Is there any data on the longevity of the tube when ran continuously? I have a mightyohm kit, but I decided against building a monitor device around it because I've heard rumors that the tube quickly degrades if ran 24/7. I don't think I ever saw any kind of measurements that would confirm that rumor though.

Nice! (Through the timestamps of the detector's reactions.)

Aliexpress seems to have sensors at ~30 GBP, but still a little high for something not super useful
