Review: Must have in your proper’s kit - Face item appears to be well-made and accurate, it is within 00.01 to 00.02 of my secondary reader, and less a good time on a charge. Small enough to be discreetly placed in their home, measuring background radiation, ideal if you live near a nuclear plant or an industry that uses nuclear products in manufacture. To give you that extra little time right up in saving yours and your family’s lives. Easy to use, easy to set up, would recommend this product in your prep kit or for just piece of mind or curiosity of background radiation where you live. Review: Cool item - Good starter for adult only picks up beta and gamma radiation not alpha ## Features - Point matrix LCD display - The real-time graphics mode offers visualized changes in radiation in real time, so that the data changes are much easier to watch - USB data connection for connecting / charging with computer / PC / laptop GQ Soft Geiger Counter software - The big font - and text mode provides easy reading and maximum data information. e.g. CPM, date, time, elapsed time, UPS / H, MR / H, etc ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00IN8TJYY | | Batteries | 1 Lithium Ion batteries required.

Or are rechargeables ones provided.** A: The rechargeable battery is installed in the device. You do not need to buy other battery, you only need to connect it to USB port to charge it. **Q: can the beeper be turned off?** A: Both the clicker for incoming detections and the beeper for threshold/safety exceeded can be turned off. If you do that though, best watch the display closely, as the 3.5 mm socket on the side of it is an analogue data port, not a headphone socket. **Q: How is the time and date set? The 4 front buttons don't appear to access that function??** A: You can set the date and time from Main menu->Init setup->Date Time menu. **Q: How often it has to be calibrated (by third party specialist) to maintain accuracy?** A: Digital meters usually do not require further calibration once they leave the factory. The accuracy remains the same unless you physically change something in the settings. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Must have in your proper’s kit *by T***Y on 25 January 2026* Face item appears to be well-made and accurate, it is within 00.01 to 00.02 of my secondary reader, and less a good time on a charge.
