos bei Flügen, wie bei einem Inlandsflug in Deutschland (Foto anbei).
    Bei Röntgenuntersuchungen nehme ich es nicht mehr mit, die Dosis ist für das Gerät zu hoch. Spannend wird es wieder zu messen, wie die Strahlung im Körper über die Tage zurück geht.
    Ich habe die Kritiken anderer Käufer gelesen und kann sie nachvollziehen.
    Wie immer ist es die Frage, wofür möchte ich das Gerät nutzen?
    Ich brauche unabhängig von Regierungs-Länder- und Behördenangaben ein Gerät, was mir echte Fakten liefern kann.
    Für mich reicht es zu wissen, dass wenn das Gerät anfängt Alarm zu schlagen, dass ich dann das Weite suchen sollte :)
    Wer sich ausgiebig mit Radioaktivität beschäftigt und höhere Werte messen möchte, der sollte auf ein anderes Gerät ausweichen.
