Key Features
⚛️ Detects Beta, Gamma & X‑Rays
Equipped with an energy‑compensated GM tube (Geiger‑Müller counter) – captures β, γ, and X‑rays. Ideal for environment monitoring, industrial safety, and personal protection.
🎛️ 5 Switchable Dose Units
Read your data in µSv/h, µGy/h, mR/h, CPS or CPM. No need to convert manually – great for professionals who work with different standards.
🔊 Triple Alarm Modes (Light / Vibration / Sound)
Choose audible, visual or silent vibrating alerts. Perfect for noisy workplaces or quiet environments where you don’t want to disturb others.
📊 Real‑Time & Cumulative Dose Alarms
Preset both dose rate and total accumulated dose thresholds. Get alerted the moment levels exceed your safety limits – gives you peace of mind.
🌡️ Environmental Temperature & Humidity Display
Monitor ambient conditions alongside radiation levels – a helpful reference for field surveys or lab work.
💾 Data Retention After Shutdown
Settings and cumulative dose records are saved even when the device is turned off. No need to reconfigure every time you power on.

Why Choose this Nuclear Radiation Detector?
✅ Solves the “Unknown Risk” Problem
Without a detector, you have no idea if you’re exposed to harmful radiation. The 886A provides continuous real‑time readings and programmable alarms, so you always know when levels rise above your preset threshold.
✅ Professional Sensitivity Without the High Cost
With an energy‑compensated GM tube and sensitivity of 80 CPM/µSv (Co‑60), it matches the performance of much more expensive units. You get lab‑grade reliability for field use.
✅ Built for Real‑World Situations
For radiation safety officers – Quickly switch between units (µSv/h, mR/h, CPS) to comply with local reporting standards.
For emergency responders – Vibration mode alerts you silently when searching in hazardous or noise‑sensitive areas.
For industrial workers – Monitor gamma and X‑ray leakage around sealed sources or inspection equipment.
For hobbyists & rockhounds – Test mineral specimens or check old ceramic / fiestaware for beta/gamma emissions.
✅ No More Guesswork with Dose Accumulation
Set a cumulative dose alarm (e.g., 1 mSv per month) – the detector tracks total exposure over time. Reset it after each task or keep it running for long‑term monitoring.
✅ Intuitive One‑Hand Operation
Four buttons: power/OK, up/down, left/back, right/set. Long‑press the right key to enter settings, adjust alarm thresholds, change clock, or pick your preferred alarm mode. The backlit LCD shows status at a glance.
✅ Practical Data You Can Trust
The real‑time display shows not only dose rate but also average / maximum values, cumulative time, and ambient temperature & humidity – all on one screen.
Note: This instrument is designed for detection and relative comparison. For legal or medical certification, always follow your local regulations and calibrated laboratory equipment.
