At the heart of the HT81 is a professional Geiger-Müller tube, ensuring sensitive and reliable detection of ionizing radiation particles and rays. This provides accurate readings you can trust for your safety assessments.

The clear digital screen shows real-time data intuitively, presenting radiation levels in multiple units: µSv/h (Microsievert per hour) and CPM (Counts Per Minute). This allows both professionals and enthusiasts to interpret the data easily.

Stay safe with instant notifications. The device emits a distinct clicking sound (traditional Geiger counter sound) for each radiation event detected. You can also set a customizable threshold alarm; when radiation exceeds your set value, the alarm intensifies, and the backlight flashes to provide a urgent warning.

The HT81 automatically stores maximum recorded values, allowing you to review peak radiation levels after your survey. This is crucial for identifying hotspots and for post-inspection analysis.

Built for fieldwork, the meter features a durable casing and a comfortable grip. The integrated kickstand allows for hands-free operation and continuous monitoring of an area. A protective cover shields the sensitive GM tube window when not in use.

Powered by standard alkaline or rechargeable batteries, the HT81 offers extended operation time, making it ideal for prolonged surveys and emergency preparedness kits.
