Here is a hand probe I whomped up today. The element is one of the LND 7311's 2 inch 900V pancakes that are also used for the LENi Short Stack. This one is...
After bending the Beta shield, it seemed obvious to make one with a hole in it, to add paper or other absorbers ( Alpha shield). The Beta shield is shown in...
Is a scint + PMT *always* better than a GM tube? Not just on the basis of being able to discriminate energy levels, but on the basis say of volumetric or...
... Hi all, GM are normally more versatile than a scint. A scint that is good for high energy gamma may be very poor for beta and vice versa. I have an ex...
Well, this monday, as I mentioned, I went to the Florida BRC. Asked, and got, a C/M only CD V-700M meter face. I was a dummy, and almost left without having...
Another method to try, is soaking the old (paper) stickers with WD-40. It seems to do a good job of loosening the residue and making the paper come apart. If...

I never encountered that problem with my ENi's plastic face befor eI got it replaced with a sealed one. I'm using a sealed face on my CD V-700M. Thanks for the...
... For anyone not already aware, this need not be a huge problem - the v715, v720, v717, etc all use the same 50uA meter movement, they can be purchased for...
A much simpler and better option would be to get a sealed face from Surplus Stuff at http://www.surplustuff.com/radiolog.html . These are the sealed,...
... It doesn't seem obvious to me that there is much (if any) advantage to the metal-cased meters over the plastic in terms of ruggedness. When not installed...
VERY GOOD POINT Justin on the CDV 715 meter, will look into that pronto! We found another good use for a CDV 715 besides door stop. ! HAD NOT OCCURRED TO ME....
The electrical junk inside is what is ruggedized. It's designed to take shock, hence the "ruggedized title." The magnet, etc. are designed to take much more...
Of about 20 or so CDV 715's down on the shelf, only 3 had the metal meters. The others have sealed plastic meters. I took one of the metal ones apart...it...
Mr. Dowell, if you want more of these things, ask your state RIM&C. They may wish to part with one or two. Considering today's precarious situation, I'd keep...
I agree with Robert 100%. If I had to have only 1 probe, it would be a pancake GM. Alpha Beta and Gamma versatility along with excellent sensitivity. Scints...
... THAT, ... Ah. Are you concluding this from the fact that one has "Do not open - ruggedized" written on it, and the other doesn't, or have you seen some...
Nope, besides the fact the meter itself says its ruggedized, Kubric says the metal faces are more rugged than the plastic, and my state RIM&C actually removes...
... GeigerCounterEnthusiasts@yahoogroups.com, "civildefenseinfo2002" ... Ah, cool. I wasn't sure if you had other reasons. Soooo, what are they doing with all...
Yes the meters are all good with the exception of the ones with ceramic magnets. You can tell these because they look different. The magnet is a little...
As far as I know, all of the plastic faces are thrown out. I'm not sure, but I believe beforehand they are pried open, and the original dial face saved. I'm...
