Bench tested to assure working condition.
The beautiful thing about these devices is that they are easy to fix. You might have a problem finding Eberline parts, but the circuit components are easily replaced and wiring diagrams are available. This is an old instrument but still a workhorse for some in the nuclear industry (if it works…. why replace?).
This is a fantastic meter to add a Counts.Pro to and bring it up to speed as a digital ratemeter/scaler where you can record every count measured. See eBay Item 401468071255.
