EdgeTech 0560 6450 professional meter/logger, and it seems to be analogous to the Testo 645 (same body, button configuration, ports, etc.). From the stockroom of a closing pharmaceutical lab. Tested March 2023 and working properly. Note that a normal 9V battery is a little loose in the chamber and will likely need something like a piece of cardboard to push it against the contacts. Battery and probes not included.
