Measures Gamma, Beta, and X-rays radiation. Detection range: 0.00~999μSv/h
Real-time, Average, and Cumulative dose display; Alarm threshold display
Alerts users via audio and visual alarms when the preset dose rate limit is exceeded. Alarm response time: 1 sec.
Powered by two disposable/rechargeable AA batteries, or use the USB cable that came with the unit to power the device.
Widely applied in environment evaluation, scientific testing on samples like: building material, hospital radiation therapy monitoring for cancer, food, water, indoor/outdoor-ray, and more
