Overview
The GQ GMC-800 Nuclear Radiation Detector is a portable and professional-grade Geiger counter designed for accurate and rapid detection of Beta, Gamma, and X-ray radiation. Developed in the USA to meet NIST and NRC standards, it provides precise, reliable, and fast readings suitable for personal, group, and professional use.
This radiation detector features a large color TFT LCD display capable of showing multiple dosimeter readings at once, including real-time dose rate, cumulative dose, and exposure data. Users can switch between four function screens instantly using a single key, allowing immediate assessment of radiation levels both indoors and outdoors.
The GMC-800 incorporates five types of alarms: visual LED, audio click, vibration, voice, and screen color bar, ensuring that everyone, including vision- or hearing-impaired users, is notified when radiation exceeds a set threshold. Alarm levels are fully customizable for personal safety and professional monitoring.
Equipped with a rechargeable Lithium Ion battery and Type-C charging/data cable, this radiation detector supports long-term data logging, history preview, and global data sharing. Advanced menu features and intuitive user interface allow customization of light/dark mode, color schemes, and graphic display preferences for enhanced readability and comfort.
