Portable Nuclear Radiation Detector with Data Storage — Geiger Counter, USB Type-C Powered, 3 AAA or CR1220 Backup

This portable Geiger meter includes built-in, non-volatile memory so key readings are retained after power loss — accumulated dose value, dose rate alarm threshold, and dose alarm threshold. Power can be supplied in multiple ways: install 3 AAA batteries, connect via USB Type-C, or use the included CR1220 button battery as backup. The unit also provides dual alarm functions to notify you when preset dose or dose-rate limits are exceeded.
