- And that leads to a few questions:
-
- Some say they are “Geiger counters” while some say they are only “survey meters”. What is the difference between a Geiger counter proper and a survey meter?
- The probes: most of the counters/meters don’t come with probes. Some of the probes sold say that they are 600v, others say 900v. How can one tell which probe any given meter needs?
- Also I have seen that some probes say they are fitted with BNC connectors, what type of connector does the detector/meter usually have for the probe?
- Different units are in different states of function–some say tested, some say nonfunctional, others say untested. Is there any reason that they wouldn’t work after being stored for 40+ years? Are the parts that fail, commonly available?
