【Nuclear Radiation Detector】Y-M06 is a small and highly sensitive radiation dose alarm device, mainly used to monitor X-rays, γ-rays and β-rays. Measuring range 0.08uSv/h~9999uSv/h

[Multifunctional Geiger instrument] The instrument uses an energy-compensated 48mm GM Geiger counter tube as a detector, which has the characteristics of high sensitivity, strong anti-interference ability, and accurate measurement; it uses a powerful microprocessor and is equipped with TFT Display screen makes operation easier

[Intelligent alarm] The product itself has three alarm modes: sound, flash, and vibration, and the alarm threshold can be set arbitrarily. When the alarm threshold is reached, an alarm will be issued to remind the staff to pay attention to safety. The main technical indicators of the instrument meet international standards

✅【Nuclear Radiation Detector】Geiger counter nuclear radiation detector with built-in GM sensor, fast response time and high accuracy, able to detect Gamma, Beta and X-rays. Cumulative dose equivalent: 0.00uSv-500.0mSv. Energy range: 48KeV-1.5MeV ≤ ± 30%（for 137Csγ)

✅【Smart Alarm】Enter the alarm setting option to set the current dose alarm value and the accumulated dose alarm value. Whether the detector screen is in sleep state or in operation,the radiation dose detected exceeds the alarm threshold,the radiation monitor will automatically alarm. Light/Vibration/Sound 3 combined alarm modes to choose.

✅【Multifunctional Geiger Counter】Our the geiger counter has other various setting, such as alarm setting, system clock setting and unit setting & language change,you can operate in English (default) or Chinese. Easy one-handed operation.

NUCLEAR RADIATION DETECTOR --Radiation detector meter uses a professional Geiger counter and an energy-compensated GM counter tube as the core sensor for accurate detection of beta, gamma and x-rays. Fast detection speed, strong anti-interference capability, high sensitivity, wide measuring range and long service life. Detection range: 0.08uSv/h~9999uSv/h. Radiation dose data is updated in real-time per second.

SMART ALARM--Radiation detector can be set to any cumulative alarm value and dose rate alarm value. When the radiation value exceeds the set value, the radiation dosimeter will automatically emit a loud sound and a flashing screen for alarm, avoiding the risk of radiation in daily life.
