HH614 Geiger Müller Tube


I have been trying to find info on this tube since I got my HFS-P3 Chinesium pen counter, with little to no avail. By chance, a new user to radmon.org (gissio - welcome!) has already found the info and manufacturers website so I have compiled an English version datasheet for this tube (below). Many thanks to gissio for the info! ( https://github.com/Gissio/fs2011pro/tree/main/docs/tubes )

The HH614 is a new tube to the market, released in June 2022. It's quite compact but the size does limit it's sensitivity somewhat. It's gamma sensitivity is 10 CPS/mR/hr compared to the SBM20 at 22 CPS/mR/hr (Co60). Nonetheless, it is a quaint little tube that suits it's place in cheap Chinese counters nicely.
