Eberline RM units

 

So anybody seen these or know about them?? ?I got two of the sample units but no controller.?

Its an Eberline radon working level meter. Basically a CAM. The detector faces the filter and counts alphas. Do you have a picture of the face of the instrumented. Does it look like this

No, all I got was the two sensor heads.? They were on a pallet of gear I bought at auction from NMSU.? Mostly Ludlum stuff but these were there and I thought they might be useful so i kept them...

No on the unit but I have that sensor in mt solid-state sensor collection. I see the PCB has a discriminator setting, but maybe the best approach to these surplus heads is to keep the sensor and charge coupled preamp, and substitute the electronics with a modular shaper block, then send that to a stand alone MCA.

For example the AMPTEK 8000D. It's set up for only external preamp/shaper heads already.

Later I'll show some of the CC preamp/shaper modules etc.

Also in my collection are flexible .s.s vacuum pipe for the small 25mm couplers, a manifold and electric-over-air relays.

And anything Dr. Prutchi used in his article is mine.

WLM = Working Level Meter (or Monitor). It outputs a number which is called the Working Level. A common term used in radon monitoring,

We can most likely get a manual if we don't have it already.

I'll have to check out Prutchi.? Has anyone bought his book?

I saw the value in these in the sensor more than anything else, which is why I kept them versus tossing on ebay for a C note or something.? Based on what I know now, I'd be kicking myself if I had!

Same here nick. Probably have a dozen solid state sensors or so that way. 3 I are still? in working Pylon WLx radon meters. Saved for a rainy day. Others came from units I scrapped ou already? but saved the pumps, valves, fittings, filter holders? and piping stuff\.

"I'll have to check out Prutchi.? Has anyone bought his book?:? I should have a signed copy in the library, and will find it when the stacks come upstairs to be sold on eBay. Not all but most.
