Re: Mirion PDS 100G, Spectrometric Personal Radiation Detector

Svilen - Good to know, as I thought perhaps there was some internal problem with the bluetooth adapter on the PDS itself that was not reporting an error on startup of the PDS (which it checks). I was worried that I would have to send it back to the UK for a replacement. Hopefully our experience will...

Re: Mirion PDS 100G, Spectrometric Personal Radiation Detector

Ran some spectrums this morning...

Fairly happy so far with the results, and a very nice litt...

Re: Mirion PDS 100G, Spectrometric Personal Radiation Detector

I removed the device from Bluetooth and re-paired it with my laptop PC several times and nothing happened. Uninstalled and reinstalled Bluetooth drivers in the OS device manager and nothing happened. Uninstalled and reinstalled the PdsMass application and all is working now. Uninstalling and reinsta...

Re: Mirion PDS 100G, Spectrometric Personal Radiation Detector

Stefan - The first picture I posted showed that Bluetooth was on and discoverable. Additionally the picture shows (highlighted in yellow) that the device "PDS A11595" (which is the PDS-100G) is "Paired". So I'm still at a loss as to why the PdsMass will not communicate, when it appears that WinOS se...

Re: Mirion PDS 100G, Spectrometric Personal Radiation Detector

Thanks, that is what I initially thought and had already checked. Windows has assigned port 3 and 4 to bluetooth. When I use port 3 in the com configuration I get the message at the lower left of the PdsMass screen that says "Communication is initialized". I also get a "green B" in the bluetooth sym...

Re: Mirion PDS 100G, Spectrometric Personal Radiation Detector

I'm having some issues with the software communicating with the PDS-100G (please see attached pictures). Bluetooth is setup on my Win10 Laptop and the PDS-100G is paired. Bluetooth paired.jpg The PdsMass software seems to communicate with the Bluetooth driver and com port. configuration.jpg initiali...

I’m now another happy owner of the PDS-100G. Mine just arrived in very nice condition, like others mentioned. (edited...) Cheers, Tom

Re: Geiger Müller tubes on flights

I have never seen anything on the LND web site or in their specifications or literature describing an altitude or atmospheric pressure limit for the 7311 pancake detector or any other they manufacture. However, in 1987, Ludlum (maker of popular pancake detectors based on the LND 7311 detector) issue...

Re: Harshaw 16X16MKS12/3.5 B-X scintillation probe

Hi Kyle - Could be a number of issues with either the crystal or PMT (or the VD value is too low for the meter to drive efficiently). Most detectors that size I have seen are easily disassembled, however it would be nice to see some pictures and more descriptions of your testing to offer better opin...

Re: Greeting from Canada... HELP!

Raphael I believe that seller does not rework the voltage divider values for that listing. It is a lot of work to rework it, and the listing would probably clearly indicate that if it were the case (as I clearly do in my listings for this detector). Just simply changing out the wires and coupling th...
