1、Alarm Function: Enter the alarm setting option and set the current dose alarm value and cumulative dose alarm value. The radiation monitor will automatically alarm when the detected radiation exceeds the alarm threshold regardless of whether the detector screen is in sleep or working state. 2、Geiger Counter: Counter for detecting radiation of β rays, γ rays and X rays. When the voltage is applied to the probe, the current gets to a certain range. Whenever a ray ionizes inside a tube to produce a pair of ions, it can be amplified to produce an electrical pulse of the same size. 3、Wide Application: Widely suitable for environments with ionizing radiation. Such as household radiation, survey, iron ore, power plant, industry, radiology department, radiation laboratory, etc. 4、Reliable Working: The product is a small and highly sensitive radiation exposure alarm, which is mainly used to monitor ray, y ray and hard β radiation. This instrument uses an energy compensated counter tube as the detector, which has the characteristics of high sensitivity, strong anti interference ability, and accurate measurement. 5、Premium Design: A powerful microprocessor and a TFT display screen are equipped, making operation easier. The product has three alarm modes of sound alarm, flash alarm, and vibration alarm, and the alarm threshold can be set freely. When the alarm threshold is reached, an alarm is issued to remind the staff to pay attention to safety in a timely manner.
