Radex RD1503 Dosimeter (Outdoor-Version), hochgenauer Geigerzähler, für Kernradiation

The cover of the battery compartment should be more fixed.

Viel zu teuer. Aber gut in der Qualität und Funktion. Sehr einfach in dem Umgehen. Aus meiner Sicht es ist die bessere Variante mit Akkus, als die anderen mit USB-Ladung. Im Notfall oder bei den langen Reisen es gibt nicht immer eine Möglichkeit zum Laden. Kaufte, weil ich Tschernobyl-Kind bin, hab Angst vor solchen Unfälle für Rest des Lebens.

Was mir konkret auffiel, ist der sehr eingeschränkte Mess-/Anzeigebereich: "Skalenbereich von 0,05 bis 9,99 µSv / h (Mikrosiebenvert pro Stunde)" Es gibt etliche radioaktive Mineralien, die mehr als 9,99 µSv/h auf die Beine bringen. "Schlimm" wird es dann, wenn man auf Hotspots (z.B. Prypyat) stößt, die ein Vielfaches davon emittieren.

Sehr genaues Gerät, funktioniert zuverlässig. Konnte in befreundetem Betrieb für Materialprüfung Vergleichsmessung durchführen. Gleiche Werte wie professionales Referenzgerät.Habe das Gerät besorgt um Wildpilze auf Radioaktivität zu prüfen.Bin aber noch nicht dazu gekommen.

Tut, was es soll.

Es handelt sich hierbei um das Gerät RD1503+.Nachdem ich heute einen Test durchgeführt habe, welcher schon mit unterschiedlichen Strahlenmessgeräten durchgeführt wurde, kann ich nur eine Abweichung von maximal ca. 10% zu den professionellen Geräten feststellen. Für diesen Preis völlig i.O.. P.S. die Bedienungsanleitung ist nur auf Englisch, kann aber in Netz auch auf Deutsch heruntergeladen werden.

Immediately after opening the package and during putting in the batteries I saw the problems with the 'outdoor' part of this product. The battery compartment is not sealed, at all, no gasket, no o-ring and you can see the PCB from the battery compartment. The battery-cover is a very basic push-in type that doesnt hinge or properly clip into place let alone is a secure screw-down type. Could easily drop or even lose the battery compartment cover if changing batteries outside.The batteries themselves also want to jump out of the connectors which might be a good anti-vibration feature except for the loose battery cover. The frist time I turned over the product to turn it on a battery had jumped out of the connector and pushed the battery cover out a ways.There is a gap in the top of the device for some component and being poorly aligned there is a 2mm gap into the case - again I can see bare PCB and into the void of the case from the hole, zero protection from water in any way whatsoever.There is no strain-relief for the LCD screen, gently pressing on the case near the screen, i.e. a firm grip, led to 'white-out' of corners of the LCD, it would not take much to damage the screen. I also see no gasket or seal for the screen, somewhere where water could pool and ingress.If you are going to use this outside, put it inside a ziplock bag - the bag shouldn't interfere with readings much as there is no alpha-detection. Didn't seem to affect the background-level when i did it.However, the device seems to work as intented, the background level was nominal and placing next to an old smoke-detector showed a small increase in levels.The software is okay. The menus are usable and readable. The alarm-level is adjustable. The backlight is useful and the amount of time it stays on is adjustable. Its easy to use and works automatically after turning on. Only downside is that the smoothed and filtered values take some time to become accurate (which is understandable in background-level areas as there are few 'hits' to calculate a rate from). It does however show you the warm-up progress to display when you have an accurate reading which is nice.Being able to alter the smoothing in software might also be useful ( trade noise for faster results / faster scanning ).Overall the device is okay although it feels 'cheap' as it seems to work as intended. I've only spent a short time with it so long-term reliability is unknown.But, if you are expecting a weather-proof 'outdoor' device, it certainly isnt it that.3 stars becasue it works and is easy to use - but a misleading name and images: Don't get this thing wet at all, or keep it in the damp, or drop it, or hold it too tight, or lose the battery cover becasue a battery jumped out and pushed the easily removed battery-cover off.
